Description
GENERAL DESCRIPTION
The MUSIC MUAA Routing Co Processor (RCP) family consists of 80-bit wide content-addressable memories (CAMs), available in depths of 2K and 8K words. The CAM/RAM associated data partition is programmable from 32 bits of CAM and 48 bits of associated data, to 80 bits of CAM and 0 bits of RAM. The MUAA RCP can perform normal routing functions such as search, insert, and delete on single entries and can age multiple entries simultaneously. In addition, there is a learn instruction, particularly useful in networking applications. For maximum flexibility all the operations may be performed either through the processor port or through the synchronous port. Operations may occur on both ports simultaneously; the port with the highest priority will gain access first if both ports require a read or write into the CAM array simultaneously.
The synchronous interface consists of 32-bit wide input and output ports, both of which may be configured as 16 bits. The data...
