ABSTRACT:
An improved real-time debugger accommodates high level language computer programs containing dynamic local data and process context switches. Information thus acquired is used to deduce the stack frame pointer. Inputs and outputs of a target processor are tapped to capture key instructions, particularly indicating context switches. A local tag memory in the debugger stores images of stack frames during context switches.
