Given the following instruction frequency and CPIs for a given program running on a current generation computer: Instruction Type Instruction Frequency CPI
Simple ALU (ADD, SUB, ORR, AND, etc.) 0.3 2
Complex ALU (MUL, DIV, FP) 0.1 3
Memory operations (LDUR, STUR, etc.) 0.4 4
Control Flow (CBZ, CBNZ, B, BL, BR, etc.) 0.2 9

This machine has a frequency of 5GHz Imagine that as a computer designer, you can either (a) improve the memory performance by 1 cycle or (b) improve the branch performance (i. e., control flow instructions) by 1 cycle. How much speed up will we have for option (a) with respect to option (b)?
