An orthogonal multiprocessor for ATM switch system

Asynchronous Transfer Mode (ATM) presents an evolutionary path to provide high bandwidth services and integrates many existing networks into a common architecture. However, ATM should provide native packet services, yet the cell relay method of ATM cannot efficiently fit packet service, especially in heavy traffic. In this paper, we employ an OrthogonaI Multiprocessor (OMP) architecture using Dual-Port memory to enhance the CPU power and eliminate the bus contention problem. The proposed architecture called EOMPA (Enhanced OMP Architecture) also applies a multi-level switch method to fit the multifarious traffics.
