DATA PROCESSING CONTROL UNIT, METHOD FOR CONTROLLING DATA PROCESSING OPERATIONS AND DATA PROCESSING SYSTEM

摘要

A data processing control unit (10) for controlling two or more data processing operations SMI 1 ,SMI2. The data processing control unit (10) may include a control memory (13) in control data may be stored which represents information about access to a main memory by the two or more data processing operations. A control data controller (14) may be connected to the control memory (13). The control data controller (14) may include a control data controller input (140) for receiving an access request from one or more of the data processing operations. The control data controller may modify the data in the control memory upon receiving the access request. A process controller (15) may be connected to the control memory (12). The process controller may control at least a part of the data processing operations SMI1.SMI2 based on a comparison of data in the control memory (13) with a criterion. The process controller (15) may include a process controller input (150) for receiving the access request; and a process controller output (1510 for outputting a process control signal based on the comparison.
