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 synchro-

nous port. Operations may occur on both ports simulta-

neously; the port with the highest priority will gain access

first if both ports require a read or write into the CAM

array simultaneously.

Multiple MUAA RCPs may be chained transparently to

provide deeper memory. No software configuration is

necessary. Each MUAA RCP detects where it is in the

chain from the chaining pins on the previous device. A

CAM memory and the number of CAMs chained. All

operations to the chained CAM are totally transparent. No

individual device selection or addressing is required.

The MUSIC MUAA RCP has aging, auto-aging, and

learning functions. All entries have a 9-bit time stamp and

may be marked as static to prevent the aging function from

deleting them. When auto aging is enabled it may be

configured to have higher or lower priority access than the

ports.

Two internal virtual queues of learned and aged entries are

available. As entries are learned or aged out they are

tagged as such and may be read from the device through

either of the ports. This feature enables simple host

management of aged out and learned entries.

The synchronous interface consists of 32-bit wide input

and output ports, both of which may be configured as 16

bits. The data is multiplexed into and out of the CAM and

RAM associated data field. Where input or output data is

wider than the port, it is loaded or unloaded in multiple

cycles starting with the least significant word. Internally

the device is pipelined; once an operation is started on the

synchronous port the next operation may be loaded and the

results of the previous operation unloaded, thus

maximizing device throughput.

IEEE Standard. 1149.1 (JTAG) testability is implemented

providing BYPASS, SAMPLE/PRELOAD, EXTEST,

CLAMP, and HIGH-Z functions.
