Throughput analysis of cache-based multiprocessors with multiple buses

The performance of cache-based multiprocessors for general-purpose computing and for multitasking is analyzed with simple throughput models. A private cache is associated with each processor, and multiple buses connect the processors to the shared, interleaved memory. Simple models based on dynamic instruction mix statistics are introduced to evaluate upper bounds on the throughput when independent tasks are run on each processor. With these models, one can obtain a first estimate of the MIPS (millions of instructions per second) rate of a multiprocessor.<
