Media applications that play audio or video files are part of a class of workloads called "streaming" workloads i.e., they bring in large amounts of data but do not reuse much of it. Consider a video streaming workload that accesses a 512 KiB working set sequentially with the following address stream: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9... (a) Assume a 64 KiB direct-mapped cache with a 32-byte block. What is the miss rate for the address stream above? How is this mis rate sensitive to the size of the cache or the working set? How would you categorize the misses this workload is experiencing, based on the 3C model?
