A MULTI-PROCESSOR COMPUTING SYSTEM AND ITS TASK ALLOCATING METHOD

摘要

A multi-processor computing system is disclosed. The multi-processor computing system comprise a host processor, a global memory and at least one processing units, wherein the multi-processor computing system further comprising: a micro task sequencer, comprising a task acquisition device and a task scheduling device, wherein the task acquisition device is configured to fetch a command including micro task descriptions from the global memory if the micro task sequencer is capable to accommodate further commands, and the task scheduling device is configured to dispatch each micro task instruction defined by each of the micro task descriptions to one of the at least one processing units, so that the indicated processing unit can execute the micro task instruction, and the task scheduling device is further configured to detect the completion of all the micro tasks in the command and notify the host processor of the completion, wherein the processing unit can access the global memory by itself or by another of the at least one processing units.
