Abstract
A performance monitor implementing a plurality of counters counts several events to provide an instruction fetch bandwidth analysis, a cycles per instruction (CPI) infinite and finite analysis, an operand fetch bandwidth analysis, an instruction parallelism analysis, and a trailing edge analysis. Such analyses are performed on the performance of a data processing system in order that the designer may develop an improved processor architecture.
