A microprocessor has an on-chip 2-way set associative cache with a total capacity of 8 kByte. Each line in cache can store sixteen 8-bit words. It has a total addressable space of 16 MBytes. Number of bits for set (d) equal: a. 2 O b.4 O c. 8 O d. 12 If the RAM has a two byte data word and address bits are grouped for direct mapping with a cache memory as follow: 14 bits 9 bits 5 bits What is the number of lines in the related cache? O a. 256 O b.6K O c. 512 O d. 32 If the RAM has a two byte data word and address bits are grouped for direct mapping with a cache memory as follow: 14 bits 9 bits 5 bits How many blocks does the RAM contain? O a. 16 K O b. 64 O c. 32 K O d. 32
