ABSTRACT:
A virtual monitor controller includes a data storage device coupled to receive and output data; an instruction storage device coupled to receive and output instructions; a status storage device coupled to receive and output status data; and a mode storage device coupled to receive and output mode data. The virtual monitor controller is included in a debugger/monitor controller. A debugger/monitor system comprises a host system; the debugger/monitor controller; and a digital processor. Preferably, the controller is coupled between the processor and IC logic. A method of operating a virtual monitor comprises the steps of intercepting an instruction fetch from a microprocessor; downloading instructions from a host computer; and operating the microprocessor with the instructions. Preferably, the instructions are sequentially downloaded.
