You have a 1,024-byte direct-mapped data cache with 16-byte blocks. A structure is defined as: 1 struct my_struct { 2 int x; 3 int y; }; 6 struct my_struct grid[16][8]; 7 int total_x = 0, total_y = 0; 8 int i, j; Determine the cache performance for the following code: 1 for (i = 0; i < 16; i++) { 2 for (j = 0; j < 8; j++) { 3 total_x += grid[i][j].x; 4 } 5 } 7 for (i = 0; i < 16; i++) { 8 for (j = 0; j < 8; j++) { 9 total_y += grid[i][j].y; 10 } 11 } a) What is the total number of reads? b) What is the total number of reads that miss in the cache? c) What is the miss rate? d) How to modify the program to decrease the miss rate. Show the new miss rate you get. Assume: sizeof(int)
