Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

A cache memory needs an access time of 30 ns and main memory 150 ns, what is the average access time of CPU (assume hit ratio= = 80%)?
Cache memory systems are designed such that the computer first checks the L1 cache for the desired memory. If the data is there, it accesses it and is done. It only checks the L2 cache if the data is not found in the L1 cache. Likewise, the computer checks the L3 cache if the desired data is not found in the L2 cache, and finally it on only checks main memory if the data is not found in the L3 cache. Imagine a computer system with the following cache access times: L1 cache: 3 processor cycles L2 cache: 10 processor cycles L3 cache: 25 processor cycles Main memory: 100 processor cycles So, in the best case, the desired data would be immediately found in the L1 cache, which requires only 3 cycles to check. Conversely, in the worst case, the desired data would only be in main memory, which would require 138 cycles to access (3 cycles to check L1 cache + 10 cycles to check L2 + 25 cycles to check L3 + 100 cycles to access main memory). What is important, however, is the average…
