Memory Hierarchy - TAE - Tutorial And Example

WebMemory hierarchy affects performance in computer architectural design, algorithm predictions, and lower level programming constructs involving locality of reference. Designing for high performance requires considering the restrictions of the memory hierarchy, i.e. the size and capabilities of each component. AMAT uses hit time, miss penalty, and miss rate to measure memory performance. It accounts for the fact that hits and misses affect memory system performance differently. In addition, AMAT can be extended recursively to multiple layers of the memory hierarchy. It focuses on how locality and cache … Meer weergeven In computer science, Average Memory Access Time (AMAT) is a common metric to analyze computer memory system performance.
