Abstract: Increasing the speed of cache simulation to obtain hit/miss rates en- ables performance estimation, cache exploration for embedded sys- tems and energy estimation. Previously, such simulations, particu- larly exact approaches, have been exclusively for caches which uti- lize the least recently used (LRU) replacement policy. In this paper, we propose a new, fast and exact cache simulation method for the First In First Out(FIFO) replacement policy. This method, called DEW, is able to simulate multiple level 1 cache configurations (dif- ferent set sizes, associativities, and block sizes) with FIFO replace- ment policy. DEW utilizes a binomial tree based representation of cache configurations and a novel searching method to speed up sim- ulation over single cache simulators like Dinero IV. Depending on different cache block sizes and benchmark applications, DEW oper- ates around 8 to 40 times faster than Dinero IV. Dinero IV compares 2.17 to 19.42 times more cache ways than DEW to determine accu- rate miss rates.
