阅读更多关于 Cache Memory Optimization Array Transpose: C

typedef int array[2][2]; void transpose(array dst, array src) { int i, j; for (j = 0; j < 2; j++) { for (i = 0; i < 2; i++) { dst[i][j] = src[j][i]; } } } src array starts at address 0 and the dst array starts at address 0x10. L1 data cache, direct map, write-allocate, 8 byte block size. cache total size is 16 data bytes. What is the hit or miss on each entry of src and dst array? The answer is: src: [0][0] -> miss, [0][1] -> miss, [1][0] -> miss, [1][1] -> hit dst: [0][0] -> miss, [0][1] -> miss, [1][0] -> miss, [1][1] -> miss If the cache total size is 32 data bytes, the answer is: src: [0]
