A CPU has 32-bit memory address and a 256 KB cache memory. The cache is organized as a 4-way set associative cache with cache block size of 16 bytes. What will be the number of bits in the TAG, SET, BYTE offset fields?

For a direct-mapped cache design with a 32-bit address, the following bits of the address are used to access the cache. We assume that each word has 4 bytes. How many entries does the cache have?

In the event of an unsatisfied cache request, what should happen to the block being sent to the main memory from the write buffer?

How should the processor handle a cache request when writing a block from the write buffer to main memory?

If the CPU receives a cache request while returning a block from the write buffer to main memory, what action should it take?

At the same time as the processor is making a request to the cache, it is returning a block from the write buffer to main memory.

Suppose a byte-addressable computer using set-associative cache has 216 bytes of main memory and a cache of 32 blocks, and each cache block contains 8 bytes.Q.) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache?

At the same time as it sends a block from the write buffer back to main memory, the processor makes a request to the cache.

When a block is being sent back to main memory from the write buffer, what should happen if the processor sends a cache-unfulfilled request?

When a block is being sent back to main memory from the write buffer, what should happen if the processor sends a cache-unfulfilled request?

It is important to differentiate between a cache that is completely associative and one that is directly mapped.

When a block is being sent back to main memory from the write buffer, what should happen if the processor sends a cache-unfulfilled request?
