A spatial Cache Locality visualizer simulation demonstrating how the CPU fetches a 32-byte cache line of 64-bit float values(i.e. 8-byte each) at once inside the L1 D-cache.
So that if it has to access sequential data next, it doesn't have to fetch it from DRAM, saving around 200+ cycles to reduce the memory wall, consequently increasing performance through cache hits.
