Abstract
A multiprocessor microcomputer system having two or more substantially independent processors each of which has its own bus-type interconnection structure, and a shared memory accessible by any of the processors without interferring with the proper operation of the other processors. Controlled access to the memory by connecting the memory to the processor requesting access when only one such request is present and to the last processor to have received access when more than one request is received simultaneously allows autosynchronous operation, automatic selection of priority and high speed of operation.
