Posedge standardizes on EnSilica’s eSi-3250 processor for wired/wireless networking IP solutions

Posedge chose the eSi-3250 over alternative solutions due to its scalability, programmability, low power consumption and competitive licensing model.

“Standardizing on the eSi-3250 will help ensure that our wired/wireless networking IP solutions are always commercially competitive both from a technical and cost perspective,” said Chakra Parvathaneni, Vice-President of Marketing for Posedge. “Of the three processors we evaluated, only the eSi-3250 exhibited the combination of functionality and flexible licensing that we needed to take our ambitious product development plans forward. EnSilica even created a special version of the eSi-3250, with the option to switch the caching capability on and off, giving us extra flexibility.”

Posedge uses the eSi-3250 processor core, which delivers a Dhrystone MIPS performance of up to 1.41 DMIPS per MHz, in both single and challenging, mixed-mode multicore configurations to provide scalable performance and address different markets including those for Wired Packet Processors, Wireless Packet Processors, Security Protocol Processors and Wireless LAN MAC Controllers.

Posedge’s latest solution to use the eSi-3250 is an innovative 12-core Wireless Packet Processor for application-aware WLAN access points and LTE basestations that not only delivers a 10x performance improvement over existing solutions but also provides application level value added features. The eSi-3250 has also been successfully deployed in a 7-core Residential and SMB Gateway solution, dual core WLAN upper and lower MAC controller processor, PON Gateway and TCP Offload Engine.

The eSi-3250’s configurability enables Posedge to optimize the processor for different target applications including, for example, an ultra-low gate count version with just 16 registers used in its multi-core wired/wireless packet processors, through to a full-featured 32 register version with single cycle multiplier for its dual core WLAN solution. The eSi-3250 also includes configuration options to accelerate various bit field operations, such as fast insertion and extraction, which are useful when processing network protocol headers.

“Posedge’s decision to standardize on the eSi-RISC family for its wired and wireless networking solutions proves that it performs better than alternative embedded processor cores even for the most demanding multicore and high performance networking applications,” said Ian Lankshear, Managing Director of EnSilica.

Both EnSilica and Posedge are exhibiting at DAC 2012 in San Francisco (Moscone Center, 3-7 June 2012). EnSilica can be visited on Booth 2827 for discussions on its comprehensive IC design services and complete portfolio of embedded IP, including a highly configurable 16/32 bit embedded processor called eSi-RISC, the eSi-Comms range of communications IP and eSi-Crypto encryption IP. Posedge (Booth 2802) will be demonstrating its use of the eSi-3250 in its 7-core Residential and SMB Gateway solution.
