Since target applications in embedded systems are limited, we can optimize its cache configuration. A very fast and exact cache simulation algorithm, CRCB, has been recently proposed. CRCB assumes LRU as a cache replacement policy but FIFO- or PLRU-based cache is often used due to its low hardware cost. This paper proposes exact and fast L1 cache simulation algorithms for PLRU- or FIFO-based caches...
In recent years, the gap between the cycle time of processors and memory access time has been increasing. One of the solutions to solve this problem is to use a cache. But just using a large cache may not reduce the total memory access time. We can have an optimal cache configuration which minimizes overall memory access time by varying the three cache parameters: a cache set size, a line size, and...
