Posedge selects EnSilica's eSi-3250 processor to perform wire-speed routing at multi-gigabit rates Posedge, a semiconductor intellectual property and solutions provider based in Sunnyvale (California, USA), has licensed EnSilica'sa high-performance eSi-3250 32-bit processor core for an innovative, new Residential and SMB Gateway solution that performs Wire-Speed Routing at multi-gigabit rates.

Posedge will initially use its next generation Residential and SMB Gateway processor in a 40 nm SoC project it is currently developing for a customer. Posedge is using both EnSilicas Windows and new Linux-based toolchain to underpin the development process.

Posedges new Residential and SMB Gateway processor is an innovative, 7-core design that utilises six eSi-3250 cores as identical datapath processors performing such functions as packet classification and packet editing, and another as a utility processor implementing high level functions, IPSec software and TCP offload. Posedge chose the eSi-3250, the top-end core in EnSilicas eSi-RISC family of processors, following an extensive evaluation of three different CPU cores, as it exhibited the best cost/performance metrics.

Of the three processors that we evaluated, the eSi-3250 was a clear winner, proving extremely conducive to the implementation of multicore SoCs, said Chakra Parvathaneni, Vice-President of Marketing for Posedge. EnSilica has provided us with an extremely flexible set of cores in the configurations required to deliver the functionality we need within a single SoC. The eSi-3250 is also backed by a toolchain capable of supporting multicore debug and validation. We are now actively looking to use the eSi-RISC family in other solutions we are developing, including a new 802.11 WLAN MAC/PHY solution.
