Source level debugger for debugging source programs

摘要

A source-level debugger debugs a source program for computers using a pipeline control method. The debugger includes a not-yet-processed instruction analyzing unit for analyzing each of instructions including not-yet-process stages in a pipeline when execution of a source program is halted (or suspended) or terminated, and for acquiring information on an internal state of the pipeline. A user interface unit displays the information on the internal state of the pipeline acquired by the not-yet-processed instruction analyzing unit in a predetermined display form on the screen of a display unit.
