Nonvolatile SRAMs expand to 8Mbit
New 2 and 8Mbit nvSRAMs feature access times as low as 20ns, infinite read, write and recall cycles, and 20-year data retention.
Design tool bridges high and low levels
Integrated design environment includes both code-free and high-level-language programming modes in one package.
It maximises look-aside (LA-1) bus bandwidth and simplifies overall search-system management.
When used in conjunction with Cypress's Ayama NSE10000 family of network search engines (NSEs), the Vichara 81000 enables as many as 266 million searches per second.
The Vichara 81000 relieves network processors (NPUs) and ASICs of routing lookups and policy-resolution functions.

A microdongle that is roughly the size of a US dime uses the fully integrated CYRF69213 PRoC LP device to deliver low-power wireless connectivity to Darfon's mice.
By offloading these search-related instructions, the Vichara 81000 increases 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.
"Complexity of the linecard search subsystem is increasing with the advent of services such as quality of service (QoS), policy and billing", said Jag Bolaria, senior analyst at the Linley Group and co-author of A Guide to Classification and Traffic Management
