PARALLEL SIGNAL PROCESSOR

摘要

PURPOSE:To perform picture signal processing on real-time basis by writing a signal alternately in memories of two systems consisting of plural memory blocks, and reading their contents and outputting them after serial conversion. CONSTITUTION:Input data inputted to a register 10 is inputted to a memory 2 or 3 through a latch 12 and a multiplexer 13. The memory 2 consists of memories 2-1-2-21 and input picture data is inputted to the memories 2-1-2-21 in parallel. In case of the memory 3 it is the same. Picture data written in the memory 3 is read out in parallel while the input picture data is written in the memory 2, and sent in series to a processor 1 through a parallel/series conversion register 7. This register 7 reads the contents of the memory at a low speed which is a submultiple of that of the instruction cycle of a processor 1. The contents of the register are inputted to the processor, one by one in every instruction cycle.
