Abstract
The present invention incudes a searching circuit which sequentially accesses a plurality of peripheral computers to receive requests for access by these computers to a principal memory normally occupied by a principal computer. The searching circuit determines the identity of the requesting computer and passes the request on to a decision circuit which receives information from the principal computer and the peripheral computers as to the state of occupancy of the access bus to the principal memory. If the bus is not occupied and the principal computer does not require use of the principal memory, the request is granted by the decision circuit.
