A Method of Interprocessor Communication for a Multiprocessor Environment

An efficient method of interprocessor communication between a Digital Equipment Corporation LSI-11 minicomputer and an Intel 8085 microprocessor has been developed for a multiprocessor environment. In this method, which optimizes the handling of transactions between the two processors, an LSI-11 minicomputer interrupts the execution of the 8085 microcomputer under hardware control to place data directly in 8085 memory. Details of hardware implementation and interprocessor communication blocks are presented.
