Abstract
A system and method, operable on a general purpose computer, for debugging software that is to control a digital signal processor ("DSP") and a general purpose computer employing either the system or the method. The present invention is employable with either a real DSP or an emulated DSP. When the DSP is emulated, the system includes: (1) architectural display circuitry that displays an architecture of a particular DSP in a window on a display of the general purpose computer, the architecture including a graphical device layout and at least one field corresponding to a register of the DSP and (2) software simulation circuitry that employs a processor of the general purpose computer to simulate operation of DSP software and emulate operation of the particular DSP to cause the particular DSP to change states over time, the architectural display circuitry updating the at least one field to reflect changes in the states, the architectural display circuitry and the software simulation circuitry cooperating to allow a user to debug the software by visually inspecting the graphical device layout and the at least one field.
