SYSTEM AND METHOD FOR MEMORY MANAGEMENT WITHIN A NETWORK PROCESSOR ARCHITECTURE

The present invention discloses a system and method for balancing memory accesses to a low cost memory unit (shared central buffer) in order to sustain and guarantee a desired line rate regardless of the incoming traffic pattern. The memory unit may include, for example, a group of dynamic random access memory units. The memory unit is divided into memory channels and each of the memory channels is further divided into memory lines, each of the memory lines includes one or more buffers that correspond to the memory channels. The determination as to which of one or more buffers within a memory line an incoming information element is stored is based on factors such as the number of buffers pending to be read within each of the memory channels, the number of buffers pending to be written within each of the memory channels, and the number of buffers within each of the memory channels that has data written to it and is waiting to be read.
