Recent studies have concluded that little parallelism (less than two operations per cycle) is available in single instruction streams. Since the amount of available parallelism should influence the design of the processor, it is important to verify how much parallelism really exists. In this study we model the execution of the SPEC benchmarks under(More)
Deeply pipelined, superscalar processors require accurate branch prediction to achieve high performance. Two-level branch predictors have been shown to achieve high prediction accuracy. It has also been shown that branch interference is a major contributor to the number of branches mispredicted by two-level predictors.This paper presents a new method to(More)
