Estimating the term…
The apparatus has a multiplicity of control modules which are assigned to a multiplicity of processing modules for driving purposes. These separate control modules are driven by a superordinate controller and are synchronized by a common synchronization unit on the basis of, by way of example, handshake lines and semaphores. The effect achieved by such an apparatus is that the transmission bandwidth between an external instruction memory and the large-scale integrated system can be reduced, and the total power loss can be lowered by intermittently disconnecting processing modules which are currently not needed. Furthermore, such an architecture supports the separate development of control programs for the individual control modules.
An apparatus for hierarchical and distributed control of programmable modules in large-scale integrated systems, comprising a multiplicity of control modules interchanging control information with a superordinate control unit and communicating through control lines to drive processing modules permanently assigned to respective said control modules, a synchronization unit connected to all said control modules via synchronization lines, a dedicated instruction cache memory allocated to each said control module, and whereby respective control modules are selectively connectible and disconnectible by said superordinate control unit, and/or said processing modules are selectively connectible and disconnectible by appropriate control signals on said control lines.
