Download Solution PDFThe correct answer is Option 2: Exploit the spatial locality of reference in a program.
Key Points
- Cache memory is a small, high-speed storage area located close to the CPU that stores copies of frequently accessed memory data.
- Spatial locality of reference refers to the tendency of a program to access data locations that are near each other within a short period of time.
- By placing more than one word in one cache block, the system can exploit spatial locality by fetching and storing multiple words that are likely to be used together.
- This technique reduces the number of cache misses because the required data is more likely to be found within the same cache block.
- As a result, it improves the overall performance of the system by minimizing the time spent on memory accesses.
Additional Information
- Temporal locality of reference refers to the tendency of a program to access the same data locations repeatedly within a short period of time.
- Reducing the miss penalty refers to minimizing the time taken to retrieve data from main memory when a cache miss occurs.
- Cache blocks are also known as cache lines, and they typically contain multiple contiguous memory locations.
- Modern computer systems use various cache optimization techniques to improve performance, such as multi-level caches and prefetching strategies.
