Assume a cache has 1024 blocks, and each block can hold 32 bytes.

Determine the total number of bits (in kilobits) needed to store the cache considering the Valid bits, tags, and data for the blocks if the cache is direct-mapped. unanswered

Determine the cache block index in decimal number that contains data for the 32-bit address represented by the hexadecimal number 02AF013C. unanswered

AF0F3012 AF0F300F AF0F4011 AF0F401A AF0F3012 

If the above hexadecimal numbers represent 32-bit byte addresses the CPU reads/writes consecutively from/to the memory, then calculate the total number of cache misses for the memory accesses. unanswered

Suppose that the hardware designer decided to increase the size of each cache block to 64 bytes and decrease the number of blocks by half. What will be the percentage increase/decrease of cache size with this change, (round your answer to have only one digit after the decimal point)?
