a) Suppose we have a 64 KB, direct-mapped cache with 8-word blocks. Determine how many bits are required for the tag, index, and offset fields for a 32-bit memory address. b) If instead, we use a 64 KB, 4-way set-associative cache with 8-word blocks, how many bits will be required for the tag, index, and offset fields for a 32-bit address? c) What type of cache is shown in problem 2? How many bits are required for this cache’s tag,...

6.20 Assume that the ASC memory is organized as 8 bit per word. That means each single-address instruction now occupies two words and zero-address instructions occupy one word each. The ASC bus structure remains the same. MBR is now 8 bits long and is connected to the least significant 8 bit of the bus structure. Rewrite the fetch microprogram

Q2. (4 pts) A certain microprocessor (uP) has a 37-bit address bus and a 32-bit wide data bus. Here, similar to Q1, we are using byte packing, that is, we should be able to access each byte in the memory. Assume that you are using a memory chips organized as 128K by 8 bits. Q2-1.Divide the 37-bit address lines into page number bits, offset bits and byte address bits. Q2-2.How many 128K by 8 memory devices would you need to...
