Question 3 The access time of a cache is 80 ns and the access time of main memory is 1200 ns. We have 85% of instructions are directed to read while 15% is for writes. Hit ratio is 92%. A write through procedure is used. A. Give the average access time considering only the read requests B. Give average access time for both read and write requests. C. Give the overall hit ratio given the write cycle as well. Question...

Suppose a computer using fully-associative cache has 222 words of main memory and a cache of 32 blocks, where each cache block contains 16 bytes. How many blocks of main memory are there? Assuming memory addressing starts from zero, what is the highest memory address? How many bits are needed to represent all of the memory addresses? What is the format of a memory address as seen by the cache, that is, what are the sizes of the tag and...

A 2-way set associative cache consists of four sets 0, 1, 2, 3. The main memory is word addressable (i.e. treat the memory as an array of words indexed by the address). It contains 2048 blocks 0 through 2047, and each block has eight words. (a) How many bits are needed to address the main memory? (b) Show how a main memory address will be translated into a tag, a set number, and an offset within a block. Illustrate this...

Question 20 5 pts Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. How many bits can be used for the memory address? Question 21 5 pts Suppose we have...
