Cypress Semiconductor Corp. has announced the availability of 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 the Sahasra 50000 NSE. 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.

"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, Managing Director of NSEs for Cypress's Data Communications Division. "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."

To ensure that a customer's hardware and software development schedules are aligned, the Cynapse toolset includes the Sahasra Verilog hardware model. Because the interface of the Sahasra NSE is logically and electrically compatible with the company's Ayama 10000 family of NSEs, designers can migrate to the higher forwarding table capacity of Sahasra with minimal impact on their packet processor, whether it is an ASIC or FPGA.

Claimed by Cypress as the industry's first algorithmic search engine to combine the ease of use of a ternary content addressable memory (TCAM) with the increased routing capacity of an algorithmic search solution, the family of NSE uses advanced search algorithms and integrated SRAM to achieve cost per route and power of DRAM solutions.

Capable of storing 1.5 million IPv4 routes in a single chip, Sahasra 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.
