Homework Answers
`Hey,
Note: In case of any queries, just comment in box I would be very happy to assist all your queries
One way of calculating the read efficiency of the data cache is by using average reading time in a particular interval
Average reading time = Amount of time in case of cache hit + Rate at which cache miss happens * penality for this miss.
Rate will be a value between 0 to 1. Notice that here we are taking both best and the worst case scenario into consideration. This can be further extended for calculating this seperately for instruction access and data acesss. For this we need to know what percent of references are data references and what percent of references are instruction references.
Kindly revert for any queries
Thanks.

Assume the access time for an L2 cache with a 64 byte cache block is 20 cycles for the 1st 64 bit (8 byte) word, and an additional 2 cycles for each subsequent word. What is access time (time before L1 can pass incoming data on to processor) for a read of a word at 5ed705 if the full block must be read before using data? With critical word first? With early restart?

Assume the cache can hold 64 kB. Data are transferred between main memory and the cache in blocks of 4 bytes each. This means that the cache is organized as 16K=2^14 lines of 4 bytes each. The main memory consists of 16 MB, with each byte directly addressable by a 24-bit address (2^24 =16M). Thus, for mapping purposes, we can consider main memory to consist of 4M blocks of 4 bytes each. Please show illustrations too for all work. Part...
