$5\mathrm{.}8$ 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 word address stream:

$0,1,2,3,4,5,6,7,8,9$dots

$5\mathrm{.}8\mathrm{.}1[10]$$$$5\mathrm{.}4,5\mathrm{.}8>$ 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 miss 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 $3$C model?

$5\mathrm{.}8\mathrm{.}2[5]$$$$5\mathrm{.}1,5\mathrm{.}8>$ Re$-$compute the miss rate when the cache block size is $16$ bytes, $64$ bytes, and $128$ bytes. What kind of locality is this workload exploiting?

$5\mathrm{.}8\mathrm{.}3[10]$ $$5\mathrm{.}13>$ "Prefetching" is a technique that leverages predictable address patterns to speculatively bring in additional cache blocks when a particular cache block is accessed. One example of prefetching is a stream buffer that prefetches sequentially adjacent cache blocks into a separate buffer when a particular cache block is brought in$.$ If the data are found in the prefetch buffer, it is considered
