Performance of an embedded optical vector matrix multiplication processor architecture

Abstract

An embedded architecture of optical vector matrix multiplier (OVMM) is presented. The embedded architecture is aimed at optimising the data flow of vector matrix multiplier (VMM) to promote its performance. Data dependence is discussed when the OVMM is connected to a cluster system. A simulator is built to analyse the performance according to the architecture. According to the simulation, Amdahl's law is used to analyse the hybrid opto -electronic system. It is found that the electronic part and its interaction with optical part form the bottleneck of system.2 Embedded architecture of ODSP Fig. 2 shows our architecture of ODSP. The ODSP is mainly composed of OVMM, caches, VMM registers, control unit
