Assume a computer system has a main memory of 256 Bytes. The following is a memory byte-access trace history of a program run on this system. For example, as it is shown, the program first accesses memory address 0000 0000, and  then it accesses memory address 0000 0001 and so on. Note the memory addresses are represented in binary: 00000000, 00000001, 00000010, 00000011, 00001000, 00010000, 00010001, 00000100, 00000101, 00000110,  00000111, 00001001, 00001010, 00001011, 00001100, 00001000, 00001001, 00001010, 00011100, 00011101. If the Cache of this computer system is re-organized to a 16-Byte direct mapped cache with a block size of 4 Bytes, what would be the hit rate after the 20th memory access is finished?

Question

Assume a computer system has a main memory of 256 Bytes. The following is a memory byte-access trace history of a program run on this system. For example, as it is shown, the program first accesses memory address 0000 0000, and  then it accesses memory address 0000 0001 and so on. Note the memory addresses are represented in binary:
00000000, 00000001, 00000010, 00000011, 00001000, 00010000, 00010001, 00000100, 00000101, 00000110, 
00000111, 00001001, 00001010, 00001011, 00001100, 00001000, 00001001, 00001010, 00011100, 00011101.

If the Cache of this computer system is re-organized to a 16-Byte direct mapped cache with a block size of 4
Bytes, what would be the hit rate after the 20th memory access is finished?
