Parallel processing method for use with graphics processor

Abstract

A parallel processing method for use with a graphics processor wherein graphics processing is performed by each of configured command processors efficiently in a distributed manner, with a host CPU remaining unaware of the number of command processors. Each command group of a variable length from a host CPU is distributed from an FIFO queue to a plurality of parallelly arranged command processors for parallel processing through any free one of input FIFO queues corresponding to the command processors. Upon command group distribution, an identical serial number is added as a command group serial number to the commands constituting the same command group. The results of processing of individual graphics commands by the command processors are collected via output FIFO queues, which also correspond to the processors, in the order of the command group serial numbers added to the commands before the processed results are graphically drawn.
