ABSTRACT:
An apparatus for and method of providing rapid communication between separately clocked system elements. A network interface module is used as the overall system control and communication interface to each of the separate system elements. Each of these system elements is controlled by a different and dedicated programmable micro-engine. A separate register located within and addressable by each of the micro-engines provides the basic data transfer path. Access by a micro-engine to the corresponding register is easily accomplished by firmware. The bit serial scan interface between the network interface module and each of the registers is controlled by the network interface module.
