WebIn a two-way set associative cache, we might group the cache into two sets: indexes 0 and 1 form one set—set 0—and indexes 2 and 3 form another—set 1. So we could use the remainder of the main memory index modulo 2, and cache line 0 would be mapped to either cache index 0 or cache index 1. See Table 2.1.

WebA set-associative cache is characterized by the number of banks or ways used, giving an n-way set-associative cache. A set is formed by all the blocks (one for each bank) that share the same index. Each set is implemented with a direct-mapped cache. A cache request is broadcast to all banks simultaneously.

(So log-base-2 of the block-size.) The index-bits are used to decide which cache-line to look at (so needs to be log-base-2 of the number of cache lines.) The tag-bits are whatever is left over, and need to be compared to the tag on the cache line. cory felder

WebMay 28, 2014 · Because the index cache is filled with index pages, for optimum use of storage, set the size of the index cache to be a multiple of the size of the index page (8 KB). Data File Cache (Direct I/O only): If possible, set the data file cache to equal the size of the stored data, which is the combined size of all ess*.pag files. Otherwise, the data ... 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.
