Cypress Semiconductor Corporation’s (Cypress’s) CYNSE70128 network search engine (NSE) incorporates patent-pending
Associative Processing Technology™ (APT) and is designed to be a high-performance, pipelined, synchronous, 64K-entry NSE.
The CYNSE70128 database entry size can be 72 bits, 144 bits, or 288 bits. In the 72-bit entry mode, the size of the database is
64K entries. In the 144-bit mode, the size of the database is 32K entries, and in the 288-bit mode, the size of the database is 16K
entries. The CYNSE70128 device is configurable to support multiple databases with different entry sizes. The 36-bit entry table
can be implemented using the Global Mask Registers (GMRs) building-database size of 128K entries with a single device.
The NSE can sustain 100 million transactions per second when the database is programmed or configured as 72 or 144 bits.
When the database is programmed to have an entry size of 36 or 288 bits, the NSE will perform at 50 million transactions per
second. The CYNSE70128 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 perfor-
mance and features of the CYNSE70128 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 3968K entries specifically for environments that require large network
policy databases. The block diagram for the CYNSE70128 device is shown on page 10.
