ABSTRACT:
The invention relates to a multi-microcomputer system employing a direct memory access controller for direct memory access. The data buses and address buses of the several microcomputers are interconnected by means of bus separator stages which normally isolate the buses, but enable the buses to communicate with each other during data exchange between the read-write stores of the individual microcomputers. The microprocessors are switched into their HOLD state during data exchange, and the data exchange is effected via the DMA controller which is supplied with the address zones of the source and destination by a designated microcomputer. In order to increase operational reliability, two or more multi-microcomputer systems, each containing a DMA controller, can be connected in parallel.
