QUESTION 2 Suppose a computer using direct mapped cache is using 216 (64K) bytes of byte-addressable main memory, and a cache size of 4096 bytes, where each cache block contains 256 bytes. a) How many blocks of main memory are there? b) What is the format of a memory address as seen by cache, i.e. what are the length of the tag, block, and offset fields? c) Given memory address 2B9D (in hexadecimal format), which block in the cache will be searched? (What is that block's id?)

I have a little bit problem with my late quiz for computer architecture, I get the answer from my lecturer but I still don't feel fully understand, can I ask for some help: In a computer system, the memory has 32 blocks and the cache has 8 blocks. Assume there is only one word per block with 4 bytes in one word. The reference sequence in terms of word location is 0, 2, 4, 10, 5, 12, 8, 18, 13. If the cache is direct-mapped, how many misses do we have if the cache is initially empty? Can you give the hit or miss for each reference?

Computer science homework Please help me with this homework question.

Suppose a byte-addressable computer using set associative cache has 2^24 bytes of main memory and a cache size of 64K bytes, and each cache block contains 32 bytes. a) 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? b) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache?

4. Assume 32 bit memory addresses, which are byte addresses. You have a direct-mapped cache with a block size of 8 bytes, and a size of 128 blocks. How many bits will the index, block offset, and tag be? How many total bits are required for the cache, including the data?

Question 4

4. Suppose a computer using a fully associative cache has 2^24 byte of byte-addressable main memory and a cache of 128 blocks, where each block contains 64 bytes. a) How big in kilobytes is main memory? b) How big in bytes is cache? In kilobytes? c) How many blocks of main memory are there? d) What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag and offset fields? e) To which cache block will the memory address 0x01D8729A map?

Suppose a computer using fully associative cache has 224 bytes of byte-addressable main memory and a cache of 128 blocks, where each block contains 64 bytes.Q.) To which cache block will the memory address 0x01D872 map?

5. The ending address of a memory of size 1KB is 33FFH, then what is the starting address of the memory.
