SYSGO optimizes multicore support and energy efficiency in PikeOS 4.2

By Nick Flaherty

SYSGO has optimized its PikeOS hard real time operating system for multicore designs with a hypervisor and separation microkernel.

Release 4.2 has been designed specifically for systems and applications that need certification according to safety or security standards such as DO-178B/C, EN 50128, ISO 26262, as well as Airbus SAR and Common Criteria requirements.

A fine granular kernel locking that enables all cores to continue their processes even while one of them executes a system call, greatly reducing unproductive processor cycles. Other cores may only be blocked, if they attempt to access the exact same resource in order to control interference. This is necessary for the latest ARINC-653 multicore standard.

PikeOS 4.2 also improves the energy efficiency of embedded systems as it allows the developer to manage multiple hardware clock devices and frequencies on the same board - including System on Chip (SoC) internal and external clocks. This way, applications as well as IPs on the SoC can easily be stopped and restarted as needed, reducing both resource and energy consumption.

PikeOS 4.2 provides a modern compact and certifiable Hypervisor technology with separation microkernel, implementing robust time and resource partitioning, which allows interference channels to be managed within your certifiable project. In addition, PikeOS 4.2 provides time schedules for individual resource partitions by core, where direct CPU affinity may be used to implement core separation for ultra critical partitions to be managed with PikeOS.
"Being the leading European operating system manufacturer, we have a long track record in supporting our customers in the entire certification process", said SYSGO's VP of Marketing & Product Strategy, Franz Walkembach. "With PikeOS 4.2, these customers have now access to a software platform that has been strictly designed with certification in mind. What is more – they will also benefit from an entire ecosystem around this platform which brings together the expertise of SYSGO, our partners and the scientific community."

PikeOS 4.2 will be available this month for multicore CPUs, including ARM v7 and v8, 32 and 64 bit PowerPC and 32 and 64 bit x86. Board Support Packages (BSPs) are available for a wide selection of silicon vendors like NXP/Freescale, Renesas, Intel, Xilinx and Altera.

The first product based on PikeOS 4.2 will be SYSGO’s own safety and security certification kit that will enable customers an efficient safety or security certification kick-off element. Therefore helping to reduce time spent during long certification programmes.
