a byte-addressable main memory of size 256mb with blocks of 32 bytes in size. the cache memory can hold up to 64 blocks

Answers

Answer 1

The main memory can hold a total of (256 * 1024 * 1024) / 32 = 8,388,608 blocks.

What are main and cache memory?

he main memory in this system has a size of 256 megabytes, which is equal to 256 * 1024 * 1024 bytes. With blocks of 32 bytes in size, this means that the main memory can hold a total of (256 * 1024 * 1024) / 32 = 8,388,608 blocks.

The cache memory, on the other hand, can hold up to 64 blocks. This means that it can store a small fraction of the data that is stored in the main memory. In order to access data that is not stored in the cache, the system must fetch it from the main memory, which takes longer than accessing data directly from the cache.
