For the cache design of the preceding problem, suppose that increasing the line size from one word to four words results in a decrease of the read miss rate from 3.2% to 1.1%. For both the nonburst transfer and the burst transfer case, what is the average miss penalty, averaged over all reads, for the two different line sizes?

Match each type of miss with its definition. Compulsory Miss Capacity Miss Conflict Miss ✓ [Choose ] A miss that occurs because this is the first time we have accessed the block that contains the desired value A miss that occurs because the values that we are working on both map to the same place in the cache and therefore can't both A miss that occurs because we are unable to fit all of the values that we are working on inside the cache [Choose ]

CA_6 We study the properties of cache memory, and for reasons of easier design and efficient circuits, we assume that the cache capacity is 2i Bytes, and cache line size is 2j Bytes, with i and j being natural numbers:  (a)  How many bits should the tag field have? And can the tag field contain 0 bit (i.e., be empty)? Elaborate  (b)  Repeat the above for the index field. (c)  Repeat the above for the byte-offset field. (d) Finally, depict a figure showing a cache line, indicate what fields it possibly has, state the possible sizes of these fields, and explain the uses of these fields.

Solve the cache problem for Direct Map. Cache holds 64 words, and a block size is 16 words. (5 pts for correct tag/index, 5 pts for correct cache set up # of blocks, 10pts for filling in cache correctly)   Show each access being filled in with a note of hit or miss. You are given byte address and the access are: 0x3ff, 0x000, 0x200, 0x3f0, 0x009, 0x320, 0x32f.

Take into account the following scenario: we have a byte-addressable computer with 2-way set associative mapping, 16-bit main memory addresses, and 32 blocks of cache memory. Since there are 8 bytes in a block, you can use that information to calculate how big the offset field has to be.

Computer Science You are given a cache that has 16 byte blocks, 512 sets, and is 2-way set associative. Integers are 4 bytes. Give the C code for a loop that has a 100% miss rate in this cache but whose hit rate rises to almost 100% if you double the size of the cache. Do not assume the starting indexes of any arraysarrays.

Suppose we have a byte-addressable computer with a cache that holds 16 blocks of 4 bytes address has 8 bits, to which cache set would the hexadecimal address OxBE map if the computer mapping? each. Assuming that each memory uses 2-way set associative

12. Consider a virtual memory system running on a RISCCPU. Page tables are not locked in memory and may be swapped to disk. An lw (load word) instruction reads one data word from memory; the address is the sum of the value in a register and an immediate constant stored in the instruction itself. Neither machine instructions nor page-table entries nor data words can cross a page boundary. In the worst case, how many page faults could be generated as a result of the fetch, decode, and execution of an lw instruction?

Let's pretend for a moment that we have a byte-addressable computer with fully associative mapping, 16-bit main memory addresses, and 32 blocks of cache memory. The following holds true if each block is 16 bits in size: a) Determine how many bytes the offset field is. Measure the tag field's width and height in pixels (b).
