A computer system uses 32-bit memory addresses. It has a 32Kbyte direct-mapped Ll cache with 64 bytes per cache block. (a) Calculate the number of bits in each of the Tag", "Index", and "Byte Select" fields of the memory address. (b) How many total SRAM bits are in this cache? Include tag, valid, dirty and data bits. (c) What if this computer system is also using a 4Mbyte 16-way set-associative L2 cache with 128 bytes per cache block. Repeat all the calculations for the L2 cache.
