The Vichara 81000 is claimed by Cypress Semiconductor Corp. to be the industry's first search supervisory coprocessor that enables packet processors to achieve 40Gbps throughput by offloading search-intensive processing and managing multiple searches.

The company also claims that when used in conjunction with the Ayama NSE 1000 family of network search engines, the Vichara 81000 reaches up to 266 million searches per second.

The Vichara 81000 operates at 266MHz, and relieves network processors (NPUs) and ASICs of routing lookups and policy-resolution functions to increase the packet processor's ability to perform other linecard functions, resulting in more processor headroom.

It also relieves packet processors of control-function management by providing direct connectivity and hardware features to perform out-of-band control updates for policing and aging functions, enabling the NPU/ASIC to process more packets per second at the same wirespeed.

The 484-pin BGA device can also interleave and execute multiple contexts in parallel for up to four packet processors supporting up to 64 contexts on each of its four ports. For LA-1 compliant NPUs - including those from Intel, AMCC, and IBM - the coprocessor's search offload translates into significantly higher efficiency for the LA-1 bus.

The Vichara 81000 (part number CYNCP81000) is priced starting at $250 in quantities of 1,000.
