Stream processor including DMA controller used in data processing apparatus

摘要

In a stream processor, an input direct memory access circuit is adapted to receive a task command and task data in correspondence with a task from an external memory. A processor unit is adapted to receive the task command and the task data from the input direct memory access circuit and perform the task upon the task data in accordance with a task program designated by the task command. A direct memory access controller is adapted to load the task program from the external memory into the processor unit upon receipt of a task program load request from the processor unit.
