Lecture
This lecture discusses the importance of cache memory, focusing on spatial and temporal locality. It explains how cache helps by re-accessing the same address in a short time period (temporal locality) and accessing addresses in the same block (spatial locality). The concept is illustrated with examples and analogies, emphasizing the impact of cache size and block size on cache efficiency. Different cache architectures are explored, highlighting the trade-offs between spatial and temporal locality. The lecture concludes by discussing the optimal cache configuration based on program characteristics.
