3: (35 Points) In a computer system, the sizes of the address bus and data bus are 20 bits and 8 bits, respectively. The system includes a cache memory that can hold 1 KB data. Suppose you are running a program with the following data access pattern. Numbers show the addresses (as hexadecimal numbers) of data being accessed consecutively. The pattern is executed only once. At the beginning, the cache memory is empty. $00014, $00016, $00019, $00410, $00017 a) Data transfers between main and cache memories are performed using blocks of 8 bytes. The cache control unit uses the direct mapping technique. i) In what fields is the physical address divided by the cache control unit? Give the lengths of the fields. Answer: (5 p) 3: (35 Points) In a computer system, the sizes of the address bus and data bus are 20 bits and 8 bits, respectively. The system includes a cache memory that can hold 1 KB data.
