Data cache hits cannot easily be accounted for in instruction and
BFFFO and CHK2). The effect of a data cache hit on such CCop's has
been ignored for computational purposes.
RMC cycles (e.g., TAS and CAS) are forced to miss on data cache
reads. Therefore, a data cache hit has no effect on these instructions.
It is helpful to include the number of operand reads and writes along
puting the effect of data cache hits on execution time.
