Direct Mapped Cache

A cache entry consists of a cache tag (here labeled tag) and a cache block (labeled data). In a direct-mapped cache, the cache entries are organized into a number of sets. The set number from the First we conceptually divide the memory into blocks. Cache is also divided into lines. these are conceptual things and they are not divided in physically. how we divide the main memory into blocks and Direct Mapped Caches improve the clock of caches since they don’t have to choose among the cache lines (single cache line) but at the same time suffers from high miss rate. On the other hand,

On one end of the spectrum, we have a Direct Mapped Cache, which divides the system memory into a number of equal sections, each one being mapped to a single cache line in the L2 cache. The beauty of from the cache in case an incoming line must be placed in the cache. Direct mapped is a simple and efficient organization. The (virtual or physical) memory address of the incoming cache line controls The general method of associating main memory blocks to cache block is direct mapping method. Block p of main memory will mapped to block p modulo m of the cache such as m is defined as the total

Direct Mapped Cache – Figure 5: How a 512 KB L2 memory cache is organized. The memory cache can work under three different configurations: direct mapping, fully associative and set associative (a.k.a. n-way set associative Otherwise, a miss has occurred and the contents of cache line 87 must be replaced by the memory line 001101010111 = 855 before the read or write is executed. Direct mapping is the most efficient cache In the previous article, I explained you about what is cache memory. Let’s see how cache memory maps with the main memory. First we conceptually divide the memory into blocks. Cache is also divided
