ABSTRACT:
A data processing system includes a central processing unit (CPU) (20), a peripheral bus (32), and an input/output (I/O) coprocessor (38). The CPU (20) and the I/O coprocessor (38) are coupled to the peripheral bus (32). The I/O coprocessor (38) has a plurality of front-end channels (50) for receiving a time-base, and in response, for providing a time-base reference for input signals and generating output signals using the time-base reference. A back-end processor (80) controls operation of the plurality of front-end channels (50) in response to executing instructions. A visibility bus (40), coupled to the back-end processor (80), is for providing visibility of the internal registers of the back-end processor (80) independent of the CPU (20). The visibility is provided for development of the instructions executed by the back-end processor (80).
