Cache block size计算
WebNov 10, 2013 · Cache的大小(Size)可以如下计算得出，即Data Block中存放字节的数量和Cache中Data Block数量的乘积。 尽管Tag和Flag占有一部分的空间，但是我们在计算cache大小的时候并没有考虑。 一个有效的物理内存地址(Memory Address)被分为如下三个 … Web—We want the size of disk, but the performance of memory. The design of virtual memory systems is really motivated by the high cost of accessing disk. —While memory latency is ~100 times that of cache, disk latency is ~100,000 times that of memory. Hence, we try to minimize the miss rate: —VM “pages” are much larger than cache blocks.

WebMay 13, 2024 · The offset fields can be calculated using the information about the block size. A cache block is the basic unit of storage for the cache. For these set of problems the offset should be able to index every byte from within the cache block. offset bits = log2(block size) Calculating the number of bits for the cache index WebFeb 11, 2024 · 假设您有block_size行的sets组。 可以在tag：index：offset中拆分地址，其中log2(BLOCK_SIZE)位用于偏移，log2(SETS)位用于索引，其余部分用于标签。 您可以像这样计算log2：

Web0 前言这其实是对参考文献的一些总结和翻译，有一些内容和原文的顺序不一致，另外就是我的翻译水平不高，一些用词可能不准确。本来想大部分都翻译的，不过后面一些看起来有点迷糊，而且发现其实和我本意（对Cache多了解一些，优化代码）相差已经比较大了，就只翻译了前面的一部分，后面 ... WebThe index for a direct mapped cache is the number of blocks in the cache (12 bits in this case, because 2 12 =4096.) Then the tag is all the bits that are left, as you have …
WebIn a nutshell the block offset bits determine your block size (how many bytes are in a cache row, how many columns if you will). The index bits determine how many rows are in each set. The capacity of the cache is therefor 2^(blockoffsetbits + indexbits) * #sets. In this case that is 2^(4+4) * 4 = 256*4 = 1 kilobyte.
