Question

suppose that store 1 instruction has computed the virtual memory address to be stored to as 0101100111000100. what cache set will be accessed and what tag value will be placed into the cache?

Answer 1

Without specific cache configuration details, it's impossible to provide a definitive answer.

Step-by-step explanation:

To determine which cache set will be accessed and the tag value that will be placed into the cache, we first need to understand the cache organization and the virtual memory address structure. Assuming a typical cache organization where the least significant bits (LSBs) are reserved for the block offset, following by a set of bits for the cache set index, and the remaining bits as the tag, we need more information such as the cache size, number of sets, and block size to give an accurate answer.

However, if we are to hypothesize based on the provided 16-bit address, 0101100111000100, we could consider an example where the last 4 bits are the block offset, the next 6 bits are for the set index, and the remaining 6 bits are the tag. In such a case, the set index bits (011100) would translate to a cache set number 28 in decimal, and the tag (010110) would be the tag value that will be placed into the cache.

This is merely a hypothetical example; the actual set index and tag depend on the specific cache configuration of the computer system.
