摘要
Abstract
The average penalty of Level 1 Instruction Cache(Ll I-Cache) is simply quantified for the next level storage access time, this simple quantitative introduces large errors during analysis of performance bottlenecks. Aiming at the problem, this paper uses interval model to analyze what are the front-end factors that impact on the average penalty, and validate the analytical results through simulation experiments. Result shows that in addition to the next level of cache or main memory access time, fetch bandwidth, the size of the fetch queue, the LI I-cache miss rate, the branch misprediction rate and the program characteristic can impact on the average of LI I-Cache miss penalty.关键词
