Memory Consistency Models

This lecture covers memory consistency models, cache coherence protocols, and the impact of transistor scaling on processor frequencies. It discusses the behavior of multiprocessor systems, cache performance, and the design challenges in maintaining memory coherence. The instructor explains the differences between sequential consistency and weak consistency models, illustrating the changes in load/store queues and store buffers during program execution. The lecture also delves into the factors influencing processor performance, such as cache hits and misses, memory latencies, and memory ordering specifications.
