Abstract
A method and apparatus for determining the internal state of a processor without disturbing the operational environment of the processor employs a two phase process. In the first phase, external signals produced by the processor in the execution of a known program are monitored and recorded for subsequent analysis. In the second phase, the recorded information is analyzed in the light of the known characteristic of the processor, the program it was executing, and the signals recorded during the first phase. The internal state of the processor is thereby determined after the execution of each instruction. In addition, provisions are made for the specification of breakpoints, and the examination of simulated status of the processor on the occurrence of the breakpoints.
