In a pipelined processor, a program has 5% instructions belonging to load and store instructions. This program spends 20% of its execution time for load instructions and 10% of its execution time for store instructions. Since the data cache miss rate is high shown in this program, the processor architect proposes a new data cache architecture that improves the 4x execution time of load instructions (4x faster) and 2x execution time of store instructions (2x faster). Then, this new processor will achieve 1.25x speedup. Which statements are correct when using the processor with this new cache architecture?
