Abstract
The central processing unit, which communicates with the real time memory, is controlled in accordance with the selected procedure and has an operating unit for providing the latter procedure. The central processing unit includes a block memory which can only be accessed by the operating unit. The communication centre provides information representing the selected procedure, and has means communicating with the operating unit to provide a partial address for the stored procedures, and further means addressed by the latter for providing the full address for the procedure, with an updating circuit for the information stored in the communication centre and in the block register. The selected procedure may be indicated and/or displayed.
