A multiprocessor with replicated shared memory
Sigurd L. Lillevik, John L. Easterday · 1983
A multiprocessor includes five 8086 microprocessors interconnected with replicated shared memory. Such a memory structure consists of a set of memories, one for each processor, with identical contents. This minimizes read interference since each processor simply accesses its own private copy of the shared memory. To ensure shared memory integrity, write requests transfer data over the MULTIBUS to all copies in parallel. Overall, replicated shared memory structures provide improved concurrency.
