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.
