CS301: Computer Architecture

Watch this lecture. Previously, you have focused on processor design to increase performance. Now, you will turn to memory. This video introduces various methods of improving processor performance through the use of memory hierarchy. The lecture discusses memory technologies, which vary in cost and speed. We have to assume that memory is flat, but with current technology, flat memory does not meet performance demands placed on it. You will take a look at hierarchical memory and the use of cache. This video will also discuss analysis of memory hierarchies and cache performance with respect to miss rates and block size. Finally, the lecturer considers cache policy.
