Accurate instruction fetch and branch prediction is increasingly important on today’s wide-issue architectures. Fetch prediction is the process of determining the next instructi...
In this paper, we use the CoDeL hardware design platform to analyze the potential and performance impact of power gating individual registers. For each register, we examine the per...
Interpreters designed for efficiency execute a huge number of indirect branches and can spend more than half of the execution time in indirect branch mispredictions. Branch target...
As the issue rate and depth of pipelining of high performance Superscalar processors increase, the importance of an excellent branch predictor becomes more vital to delivering the...
Branch prediction accuracy is a very important factor for superscalarprocessor performance. The ability topredict the outcome of a branch allows the processor to effectively use a...
