The quality of functional testing of supercomputer

application often requires analyzing the interaction of the appli-

cation and the underlying architecture. In this report, we incorpo-

rate some performance counters in the minMIPS which monitor

a variety of processor events such as pipeline stalls,branch

predictions and memory access. We fi rst explain how proposed

method implemented.We then describe how the performance

counters can increase the test coverage for functional testing

of the microprocessor.And fi nally we reported the result of both

tests results with and with out performance counter.
