ABSTRACT:
A device control register controller for a processor block Application Specific Integrated Circuit (“ASIC”) core is described. Device control register slave blocks are coupled to the device control register controller and have access to device registers for a plurality of interfaces of the processor block ASIC core. A master device interface is for coupling at least one slave device external to the processor block ASIC core to the device control register controller. A slave device interface is for coupling a master device external to the processor block ASIC core to the device control register controller.
