Lattice FPGAs to link to Octeon II multicore processors
FPGA maker Lattice Semiconductor has announced plans to interoperate between Cavium Networks’ OCTEON II CN63XX multicore network processors and its LatticeECP3 family via a Serial Rapid IO (SRIO) Specification 2.1 link. SRIO is commonly used in 3G/4G wireless base stations and wireline switches and routers where low latency is critical. Cavium’s OCTEON II processor incorporates two to six cnMIPS64 cores and SERDES-based I/Os, including SRIO. Lattice’s ECP3 device has the lowest power in a mid-range FPGA family, rich memory density, DSP blocks and SERDES I/Os capable of supporting SRIO.
Cavium and Lattice have already begun executing their plan to demonstrate SRIO interoperability, and both companies will announce updates as they become available. “The addition of the SRIO interface in the OCTEON II processors, along with the wide variety of other standards-based interfaces, provides a new low-latency connectivity option,” said Tasha Castañeda, Senior Strategic Alliance Manager at Cavium Networks. “We are pleased to add Lattice to Cavium’s PACE (Partnership to Accelerate Customer End-solutions) ecosystem in order to offer our customers a strong FPGA design solution.”
“This SRIO interoperability testing will strengthen our rich portfolio of wireless IP," aid said Ted Marena, Director of Business Development for Lattice. "We are working to introduce future bridging applications for the OCTEON II and our ECP3 family, including SRIO to CPRI, SRIO to PCIe and SRIO to SGMII.”
