Cypress launches design support for Sahasra search engine
24 March 2004
Cypress Semiconductor Corp has unveiled extensive hardware and software design tools for its Sahasra 50000 network search engine (NSE).
The Cynapse design tools enable designers of networking control-plane software and packet processors to begin development of systems with Cypress's Sahasra 50000 NSE.
The Sahasra device is the industry's first algorithmic search engine to combine a ternary content addressable memory (TCAM) with the increased routing capacity of an algorithmic search solution.
The Cynapse software support includes the table manager, API, and device model that allow system software designers to begin development of critical control plane software in advance of silicon availability. By providing a production-ready table manager source code and high-level API, Cypress enables customers to minimise time-to-market and software development costs.
The Cynapse toolset also includes the Sahasra Verilog hardware model, which allows designers to migrate to the higher forwarding table capacity of Sahasra with minimal impact on their packet processor, whether it is an ASIC or FPGA.
"The Sahasra 50000 NSE combines our patented search algorithms and NSE technology, providing customers with the optimal forwarding solution by delivering performance, power, and scalability that is beyond the reach of algorithmic search systems using external DRAM or SRAM," said Vivek Pendharkar, a spokesman for Cypress. "Now we've teamed the device with the critical software and hardware support that system designers need early in the design cycle, well before silicon."
The Sahasra 50000 NSE family is able to store 1.5 million IPv4 routes in a single chip and addresses the search needs of systems requiring large forwarding tables, such as core routers and Layer 3 switches. It is available in two densities, supporting 1.5 million or 650K IPv4 routes. The device is scheduled to sample in Q3 2004.
