A program consists of 40% ALU, 20% Load, and 40% Branch instructions. Suppose that each Load instruction has a data dependency with an ALU instruction that immediately follows it in the program execution causing a cycle delay (bubble).

Question
A program consists of 40% ALU, 20% Load, and 40% Branch instructions. Suppose that each Load
instruction has a data dependency with an ALU instruction that immediately follows it in the
program execution causing a cycle delay (bubble). Each branch instruction causes always exactly a
cycle delay (bubble). Assume that without considering any of the delays the CPI is 1. What is the
actual CPI with the above delays?
