Abstract

A diagnostic system for a digital signal processor, having an input module, an output module and a plurality of successive processing modules defining a signal processing path, monitors various internal test points within each module. Any one of the test points may be connected to a diagnostic bus. The output of the diagnostic bus may be appropriately modified and input to the output module in lieu of the digital signal from the last processing module to provide a diagnostic display.
