A compiler designer is trying to decide between between three code sequences for a particular computer. The hardware designers have supplied the following table for CPI for three instruction classes: 2 3 The compiler designer is considering three code sequences that require the following instruction counts Code sequence A B C 2 3 In other words, code sequence 1 would require two A instruction classes, two B instruction classes and two C instructions classes. Which code sequence executes the least number of instructions? Code sequence 1 Code sequence 2 Code sequence 3
