Abstract
A network processor includes a cache and a several groups of processors for accessing the cache. A memory interconnect provides for connecting the processors to the cache via a plurality of memory buses. A number of trace buffers are also connected to the bus and operate to store information regarding commands and data transmitted across the bus. The trace buffers share a common address space, thereby enabling access to the trace buffers as a single entity.
