Cache block size計算
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 … WebThe origin is divided up into blocks of a fixed size. This block size is configurable when you first create the cache. Typically we’ve been using block sizes of 256KB - 1024KB. The block size must be between 64 sectors (32KB) and 2097152 sectors (1GB) and a multiple of 64 sectors (32KB). Having a fixed block size simplifies the target a lot.

WebFeb 6, 2024 · A 32-bit processor has a two-way associative cache set that uses the 32 address bits as follows: 31-14 tags, 13-5 index, 4-0 offsets. Calculate : The size of the cache line in number of words; The total cache size in bits; I do not understand how to solve it, in my slides there is almost nothing on the set associative caches. Solutions : WebBut as block size increases, the number of sets in a fixed-size cache decreases, increasing the probability of conflicts. Figure 8.18 plots miss rate versus block size (in number of bytes) for caches of varying capacity.
