High performance, extremely low latency and highly configurable ternary content-addressable memory IP
Overview
tCAM-IP is a high performance, extremely low latency and highly configurable ternary content-addressable memory IP. tCAM-IP can make deterministic search at 200MSPS continuously speed with constant latency at 7 clock cycles. It can achieve matching/filtering performance at 200,000,000 packets per second over 40G/100G Ethernet. It is ideal for variant applications such as network packet filtering/forwarding, intelligent switch/router, deep packet inspection and network security application.
