Enhancing Cache Performance Based on Improved Average Access Time

Abstract: A high performance computer includes a fast processor and millions bytes of memory. During the data processing, huge amount of information are shuffled between the memory and processor. Because of its small size and its effectiveness speed, cache has become a common feature of high performance computers. Enhancing cache performance proved to be essential in the speed up of cache-based computers. Most enhancement approaches can be classified as either software based or hardware controlled. The performance of the cache is quantified in terms of hit ratio or miss ratio. In this paper, we are optimizing the cache performance based on enhancing the cache hit ratio. The optimum cache performance is obtained by focusing on the cache hardware modification in the way to make a quick rejection to the missed line’s tags from the hit –or miss comparison stage, and thus a low hit time for the wanted line in the cache is achieved. In the proposed technique which we called Even-Odd Tabulation (EOT), the cache lines come from the main memory into cache are classified in two types, even line’s tags and odd line’s tags depending on their Least significant Bit (LSB), This division is exploited by EOT technique to reject the miss match line’s tags in very low time compared to the time spent by the main comparator in the cache, giving an optimum hitting time for the wanted cache line. The high performance of EOT technique against the familiar mapping technique FAM is shown in the simulated results.
