Abstract
The invention provides a system debugger for monitoring and controlling the operation of the multiprocessor. The debugger includes a view planning element that responds to operator input for generating a view signal specifying a subset of the first set of characteristics to be monitored. Likewise, a bundle planning element responds to operator input for generating a bundle signal specifying which functional units to be monitored. During operation of the multiprocessor, a runtime element monitors the operation of at least the functional units specified by the bundle signal to generate an output signal (e.g., for display on the user's monitor) representing values of the subset of characteristics specified by the view signal. The runtime element includes functionality for determining, for each of the specified functional units, which of its characteristics are in the specified subset. For those that are the runtime element generates the output signal to include subsignals representing the value of those specified characteristics. For that those are not, the runtime element generates the output signal to include a subsignal indicating the inapplicability of that characteristic to that functional unit.
