ALSO: What is the hit ratio for the memory accesses (Round to the nearest percent.)

Suppose we have a computer that uses a memory address word size of 8 bits. This computer has a 16-byte cache with 4 bytes per block. The computer accesses a number of memory locations throughout the course of running a program. Suppose this computer uses direct-mapped cache. The format of a memory address as seen by the cache is shown below: ``` Tag Block Offset 4 bits 2 bits 2 bits ``` Given the following cache contents: - **Block 0:** - Tag: 1110 - Cache Contents (represented by address): - 0xE0 - 0xE1 - 0xE2 - 0xE3 - **Block 1:** - Tag: 0001 - Cache Contents (represented by address): - 0x14 - 0x15 - 0x16 - 0x17 - **Block 2:** - Tag: 1011 - Cache Contents (represented by address): - 0xB8 - 0xB9 - 0xBA - 0xBB - **Block 3:** - Tag: 0110 - Cache Contents (represented by address): - 0x6C - 0x6D - 0x6E - 0x6F If each of the following addresses were accessed in sequence, identify if they would be a "hit" or a "miss": - 0x4F - 0x6E - 0xBA - 0x4E - 0x6F - 0xBB
