Study Notes
Cache Memory
- Fully Associative Cache: allows a given block to reside in any cache line, requiring extensive tag checking to determine if a requested block is in the cache.
Multilevel Cache System
- Primary Benefit: improves cache performance by reducing the average memory access time.
Address Translation Optimization
- Translation Lookaside Buffers (TLBs): minimizes the time required to translate virtual addresses into physical addresses.
Cache Design Strategies
- Read Priority: gives priority to read misses over write misses to avoid stalling the processor during read operations.
- Set Associative Cache: employs a method where each block can reside in a specific set of cache lines, reducing tag check complexity compared to fully associative caches.
Cache Optimization Techniques
- Block Size Optimization: focuses on reducing the miss rate by storing larger blocks of contiguous memory in the cache to exploit spatial locality.
- ** Parallelism**: reduces miss rate by using parallelism in cache operations.
- Hit Time Reduction: avoids address translation during cache indexing to reduce hit time.
Multilevel Caching
- Contribution to Cache Performance: improves cache performance by reducing the average memory access time.
Cache Performance Optimization
- Hit Rate: refers to the frequency of cache hits.
- Principle of Locality: mainly concerned with the idea that the data being accessed is likely to be located near the data that was accessed in the recent past.
- Instruction-Level Parallelism: can be achieved in processor design by pipelining and out-of-order execution.
Address Translation
- Main Objective: to minimize the time required to translate virtual addresses into physical addresses.
Cache Optimization Terms
- Priority Read Misses: refers to prioritizing read misses over write misses to avoid stalling the processor during read operations.
- Associativity: impacts cache performance optimization by affecting the number of blocks that can be stored in the cache.
