Caches are important in providing processors with a high-performance memory hierarchy. Below is a list of 32-bit memory address references represented in Hex. 0x00C, 0x2D0, 0x0AC, 0x008, 0x2FC, 0x160, 0x2F8, 0x038, 0x2D4, 0x0B0, 0x2E8, 0x3F4 You are asked to optimize a cache design for the given references. There are three direct- mapped cache designs possible, all with 8 words of data: C1 has 1-word blocks, C2 has 2-word blocks, and C3 has 4-word blocks. In terms of miss rate, which cache design is the best?
