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