Design of an MS-DOS PC program profiler

Despite the popularity of the MS-DOS based PC and its compatibles, there have been few efforts at developing comprehensive program profilers for it. As a consequence, detailed instruction level usage studies of the PC have been difficult to conduct in the past. Existing profilers are unable to capture all the activity caused by the execution of a program. The design and implementation of a program profiler capable of capturing all processor initiated activity on the MS-DOS based PC are discussed, along with measurements made on sample application programs
