Challenge Problems
Push your limits with advanced challenges
A CPU has a memory address of 11100011. The cache has 4 lines, and each block contains 2 bytes. Determine how the address maps to cache.
💡 Hint: Break down the bits and apply modulo arithmetic based on the line size.
Design a small direct mapped cache for a hypothetical system: if the main memory has 32 blocks and each block is 8 bytes, how many bits are needed for the cache lines and tags if the cache can hold 8 lines?
💡 Hint: Refer back to the organization of cache layout discussed previously.
