SAN JOSE, Calif. -- Cypress Semiconductor (NYSE:CY), the industry leader in high-performance Network Search Engines (NSEs), today announced sampling of its 256K IP entry (9 Mbit) NSE. The CYNSE70256 has very low power consumption due to its 1.5V core voltage and has performance as fast as 83 million searches per second (MSPS). This device is ideal for applications requiring large routing tables and wirespeed processing at OC-48 (2.5 Gbps), OC-192 (10 Gbps), and beyond. Internet traffic growth, as well as the increasing number of services offered over the web, has created a demand for very large entry devices such as the CYNSE70256, which can perform layer 3-7 searches at high line rates of OC-48, OC-192 and beyond. The CYNSE70256 has the variable entry-width capability (34 bits - 288 bits) within its content addressable memory (CAM) array to accommodate a broad range of searches from simple IP forwarding to complex multi-layer quality of service (QoS) filtering. The CYNSE70256 is a ternary (bit-maskable) device that allows for optimal implementation of the Longest Prefix Match (LPM) routing algorithm. It also provides global masks for high-performance subfield searches. "Cypress's CYNSE70256 NSE provides the networking infrastructure market with an excellent solution for addressing the critical demand for high-speed packet processing in areas of dense Internet traffic such as the core of the network," said Bob Wheeler, senior analyst at The Linley Group. "Cypress's leadership in this area can be attributed to its world-class engineering capability and an in-depth knowledge of the networking space." Cypress Semiconductor Corp.
