If the requested data is too large to fit in the cache, a write buffer will transmit it back to the CPU from main memory. What is the next step?
Suppose a computer using fully associative cache has 216 bytes of byte-addressable main memory and a cache of 64 blocks, where each cache block contains 32 bytes.Q.) How many blocks of main memory are there?
Assume a RAM consists of 1M bytes, and it is byte addressable. It uses a cache memory consisting of 16 4K-byte blocks. How many bits are in a RAM address? How many bytes are in the cache memory? How many bits are in the cache tag? How many bits are needed to determine a byte's position within a block?
What should the CPU do when a cache request arrives while a block is being flushed back to main memory from the write buffer?
You have a CPU which contains two processor cores, connected via a bus. Each core has its own 8 row, direct-mapped L1 cache and the two caches are coherent via snoopy cache coherent over the bus, with a write-invalidate mechanism. The block size in the cache is 8 bytes (two words). Core A: Load byte address 63 Core A: Load byte address 57 Core B: Store byte address 63 Core A: Store byte address 63 Core B: Load byte address 102 Core A: Load byte address 121 Core A: Load byte address 57 For each access from the list above, please indicate whether the access would be a hit, a compulsory miss, a conflict miss, a capacity miss, or a coherence miss. Before the sequence begins, both caches are empty. First access (Core A address 63): Second access (Core A address 57): Third access (Core B address 63): Fourth access (Core A address 63): Fifth access (Core B address 102): Sixth access (Core A address 121): Seventh access (Core A address 57):
What should the processor do if a cache request cannot be satisfied while a block is being written from the write buffer back into main memory?
When a processor submits a request that cannot be satisfied by the cache, and a block is being pushed back to main memory from the write buffer, should something happen?
If the data being requested is too large to fit in the cache, a write buffer will bring it to the attention of the CPU by retrieving it from main memory. What should the next step be?

Describe the advantages of memory address translation with segmentation technique.
What action should the CPU take if it is unable to satisfy a cache request when writing a block from the write buffer back into main memory?
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:
