Consider the implications of data access speed.
Consider a direct-mapped cache with 32 lines and a block size of 8 bytes. Calculate the cache line for a byte address of 5280.
Use division for block number, followed by modulus for the cache line.
If a direct-mapped cache has 64 lines and a word size of 4 bytes, how many blocks can the cache store if the total cache size is 16 KB?
Explore the relationship between total size, block size, and cache lines.
