ABSTRACT:
Data pertaining to the operation of a signal-processing system are written in zones of a central read/write memory which are either permanently or temporarily allocated to respective peripheral units to be monitored and which are each divided into a plurality of phases accommodating multibit words. An interface unit, designed to read out the contents of one or more phases of a memory zone allocated to a chosen peripheral unit and to transfer them to a kinescope or a printer for visualization, includes a buffer store connected to the memory and controlled by a command circuit which responds to several selectors receiving the output signals of an address counter identifying the several memory zones and phases. In the case of temporary allocation, each peripheral unit has a three-word code entered in predetermined phases of the allocated zone which can thus be identified by one of the selectors of the interface unit.
