20mbit quad-search content addressable memory 360-msps tcam maximizes multi-layer packet processing in routers and switches switches and routers must deliver bandwidth-hungry services such as voice over ip (voip), iptv, video on demand (vod), and wireless 3g/4g with the appro - priate quality of service (qos) levels. to create the platforms necessary to optimally manage large amounts of network traf c quickly and effectively, system designers are increasingly relying on advanced ternary content address - able memory (tcam) devices for performing ultra-fast data packet searches. the new renesas R8A20410BG quad-search tcam has been developed to address the stringent requirements of high data throughput combined with deep packet inspection (dpi) for multi-service routers and switches. this 20mbit device can make deterministic packet searches at speeds up to 360 mega searches per second (msps)/table ? the industry?s highest packet look-up performance. allows 40g+ rates operating at 360mhz, the quad-search tcam chip enables data transfer rates of 40gbps and higher. search bit lengths can be set to 40, 80, 160, 320, 480, or 640 bits. the device also has a multi-bank architecture with four paral - lel, independently operating search engines which signi cantly boosts look-up performance, while supporting a wide range of network applications. to accommodate very large routing tables, the R8A20410BG allows expansions up to 40-mbit density through cascade connections. incorporating a full-custom con gurable cam array with an easy-to-use interface, the quad-search tcam rede nes the state of the art in network search technology. the chip is planned to be interoperable with cavium networks? octeon ? 58xx multi-core processors, as well as xelerated?s hx family of network processors. features & bene?ts 20mbit density supports large routing tables and enables low-cost, low-power, more reliable system designs 360 million searches per second (msps) per table delivers the industry?s highest packet look-up performance for 40g applications and beyond 40-, 80-, 160-, 320-, 480-, or 640-bit search key-width support provides ?exible search conditions that support multiple search-key con?gurations multi-device cascading allows the tcam array capacity to effectively be doubled to 40mb by connecting two identical quad-search tcams together using the cascade interface signals sub-core pre-charge technology uses patented design techniques to greatly reduce power consumption, even during high-speed operation compact package 576 fc-bga (27mm x 27mm, ?ip-chip type) applications enterprise switches and routers metro switches and routers core switches and routers edge switches and routers 3g/4g mobile access platforms ipv4 / ipv6 packet forwarding layer-4 to layer-7 deep packet inspection internet protocol security (ipsec)
