Abstract
A multiprocessor control system which has at least one main storage unit, a plurality of main storage control units, a plurality of processing units, and a control bus. Each processing unit is connected to the main storage unit through one of the main storage control units. When each processing unit transmits a request for access to at least one main storage unit, the processing units transmit the request to the main storage control units to which each processing unit is connected, and simultaneously, to all of the other main storage control units, through the control bus. All of the main storage control units process the request from the processing unit, synchronously, and execute a busy check control or the like. Data transmitted between each processing unit and an arbitrary one of the main storage units is transmitted only through the main storage control unit to which the processing unit is connected. By using this system, if units needing a high throughput are applied, the system can be controlled in a comparatively simple manner.
