Expert Solution & Answer
Chapter 9, Problem 16RETC
Explanation of Solution
Cache consistency protocol:
If any changes are made in local cache then the same changes should be updated at all the places where the copy of the similar data is present in the memory. But this makes the data inconsistent and unreliable. To resolve this issue, cache coherence must be achieved by updating the similar data at all places and this is done by a specially designed hardware known as Snoopy Cache Controller. It keeps a track of all the changes taking place in cache data and makes the necessary updation, which is done by implementing Cache consistency protocol.
This is done in two processes:
- Write through:
- In this method the memory content is updated as soon as the cache contents are modified simultaneously...

- Write a C program using embedded assembler in which you use your own function to multiply by two without using the product. Tip: Just remember that multiplying by two in binary means shifting the number one place to the left.
