Given a memory system with 64 bytes of cache, where each block is 16 bytes, determine the number of blocks in the cache. Then, if you access a byte at address 20, what cache line will it map to?
💡 Hint: Start by calculating the number of blocks, then determine the mapping.
Design a cache system with 8 lines, each with a tag size of 3 bits. If your total addressable memory is 32 bytes, how many bits will be reserved for cache indices and offsets?
💡 Hint: Break it into parts: identify how many bits go where and sum them correctly.
