Abstract
A parallel processing processor system includes multiple processor elements, a main memory, and a shared memory, whose latency with the processors is less than the latency between the main memory and the processors. Each of the multiple processor elements has a DSP (Digital Signal Processor) and an instruction cache. Firmware executed by the DSPs is transferred from the main memory to the shared memory and is shared by the DSPs. Updating of the instruction caches in the case where a cache miss has occurred is performed by, for example, copying, into the instruction caches, the content of the shared memory corresponding to an address accessed by a DSP.
