consider someone is using direct-mapped cache memory, each external memory address maps to what? a specific cache memory location one of many different cache memory locations a unique cache memory location, not shared with other external addresses a randomly-selected cache memory location

Explain the concept of "cache coherence" in multi-core processors and its importance for maintaining data consistency.

What is an example for a cache hit? The cache hit refers to the data that is most popular, i.e. requested most often by the CPU. The cache is "hit" with too much data and overflows. The CPU obtains the data it has requested directly from main memory (DRAM) The CPU obtains the data it has requested from a small amount of static RAM that sits between the main memory and the CPU.

What should the CPU do when a cache request arrives while a block is being flushed back to main memory from the write buffer?

The write buffer will return a block to main memory while the CPU submits a cache-unmet request. What may happen next?

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?

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?

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?

In relation to storage (main memory) management the following are true: Group of answer choices The bound register converts logical addresses to physical addresses Paging eliminates fragmentation completely Some portions of large programs are never executed Paging is more efficient that variable-partition multiprogramming The first fit algorithm is more efficient than the best fit algorithm

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?

What should the CPU do if it receives a cache request while it is flushing a block from the write buffer back into main memory?

What action should the processor take if it receives a cache request while it is in the process of flushing a block back into main memory from the write buffer?
