A particular computer has a single level cache with a miss rate of 6.85%. You are required to design a second level cache that brings the global miss rate of the whole cache system to 3.98%. what would be the miss rate percent required for the second level cache?

`Hey,
Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries
We will access L2 cache only when we have miss in L1 cache
therefore
global miss rate = L2 misses * L1 miss rate
L2 misses = 0.0398 / 0.0685 =0.5810
so l2 miss rate = 58.10%
Kindly revert for any queries
Thanks.

Consider adding a fast second-level cache to a computer with only a single level cache. Suppose data can be accessed from the second level cache 12 times faster than it can be accessed from memory, and also suppose that the second level cache is used 30% of the time and the first level cache is used 70% of the time. What is the speedup of the system after adding the second-level cache, compared to the original system?

2. Cache hierarchy You are building a computer system with in-order execution that runs at 1 GHz and has a CPI of 1, with no memory accesses. The memory system is a split L1 cache. Both the I-cache and the D-cache are direct mapped and hold 32 KB each, with a block size of 64 bytes. The memory system is split L1 cache.

A computer system has the following memory timing clock cycle (CC) specification: Cache access time 1 CC, Main memory access time 100 CC, and Virtual memory access time 100,000 CC. Find the ratio of Average Memory Access Times (AMAT) of the following two programs and determine which program executes faster: B5. cache miss rate : 25% Main memory miss rate Program B: Cache miss rate 20% Main memory miss rates 10% 5%

a) Calculate the AMAT for a cache system with one level of cache between the CPU and Main Memory. Assume that the cache has a hit time of 1 cycle and a miss rate of 11%. Assume that the main memory requires 300 cycles to access (this is the hit time) and that all instructions and data can be found in the main memory (there are no misses). b) Let us modify the cache system from part (a) and add...

Assume a cache with a write-through policy, non-write allocate. Your cache has a miss rate of 5%. There is a 150 cycle miss penalty. Additionally, it takes an extra 30 cycles to do a write. Your program has a base CPI of 1, is 20% loads, and 5% stores. What will its CPI be?

Consider a 64-bit computer with a simplified memory hierarchy. This hierarchy contains a single cache and an unbounded backing memory. The cache has the following characteristics: • Direct-Mapped, Write-through, Write allocate. • Cache blocks are 4 words each. • The cache has 256 sets. (a) Calculate the cache’s size in bytes. (b) Consider the following code fragment in the C programming language to be run on the described computer. Assume that: program instructions are not stored in cache, arrays are...

Exercise 8.16 You are building a computer with a hierarchical memory systenm that consists of separate instruction and data caches followed by main memory. You are using the ARM multicycle processor from Figure 7.30 running at 1 GHz (a) Suppose the instruction cache is perfect (i.e., always hits) but the data cache has a 5% miss rate. On a cache miss, the processor stalls for 60 ns to access main memory, then resumes normal operation. Taking cache misses into account,...

Suppose you have a machine with separate I- and D- caches. The miss rate on the I-cache is 2.6% , and on the D-cache 3.8%. On an I-cache hit, the value can be read in the same cycle the data is requesfed. On a D-cache hit, one additional cycle is required to read the value. The miss penalty is 100 cycles for data cache, 150 for I-cache. 40% of the instructions on this RISC machine are LW or SW instructions,...

Operating Systems Questions (Please help if you can) 1. A computer has cache, main memory, and a disk used for virtual memory. If a referenced word is in the cache, 20ns are required to access it. If it is in main memory but not in the cache, 60ns are required to load it into the cache (this includes the time to originally check the cache), and then, the reference is started again. If the word is not in main memory,...
