- When the amount of data requested is more than what can be stored in cache, the CPU fetches it from main memory and returns it through the write buffer. Now what?arrow_forwardWhen a processor makes a request that cannot be satisfied by the cache while moving a block back to main memory from the write buffer, what happens?arrow_forwardWhat happens if the processor sends a request to the cache that is refused while the write buffer is writing a block back to main memory?arrow_forward
- What should happen if the processor sends a request that hits the cache while sending a block from the write buffer back to the main memory?arrow_forwardIn this scenario, the CPU is simultaneously making a cache request and returning a block from the write buffer to main memory.arrow_forwardWhat should occur if the processor sends a request to the cache while a write buffer block is being returned to main memory?arrow_forward
