“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 buff er that prefetches sequentially adjacent cache blocks into a separate buff er when a particular cache block is brought in. If the data is found in the prefetch buff er, it is considered as a hit and moved into the cache and the next cache block is prefetched. Assume a two-entry stream buff er and assume that the cache latency is such that a cache block can be loaded before the computation on the previous cache block is completed. What is the miss rate for the address stream above?Cache block size (B) can aff ect both miss rate and miss latency. Assuming a 1-CPI machine with an average of 1.35 references (both instruction and data) per instruction, help find the optimal block size given the following miss rates for various block sizes. 8: 4% 16: 3% 32: 2% 64: 1.5% 128: 1%…

A memory system has 4 KB byte-addressable main memory and a direct-mapped cache that consists of 8 blocks with 16 bytes per block. The following shows the main memory address format that allows us to map addresses from main memory to cache. Note: 12 bit address, 4 bit offset, 3 bit $block, and 5 bit tag Assume the cache directory shown below:
Suppose a byte-addressable computer using set-associative cache has 216 bytes of main memory and a cache of 32 blocks, and each cache block contains 8 bytes.Q.) If this cache is 2-way set associative, what is the format of a memory address as seen by the cache; that is, what are the sizes of the tag, set, and offset fields?
What differentiates an associative cache from a directly mapped cache is the ability to arbitrarily associate data objects.
How does a cache function when it stores data in a wholly associative format?
A message slot is a cache line that contains status flags and the message itself. The state can be empty or ready, and communication occurs through a single cache line. Both the sender and the receiver write the message to the cache line. The receiver updates the state from empty to ready, then polls the cache line in a loop waiting for the sender to send a message. The sender waits in a tight loop until the receiver acknowledges the cache line, changes the state from ready to empty, and acknowledges receipt. Explain that the system uses a snooping cache coherence protocol and describe the cache-coherence transaction taking place on the coherence bus when a message transfer occurs.
