Single-instruction multiple-data processor having dual-ported local memory architecture for simultaneous data transmission on local memory ports and global port - Patent US5361370(A)

Filed: Oct 24, 1991

Abstract

A single-instruction multiple-data video signal processor employs a dual-ported local memory architecture in each local memory including a dedicated port for transfers between the local memory and a global memory. A block transfer controller, in combination with the dedicated port, permit each access to the global memory by a datapath processor to be overlapped with its instruction processing, thus usually avoiding stalling of the video signal processor.
