FAQs on Problems on Set Associative Mapping - 2 Video Lecture - Question Bank for GATE Computer Science Engineering - Computer Science Engineering (CSE)

1. What is set associative mapping in computer science engineering?
Ans. Set associative mapping is a cache mapping technique used in computer science engineering. It divides the cache into multiple sets and allows each set to contain a certain number of cache lines. Each memory block is mapped to a specific set based on its address, and within that set, it can be placed in any available cache line. This mapping technique aims to balance the trade-off between direct mapping and fully associative mapping.
2. How does set associative mapping differ from direct mapping?
Ans. Set associative mapping differs from direct mapping in the number of cache sets. In direct mapping, each memory block is mapped to a specific cache line in a one-to-one manner. However, in set associative mapping, the cache is divided into multiple sets, allowing each memory block to have multiple possible cache line locations within a set. This flexibility enables better cache utilization and reduces the chances of cache conflicts.
3. What is the advantage of using set associative mapping?
Ans. Set associative mapping offers several advantages in computer science engineering. Firstly, it provides a compromise between the simplicity of direct mapping and the flexibility of fully associative mapping. This allows for better cache utilization and reduces the chances of cache conflicts. Additionally, set associative mapping can improve cache hit rates, leading to faster access times and improved overall system performance.
4. How does set associative mapping handle cache conflicts?
Ans. Set associative mapping handles cache conflicts by allowing memory blocks to be placed in any available cache line within a set. When a cache conflict occurs, meaning multiple memory blocks map to the same set, the cache controller selects an appropriate cache line based on a replacement policy. Common replacement policies include Least Recently Used (LRU) and Random. By allowing flexibility in cache line selection, set associative mapping mitigates the impact of cache conflicts.
5. How can the number of sets affect set associative mapping?
Ans. The number of sets in set associative mapping has a significant impact on cache performance. Increasing the number of sets can improve cache utilization and reduce the chances of cache conflicts. However, a higher number of sets also increases the complexity and cost of cache implementation. It is essential to strike a balance between the number of sets and overall system requirements to achieve optimal cache performance.
