`Hey,
Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries
Tavg = h*c+(1-h)M
where h =cache hit rate
(1-h) = miss rate
c = time to access information from cache
M = miss penalty (time to access main memory)
Overall Average memory access time =cache hit ratio * average cache access time + (1 – cache hit ratio) * miss penalty(or memory access time) =
(60/100)*6+(1-0.60)*32
=16.4 nsec
Kindly revert for any queries
Thanks.

(a) A computer system with a cache memory has an average memory access time of TM= 50 ns with a hit ratio of h= 80%. The primary memory access time is TP=120 ns. What is the cache memory access time, TC?
6. Memory Access Time [15 points] Consider a MIPS processor that includes a cache, a main memory, and a hard drive. Access times of cache memory, main memory, and hard drive are 5 ns, 200 ns, and 1000 ns, respectively. Assume that cache memory is divided into instruction cache and data cache. Assume that data cache has a 90% hit rate. Assume that main memory has a 98% hit rate and hard drive is perfect (it has a 100% hit...
Question 4 - [25 Points] Part (a) - Average Access Time (AMAT) The average memory access time for a microprocessor with One (1) level (L1) of cache is 2.4 clock cycles - If data is present and valid in the cache, it can be found in 1 clock cycle If data is not found in the cache, 80 clock cycles are needed to get it from off- chip memory Designers are trying to improve the average memory access time to...
Question 27 Suppose the cache access time is 10ns, main memory access time is 200ns, and the cache hit rate is 90%. Assuming parallel (overlapped) access, what is the average access time for the processor to access an item?
Question 27 7 pts Suppose the cache access time is 10ns, main memory access time is 200ns, and the cache hit rate is 90%. Assuming parallel (overlapped) access, what is the average access time for the processor to access an item? 29ns
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...
1. A system has the average cache access time in 50 nanoseconds and the average main memory access time in 500 nanoseconds. Assuming the total number of requests is 2500 and 1000 of those requests are found in the cache. a. (1 point) What's the hit ratio? b. (1 point) What's the average memory access time?
(a)What is the average memory access time (AMAT) if a cache uses write-back strategy and 20% of the data blocks to be swapped out are dirty. Assume that the miss rate is 15%, the hit time of the cache is 1 cycle and the miss penalty is 8 cycles for the data blocks that are not dirty and 20 cycles for those blocks that are dirty. (b) What is the speedup up if we add a “write-buffer” that eliminates 40%...
4B, 20%) compare performance of a Processor with cache vs. without cache. Assume an Ideal processor with 1 cycle memory access, CPI1 Assume main memory access time of 8 cycles Assume 40% instructions require memory data access Assume cache access time of I cycle Assume hit rate 0.90 for instructiens, 0.80 for data Assume miss penalty (time to read memory inte cache and from cache to Processor with cache processor) is 10 cycles >Compare execution times of 100-thousand instructions: 4B,...
Consider 512Kx8bits dynamic RAM chips where the memory access time is 2/3 of the memory cycle time. These chips have an Address Bus, a bi-directional Data Bus, a Read/Write control line and a Chip Select line. (a) Draw the diagram of a memory organization that will contain 4 megabytes, will have a 32-bit bi-directional data bus and will yield one word (32-bits) every access time if words are read from consecutive memory locations (in bursts). Clearly show and explain the...
