Abstract: A system for direct interprocessor communication in a multiprocessor data processing environment. The system utilizes conventional direct data transfer means and existing I/O port instruction capabilities available on most microprocessors. A destination processor requiring data from one of a source processor's internal registers generates a unique address which specifies the register containing the required data. The address is sent to the data transfer means, causing the direct transfer of data from the designated source processor internal register to the destination processor. Specific circuitry to accomplish this direct data transfer function is described.
