CYNSE70064A General Description


Cypress Semiconductor Corporation's (Cypress's) CYNSE70064A network search engine (NSE) incorporates patent-pending Associative Processing Technology™ (APT) and is designed to be a high-performance, pipelined, synchronous, 32K-entry NSE.
The CYNSE70064A database entry size can be 68 bits, 136 bits, or 272 bits. In the 68-bit entry mode, the size of the database is 32K entries. In the 136-bit mode, the size of the database is 16K entries, and in the 272-bit mode, the size of the database is 8K entries. The CYNSE70064A is configurable to support multiple databases with different entry sizes. The 34-bit entry table can be implemented using the global mask registers (GMRs) building-database size of 64K entries with a single device.
The NSE can sustain 83 million transactions per second when the database is programmed or configured as 68 or 136 bits. When the database is programmed to have an entry size of 34 or 272 bits, the NSE will perform at 41.5 million transactions per second.
The CYNSE70064A device can be used to accelerate network protocols such as longest-prefix match (CIDR), ARP, MPLS, and other layer 2, 3, and 4 protocols.
This high-speed, high-capacity NSE can be deployed in a variety of networking and communications applications. The performance and features of the CYNSE70064A make it attractive in applications such as Enterprise LAN switches and routers and broadband switching and/or routing equipment supporting multiple data rates at OC-48 and beyond. The NSE is designed to be scalable in order to support network database sizes to 1984K entries specifically for environments that require large network policy databases.
