Abstract
A Network Processor (NP) includes a controller that allows maximum utilization of the memory. The controller includes a memory arbiter that monitors memory access requests from requesters in the NP and awards high priority requesters all the memory bandwidth requested per access to the memory. If the memory bandwidth requested by the high priority requester is less than the full memory bandwidth, the difference between the requested bandwidth and full memory bandwidth is assigned to lower priority requesters. By so doing every memory access utilizes the full memory bandwidth.
