Data processing unit and data processing system comprising a plurality of such data processing units

摘要: In such a multi-processor system, master unit may be connected to number of slave units each programmed carry out particular function, and in turn these as its own set units, again perform function; the whole system being co-ordinated controlled by original unit. This disclosure relates modular data processing adapted form part comprising plurality master-slave relationship. Each comprises control section responsive instruction execution programme stored therein switch an idle mode on completion execution, internal memory including area read/write memory: computation for performing calculations accordance with instructions during which it can access memory; interface means through processor one or more monitor control, memories while is executing programme, thus monitored controlled, have accessed.
