Suppose we have the following parameters on a two level cache system (L1 is closer to CPU). L1 Cache: Size = 4Kbytes Hit rate: 1 cycle Miss rate: 0.10 misses per memory reference Miss penalty: 3 cycles if found in L2 cache L2 Cache: Size = 64Kbytes Miss rate: 0.02 misses per memory reference Miss penalty: 10 cycles Assume that 20% of all instructions reference memory (i.e., load and store). What is the CPI of this processor (In a perfect cache system, each instruction takes 1 cycle)?

Q: In the event that the processor sends a request that is refused in the cache while the write buffer…

A: Introduction: The CPU writes straight to the main memory without a write buffer. In a system with a…

Q: What should the processor do if a cache request cannot be satisfied while a block is being written…

A: The answer for the above question is given in the below step for your reference.

Q: Assume a program has 20% store and load. When we run this program in a computer, we observe that L1…

A: given information:- store and load instruction = 20% L1 hit rate = 98%      L1 data hit rate = 96%…

Q: Suppose a computer using direct mapped cache has 4M byte of byte-addressable main memory, and a…

A: Computer memory is a device that stores data and allows us to retrieve it when needed. Primary…

Q: When the processor submits a request that cannot be satisfied in the cache while a block is being…

A: When a processor experiences a cache miss while waiting for data to be fetched from main memory,…

Q: , 25% reads and 10% writes, and every other instruction type is 1 cycle. You have a 2-way set…

A: since addresses size supported by the hardware's is 40bit's total size of the main memory is 240…

Q: What should the CPU do if a cache request comes when a block is returned from the write buffer to…

A: What is CPU: CPU stands for Central Processing Unit. It is the primary component of a computer…

Q: Look at the figure, can you explain to me from the figure the following special registers in the…

A: PC: Program counter holds the address of the instruction which is currently being executed. NPC:…

Q: A program sees a 4% miss rate on both the Instruction Cache and the Data Cache. Every instruction…

A: Answer: Our guidelines is answer the first three question from the first question so we will see…

Q: The write buffer returns a block to main memory while the processor issues a request that cannot be…

A: The above question is solved in step 2 :-

Q: I have a little bit problem with my late quiz for computer architecture, I get the answer from my…

A: Following information has been given: Main memory size = 4 Gbytes(GB) = 210x 210x 210x 22 bytes…

Q: At the same time as the processor is making a request to the cache, a block that was previously…

A: Explanation: When a Processor has to make a comment, it first checks to see whether the address to…

Q: A cache memory needs an access time of 30 ns and main memory 150 ns, what is the average access time…

A: Here hit rate = 0.80  =  H Miss rate = 0.20  = (1- H) Cache access time = 30 ns = C Memory Access…

Q: Suppose you have a processor with a base CPI 1.0, assuming all references hit in the primary cache…

A: a) What is the effective CPI?b) What will be the effective CPI if we add a new cache (L3) that has…

Q: What should happen when the processor issues a cache-unfulfilled request while a block is being sent…

A: Given: The write buffer and cache operate separately from one another. The request may be answered…
