9. Main memory is byte addressed using 32 bit addresses. The index and offset fields for a direct-mapped, write-back cache design are 11 bits and 5 bits, respectively. How many bytes of the 32-bit address space can be mapped into this cache? How many bytes of overhead storage are needed to manage cache access for this cache design? What percentage of all the locations in the cache that store a bit are used to hold memory hierarchy content? a. b. c. 9. Main memory is byte addressed using 32 bit addresses.
