Farewell to the Internet Streaming Media Alliance

Merges with MPEG Industry Forum

The Board of Directors of the MPEG Industry Forum (MPEGIF) and Internet Streaming Media Alliance (ISMA) have agreed to merge the two organizations in a move that marks the end of the ISMA. In a slightly strange move, MPEGIF members will become ISMA members but the organisation will go forward as MPEGIF within the existing ISMA Californian non-profit corporation. As a result, MPEGIF’s current structure as a Swiss association will be dissolved, but ISMA willbe no more.

“ISMA delivered massively important technology contributions resulting in great value and lasting benefit to our industry over the years,” said Sebastian Moeritz, President of MPEGIF and CEO at dicas.

"MPEGIF is pleased to take this opportunity to increase its strength and to gain the operational efficiencies we will be able to bring to our members", said David Price, Vice President of MPEGIF and Vice President at Harmonic. "The industry is facing huge changes in the way video is enjoyed and the advocacy of MPEGIF for solution wide standards is more vital than ever."

“ISMA’s highly successful standards will gain additional visibility through the merger, and will continue to be widely available to the broader industry through the success and influence of MPEGIF,” said Yuval Fisher, Chair of ISMA and CTO of RGB Networks.

Founded in 2000, ISMA was an alliance for the adoption and deployment of open standards for streaming rich media such as video, audio, and associated data over Internet protocols.

An Altera Arria II GX FPGA combined with TI DSP signal processing provide exceptional compute power in a video XMC platform.
Two TI TMS320DM6467 DSPs provide processing capability to achieve two streams of up to 1080p H.264 (or JPEG 2000) encoding. Up to four streams of SD input data can be compressed in parallel. The encoded bitstream can be accessed via PCI Express, or output directly as Gigabit Ethernet RTP/UDP packets.
High-speed A/D devices - supporting resolutions up to 1,600 x 1,200 for graphics type inputs and 1,920 x 1,080 for HD video inputs - provide input digitization of the various supported analog video formats. The FPGA controls data capture and routing and can be used in a variety of ways, while the TI DSP co-processors provide efficient and streamlined video data processing. If required, the system can be loaded with custom FPGA and DSP code to perform a broad range of video processing functions on the video input streams.
Data input and output is available using a carrier card, PCI Express connectivity, or via rear I/O. Analog or digital input data can be supported through the rear I/O connectors. Up to 768 MB of DDR2 SDRAM is supplied on-board. The FPGA has 256 MB and each DSP device has 256 MB.

Xilinx puts multicore on FPGA

Two ARM Cortex-A9 cores on 28nm FPGA

Xilinx is putting a multicore processor architecture onto its next generation of FPGA. The Extensible Processing Platform is a single chip that combines two 800MHz ARM Cortex-A9 MPCore processor-based subsystems with 28nm FPGA fabric to add extra functions for system and ASIC protoyping.
This is a significant change, as it provides embedded systems designers with a processor-centric design and development approach rather than an RTL hardware approach. Xilinx sees this has a way of achieving the compute and processing horsepower required to drive tasks involving high-speed access to real-time inputs, high-performance processing and complex digital signal processing — or any combination thereof — needed to meet their application-specific requirements, including lower cost and power. 
This isn't that new, as Xilinx has integrated PowerPC cores into the fabric of its FPGAs before for telecoms applicaitons, but this is a return in force to the software approach with a more popular embedded core.
“Today’s embedded software developer is being tasked to build complex applications that require tremendous levels of system performance, and they need to deliver that performance within tightly managed cost, schedule and power budgets,” said Vin Ratford, Xilinx Senior Vice President for Worldwide Marketing and Business Development. “By creating an architecture within a familiar ARM processor-based development framework, this new Extensible Processing Platform can be the engine of innovation for many design teams held back today by performance bottlenecks.”
A software-centric development flow is enabled by a processor-centric approach which presents a full processor system – including caches, memory controllers and commonly used connectivity and I/O peripherals – that boots and can run a variety of operating systems (OS) at power-up, such as Linux, Wind River’s VxWorks and Micrium’s uC-OSII. 
The programmable logic is tightly coupled with the processor system through the high-bandwidth AMBA-AXI interconnects to accelerate key system functions by up to 100x, using off-the-shelf and/or custom IP. This architectural approach addresses common performance bottlenecks between these parallel and serial computing environments, memory and I/O. It also gives the processor system configuration control of the programmable logic, including dynamic reconfiguration.
 “Taking advantage of the parallelism of programmable logic is an excellent method for overcoming cost and power challenges in systems that require significant levels of high performance,” said Simon Segars, President of ARM in the US. “Xilinx’s new architecture abstracts much of the hardware burden away from the embedded software developers’ point of view, giving them an unprecedented level of control in the development process.”
Software developers can leverage their existing system code based on ARM technology and use off-the-shelf open-source and commercially available software component libraries. Because the system boots an OS at reset, software development can get under way quickly within familiar development and debug environments using tools such as ARM’s RealView development suite and related third-party tools, Eclipse-based IDEs, GNU, the Xilinx Software Development Kit and others.
Unrivaled Performance to Enable New Applications
Demand for higher levels of embedded system performance is being driven by end market applications that require multifunctionality and real-time responsiveness, such as automotive driver assistance, intelligent video surveillance, industrial automation, aerospace and defense, and next-generation wireless. In the automotive sector alone, with greater than 50 million cars produced each year, and an estimated 600 million motor vehicles on the road, today’s $1.3-billion-dollar driver assistance market is expected to grow to $5.8 billion by in 2017 as manufacturers deploy more embedded systems in their vehicles to make them safer.
With statistics showing that 60 percent of front-end collisions could have been avoided with an extra .5-second response time, or that driver fatigue accounts for an estimated 30 percent of all driver fatalities, the motivation to leverage technology to save lives is clear. As developers of driver assistance systems pack more compute power into their applications, radar and infrared sensors, cameras and other system components must be installed into confined spaces within the automobile. The new Xilinx Extensible Processing Platform offers a single-chip solution for optimizing application-specific hardware/software partitioning and accelerating functions in hardware to drive complex algorithms. This enables customers to further differentiate their embedded systems to gain a competitive advantage in their markets.
In a market expected to reach $46 billion by 2013, developers of new intelligent video technologies need processing platforms for building applications that can automatically monitor video patterns and body language, combined with audio, to make intelligent decisions and send alerts, thus reducing the chance for errors. The technology is already moving to full high-definition video and frame rates up to 60 frames per second, but current solutions do not offer sufficient compute power for image processing and advanced analytic functions. The dual Cortex-A9MPCore-based processor system, coupled with the massive parallel-processing capabilities of the programmable logic, enables this capability. Developers also gain an opportunity for innovative algorithm design, scalability and field upgradability within a familiar ARM-based design environment.   
Wireless telecommunication is being driven by the need for lower power, smaller physical form factors and reduced development costs, to support an ever-increasing number of users and data-hungry applications. New technologies such as 4G LTE (Long-Term Evolution) can address bandwidth requirements, but smaller, more efficient base stations are essential to meeting overall market requirements. The Xilinx Extensible Processing Platform will help developers of next-generation wireless base stations to meet these needs by providing high-bandwidth parallel processing of 4G signals in combination with multiuser data management on Cortex A9 processors – all in a small, power-efficient, cost-effective integrated solution. Because the platform is extensible, developers have the flexibility to implement future equipment updates and performance upgrades of both hardware and software.
The new Extensible Processing Platform is part of Xilinx’s Targeted Design Platform strategy, which provides customers with market- and application-specific environments that are easy to use, enabling them to evaluate and understand technology, and finally provide application platforms that can be modified and extended to accelerate their development time and focus on differentiation.

IBM develops nanoscale MRI imaging - video

Taking images of a virus

Researchers from IBM's Almaden Research Centre and Stanford University have developed a new technique for seeing particles at the nanoscale using magnetic resonance imaging (MRI) techniques that are already widely used in hospitals.

They have combined ultrasensitive magnetic resonance force microscopy (MRFM) with 3D image reconstruction to achieve MRI with resolution under 10 nm. The image reconstruction converts measured magnetic force data into a 3D map of nuclear spin density, taking advantage of the unique characteristics of the “resonant slice” that is projected outward from a nanoscale magnetic tip. The basic principles are demonstrated by imaging the 1H spin density within individual tobacco mosaic virus particles sitting on a nanometer-thick layer of adsorbed hydrocarbons.
The result  represents a 100 million-fold improvement in volume resolution over conventional MRI and demonstrates the potential of MRFM as a tool for 3D imaging on the nanometer scale.

CriticalBlue and Freescale collaborate to streamline and simplify multicore software development

CriticalBlue’s Prism development environment now available for QorIQ multicore processors

CriticalBlue is working with Freescale Semiconductor to make its Prism development environment available to support Freescale’s QorIQ multicore processor families. Software developers will be able to migrate, optimise and verify their existing software applications on Freescale’s multicore platforms based on Power Architecture technology.
 As communication equipment vendors migrate from single-core to multicore designs, they face the complex and time consuming task of rewriting their code to work with multiple cores. The addition of Prism support to Freescale’s QorIQ multicore ecosystem will help customers preserve the value of their legacy code while designing with new multicore platforms. The Prism tool helps eliminate guesswork by profiling the code base and suggesting which routines are best to leave in serial sequence and which ones are candidates for parallel sequencing across multiple cores. With this capability, Freescale customers are able to optimise their software code to achieve maximum hardware performance.

Risks to radio systems from wind turbines

The wind turbine at Hartley in ShinfieldImage via Wikipedia
I'm a great supporter of renewable energy and green electricity, and the SmartGrid will have to combine energy production from a variety of approaches, but Analysys Mason are pointing out that wind turbines may well cause problems for radio systems, particularly RF embedded control.
Although wind turbine blades are largely made of non-conductive plastics and similar composite materials, they are large constructions and the latest designs contain metal reinforcements and conductors for lightning protection. A single turbine therefore presents a significant but very geometrically variable ‘radar cross section’ that has the potential to reflect or diffract radio propagation waves, and cause a delayed multipath component that may interfere with the original radio link signal, says the group. The more windmill stock a farm has, the more unpredictable the reflections and diffractions of radio waves become, with potentially a far greater impact than may otherwise be expected.
The potential for interference is of particular concern for the utilities industry, which makes quite extensive use of scanning telemetry systems and SCADA (System Control and Data Acquisition) systems to monitor and control its infrastructure. These systems are often ‘fail-safe’ so that operations are automatically suspended if, for example, the SCADA system fails. Thus interference from wind turbines could potentially result in the shut-down of power and water supplies if serious interference is detected.
A number of Analysys Mason consultants who are involved with the utilities industry are becomingly increasingly concerned about the vulnerability of one particular link type, mainly because of a lack of understanding and a lack of relevant research within the telecoms industry. The link type in question is that operating at around 460MHz, which is often used for telemetry or other SCADA applications. Within these applications the 460MHz band is often selected for particular links because the link path profile is non-line of sight, and this band permits the deployment of a diffracted path route between each link end as a design parameter. In these cases the link path loss is significantly greater than the nominal free-path loss that would otherwise exist for the line-of-sight case, and different interference design rules must be applied (as discussed below).
Across the UK, there are a number of radio links at 460MHz where the path profile relies on a terrain-diffracted path, rather than direct line of sight. From a system design perspective this is often why the comparatively low frequency of 460MHz has been selected, as it enables the use of a diffracted path, and
the impact of wind turbines and farms needs more field measurements and study to quantify the interference mechanisms, particularly in situations where the basic path is diffracted. 
There is a sell of course - at Analysys Mason they have been studying all the publicly available material on wind turbine interference to radio propagation and have developed user-friendly computer models to evaluate and predict appropriate clearance zones around single and multiple wind turbines.

GE Satellite provide Ku data uplinks to NASA unmanned science mission

Ex-military UAV flies across Pacific taking measurements

GE-Satellite, a leading provider of satellite services in the Pacific, was recently chosen by NASA to provide Ku-band satellite connectivity for its ground breaking science mission to study atmospheric and environmental conditions across in the Pacific via Unmanned Aerial Vehicle (UAV). 
The NASA Global Hawk Pacific (GloPac) campaign, the first Earth Science mission to use the UAV for atmospheric and environmental research, demonstrates GE-23's capability to support a broad range of mobile broadband applications in the Pacific.
The GE-23 satellite, ideally suited for the mission because of its dynamic coverage in the Pacific, enabled continuous communications throughout the Global Hawk's 14-hour maiden voyage. “The Global Hawk's ability to autonomously fly long distances and remain aloft for extended periods brings a new capability to the science community for measuring and observing large areas of the Earth,” said NASA.
The Global Hawk payload includes an antenna to allow it to continuously transmit data and images via the GE-23 satellite. As part of the environmental research mission, scientists measured atmospheric conditions including greenhouse gases, ozone-depleting substances, aerosols, and constituents of air quality in the upper troposphere and lower stratosphere.  Future missions include observations from the equator to the Arctic Circle, and west of Hawaii.
“We are thrilled to be a part of the NASA Global Hawk mission and this exciting new chapter of science history,” says Andrew Jordan, President and CEO of GE-Satellite.
NASA has three Global Hawks, all previously used by the US Air Force, now fitted with 11 scientific instruments to conduct atmospheric research. The Hawks carry over than 400Kg of scientific gadgets, can operate at altitudes up to 65,000 feet and stay aloft for 30 hours while flying a distance of more than 12,600 miles - making the long range continuous measurements possible for the first time.

Synapse and Silicon Labs Launch Wireless Module for Mesh Networks

Sub-GHz connectivity for smart meters, building automation and personal medical devices
Synapse Wireless and Silicon Laboratories have teamed up to develop a wireless mesh network solution that combines the SNAP network operating system with Silicon Labs' Si1000 wireless microcontroller (MCU). The combined software/hardware solution - the Synapse RF Engine module - makes it easy to deploy a scalable, ultra-low-power, small-footprint wireless mesh network for a wide range of applications including smart meters, wireless sensors, Zigbee networks, building automation, commercial lighting control, personal medical devices and RFID asset tracking systems.

The SNAP network operating system provides a high-performance wireless mesh network protocol that supports Internet-enabled, wireless machine-to-machine communications, and offers an embedded Python interpreter for easy application development. Providing the intelligence behind the Synapse RF Engine, SNAP runs on Silicon Labs' Si1000 wireless MCU, which combines an ultra-low-power processor core with a high-performance sub-GHz RF transceiver delivering high-bandwidth and extended-range wireless connectivity.

SNAP allows wireless applications to be developed quickly and easily using Python's English-like scripting language instead of complex embedded programming. The developer simply adds the application to SNAP, residing on the RF module, over-the-air. No embedded wireless programming experience is required to develop applications and deploy them to physical SNAP nodes. Instead of being burdened with the underlying complexities of a wireless mesh network, the developer can focus on getting the application to market quickly.

The intelligent SNAP network operating system enables nodes to join the mesh network instantly and the software's over-the-air programming and Python interpreter ensure easy, fast and flexible application development.

The Synapse RF Engine provides a turnkey hardware/software solution that developers can deploy immediately in their end products. It also offers an easy-to-use development platform for system engineers who want to migrate their wireless designs to high-volume applications using the Si1000 MCU running SNAP as embedded firmware.

"The collaboration between Silicon Labs and Synapse has resulted in a best-in-class, sub-GHz wireless networking solution that combines the industry's lowest power wireless MCU with the sophisticated networking and Internet connectivity capabilities of SNAP," said Wade Patterson, Synapse Founder, President and CEO. "The jointly developed wireless platform will streamline the development of cost-effective and energy-efficient mesh networks."

Developers using the Si1000-based Synapse RF Engine will have access to the full product and service offerings from Synapse. This includes custom design services for solving tough, engineering challenges in OEM product design; the Synapse Portal wireless application development environment for ease in network management and rapid application development; and SNAP Connect, for seamless integration to the Internet.

"The combination of the Si1000 wireless MCU and SNAP provides a comprehensive mesh networking solution for ISM band applications in the sub-GHz range," said Mark Thompson, vice president of embedded mixed-signal products at Silicon Labs. "Using this combined hardware/software solution, developers can get their wireless applications up and running quickly and easily while benefiting from the power-efficient, battery-saving capabilities of the Si1000 MCU and its exceptional wireless range and performance."

Synapse SNAP Network Operating System

Synapse's SNAP network operating system is an Internet-enabled, IEEE 802.15.4-based, instant-on, multi-hop, mesh network, software solution designed to cost-effectively run efficiently over a range of popular microprocessors and microcontrollers. SNAP has a very small memory footprint of only 45 kB, thereby leaving more space for user applications. SNAP can support up to 16 million nodes in a single network. Since these are peer-to-peer mesh networks, there is no single point of failure: any node can talk directly to any other node that is in range, and any node can talk indirectly to any other node via intermediate nodes - SNAP networks are self-healing. Users can interactively develop applications using a high-level English-like language called Python. No embedded programming experience is required. Synapse currently has more than 900 registered SNAP users.

Silicon Labs Si1000 Wireless MCU
The Si1000 wireless MCU, a member of the Si10xx family, combines a 25 MHz 8051 core, EZRadioPRO® sub-GHz RF transceiver, 64 kB of flash and a 10-bit ADC - all in a compact 5 mm x 7 mm package. As the industry's only sub-GHz 8-bit wireless MCUs, the Si10xx family offers market-leading RF performance with the highest output power and sensitivity and lowest power wake-up transition. The Si10xx family's integrated power and low-noise amplifiers enable an RF link budget of greater than 140 dB without active external elements, resulting in extended range, higher bandwidth and lower power consumption. The industry's most power-efficient wireless MCU solution, the Si10xx family provides the lowest current in common modes of operation. The wireless MCUs offer the lowest active-mode current consumption (160 microamps per MHz). In sleep mode, they consume only 315 nanoamps using the internal low frequency RTC. In deep-sleep mode, they can operate on as little as 25 nA with full RAM retention.

Pricing and Availability
The Si1000 MCU-based Synapse RF Engine module is available today from Synapse and MSRP priced at USD$29 for 1-unit quantities with volume discounts available. The Synapse SNAP evaluation download for the Si1000 MCU is also available from Synapse.

Texas Instruments embraces Linux for C64x DSP processors

Reflects embedded industry move to open source
TI has announced Linux kernel support for its TMS320C64x digital signal processors (DSPs) and multicore system-on-chips (SoCs) targeted for applications such as communications and mission critical infrastructure, medical diagnostics, and high-performance test and measurement. As customers move towards open source initiatives as a key element of their products, application developers can benefit from the availability of Linux on TI’s  DSPs by having less software to develop, and focusing more on differentiating features and software in their applications.

“TI’s C64x processors have an enviable footprint in signal processing oriented high-performance multicore applications,” said Olaf Soentgen of Nash Technologies. “The introduction of Linux support expands the utility of the C64x DSP processors into portions of these applications that traditionally have been reserved for RISC cores. We are taking advantage of Linux availability on TI’s SoC to lower the cost and simplify the development of femtocell base stations.”
TI’s C64x Linux effort is a community collaboration with considerable support already in place. As part of the effort to port the Linux kernel to the C64x ISA, Code Sourcery is developing a complete tool chain including support for the GNU Compiler Collection (GCC) and the GNU Project Debugger (GDB). The project’s goal is that both the C64x Linux kernel and the GCC / GDB tools will be accepted by and the Free Software Foundation, making both fully supported as open source community projects. In addition, TI will sponsor a Linux-C64x portal and a community-oriented distribution program to facilitate communication and development around this technology.  ENEA is making its open source, scalable multicore communications stack available to the C64x Linux community, as well as offering advanced multicore platform software and debugging tools.  Nash Technologies is implementing features ranging from advanced chip level functions, such as multicore interprocessor communications, to complete LTE protocols.  PolyCore Software, also an early community participant, is implementing the MCAPI multicore communications framework.
 “Our customers are rapidly moving towards open source as a critical element of their solutions,” said Brian Glinsman, general manager of TI’s communications infrastructure business. “Because of the C64x-basedDSP processors’ low power consumption and cost effectiveness, customers are interested in running traditional DSP MAC/PHY and codec algorithms as well as classic RISC control code and protocols on our DSPs. TI’s embracing of Linux and an open tool chain for the industry workhorse C64x DSP processor makes this kind of integration practical.”

Product support for the C64x Linux kernel will be available for TI’s TMS320C6472, TMS320C6474, TMS320C6455 and TMS320C6457 DSP processors in 3Q10.

Dust Networks launches ARM Cortex-M3 system chip for 802.15.4

World's lowest power RF so far

Dust Networks is an intersting company as a leading supplier of wireless sensor networks (WSN). It is using the low power ARM Cortex-M3 processor for a new family of system-on-chips (SoCs) that include an on-chip power amplifier (PA) that will be the basis for a variety of upcoming standards-based WSN products, including IEC 62591 (WirelessHART), 6LOWPAN (IP), and Zigbee PRO products. This is key for the development of the SmartGrid.
The SoCs will feature:
  • A 32-bit ARM Cortex-M3 processor and rich interfaces enable a powerful computing platform while conserving power.
  • The world's lowest power IEEE 802.15.4 radio: a new benchmark is set, with a mere 3 mA transmit at 0 dBm and 3 mA receive current, delivering 5-10 times the battery life of competing technologies, and further expanding the applicability of energy harvesting power sources.
  • Extended range capabilities, with up to 8 dBm output power on-chip PA and an optional external power amplifier.
  • The industry's first IEEE 802.15.4E-ready product, incorporating the emerging standard for time synchronization and channel hopping, while providing legacy support for 802.15.4-2006.

"Our new SoCs are geared to deliver the highest performance while running at a fraction of the power of competing silicon," said Dr. Kris Pister, Chief Technologist at Dust Networks. "In selecting the ARM Cortex-M3 processor for our SoC, we did not have to trade-off performance for power. Dust Networks new IEEE 802.15.4 SoCs will require less than one-tenth of the energy per operation of comparable SoCs."

The level of systems integration in the SoCs is very high, including on-chip power amplifier, DC-to-DC converter, 10 bit ADC and a built in temperature sensor. With configurations up to 512kB of flash and 72kB of RAM, these SoCs will have both the highest computational horsepower of any 802.15.4 chip on the market, and the lowest power consumption. In doze mode, with full processor state and RAM retention, current consumption is under 1uA.

"Low power radios such as IEEE 802.15.4 and wireless mesh networking, epitomized by Dust Networks' TSMP protocol and its "Smart Dust" roots, have transformed the industrial wireless sensor network landscape", said Mareca Hatler, ON World research director. "With the introduction of ultra low power versions of SmartMesh IP (6LoWPAN) systems and ZigBee products, Dust Networks will expand the growing number of 'Smart World' applications that span Smart Buildings, Cities, Government and Homes."
