What is the purpose of "prefetching" in CPU memory systems?
Correct! Well done.
Incorrect.
The correct answer is A) A technique where the hardware or software anticipates future memory accesses and loads data into the cache before it is actually requested, reducing wait time when it is needed
A
Correct Answer
A technique where the hardware or software anticipates future memory accesses and loads data into the cache before it is actually requested, reducing wait time when it is needed
Explanation
By predicting which memory addresses a program will access next (e.g., sequential array access), prefetchers bring data into cache ahead of time, hiding memory latency and reducing cache misses.
