Given 1 valid bit plus the tag, determine the size of the overhead memory in bytes. Show your work, how you did the calculation - better chance of partial credit. 11. (2 pts) How many possible tags can map to each row? 12. (6 pts) My program reads 4 bytes at address 0x2CAFE. Two cache blocks are accessed. What are the indices and tags for each of these two blocks? Tag Index Tag Index 13. (2 pts) Suppose my program reads one byte at address Ox7F3C4 and it is a miss, the cache block must be populated. How many bytes from main memory will need to be read?
