Data Sheet
MUAC Routing CoProcessor (RCP) Family
APPLICATION BENEFITS
Longest Prefix Match searches of IPv4 addresses
28 million IPv4 packets per second supports up to 18 Gb Ethernet or 7 OC-48 ATM ports at wire speed
Exact match on MAC addresses
Processes DA and SA within 190 ns, supporting three ports of 1 Gb or 34 ports of 100 Mb Ethernet at wire speed
Mixed mode L3 and L2 single search engine for two ports at 1 Gb or 29 ports of 100 Mb Ethernet at wire speed
Directly addresses external RAM containing associated data of any width
Hardware control states directly address memory and registers; Instruction and Status registers for optional software control
DISTINCTIVE CHARACTERISTICS
4K and 8K x 64-bit words 32-bit ternary or 64-bit binary compares 35 ns deterministic compare and output time 32-bit Data I/O port 16-bit Match Address Output port Address/Control bus directly controls device
