Posedge Inc. enhances its multi-port Gigabit Ethernet Switch Sub-System IP to integrate to ASICs and FPGAs offering its L2+ switch with features such as IEEE-1588 support for time stamping, A/V bridging, EEE support for Gigabit Ethernet, priority-based flow control and enhanced VLAN support.

The Multi-Port Gigabit Ethernet Switch Sub-System IP is based on Wire-speed Secure Packet Processor (WSP) architecture that is scalable from 2-port 10/100Mbps Switch to 8-Port 10/100/1000Mbps Switch.

The firmware is also enhanced to support L3 Extensions, Advanced Filtering, Snooping, and enhanced API for additional programming and configuration. Similar to the previous version, the software is backed by a tool chain capable of Multi-Core debug and validation.

In addition the architecture is scalable from few 100Mbps to 16Gbps with flexibility in deployment with options like CAM based or SRAM based MAC Tables. The features supported by the L2+ Ethernet Switch are targeted for Audio/Video distribution, Power Optimisation, and end-to-end performance in adverse environments. "WSP Architecture provides very high levels of adaptation with programmable processors for classification, packet editing and functions like QoS in hardware", added Chakra Parvathaneni, VP Marketing, Posedge Inc.

Posedge provides, as part of the IP licensing package reference drivers, Management Processor code, and extensive customer support. The IP package consists of Verilog RTL code; self-checking OVM based test bench/test cases and elaborate documentation with functional coverage results. Posedge also offers a suite of design services for customisation and integration of the IP cores into customer's ICs or FPGAs for prototyping.

The L2+ Switch is a completely self-contained IP with proprietary bus for optimal throughput and can operate in Un-Managed Switch or Managed Switch modes. It provides flexible performance that scales with internal memory and processors and is optimal when silicon area and throughput are important and offers exceptional security and flexibility for your business' network.
