METHOD AND APPARATUS FOR SOFTWARE DEBUGGING

A software debugging analyzer nonintrusively acquires data concerning the execution of software on a real-time basis. Low-level event recognition is accomplished with programmable comparators, whose outputs are fed to high-level recognition comparators to define complex events. Dynamic recognition is provided by recognition cmparators programmable on a real time basis as variables are actuated. Acquired data is stored in memory in either a sequential or random access mode. A microprocessor translates high level commands into event constructs and processes the acquired data into a format suitable for display to a user.
