Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes according to their CPI (class A, B, C, and D). P1 with a clock rate of 3GHz and CPIs of 1, 2, 2, and 3, and P2 with a clock rate of 4 GHz and CPIs of 2, 3, 1, and 2.
Given a program with a dynamic instruction count of 1.0E6 instructions divided into classes as follows: 10% class A, 20% class B, 50% class C, and 20% class D, which implementation is faster?
1.7 Compilers can have a profound impact on the performance of an application. Assume that for a program, compiler A results in a dynamic instruction count of 1.1E9 and has an execution time of 1.3s, which compiler B results in a dynamic instruction count of 1.3E9 and an execution time of 1.5s.
1.14 Assume a program requires the execution of 60 X 10^6 FP instructions, 100 x 10^6 INT instructions, 80 X 10^6 L/S instructions (load and store instructions), and 16 X 10^6 branch instructions. The CPI for each type of instruction is 2, 1, 3, and 4, respectively. Assume that the processor has a 2 GHz clock rate.
1.16 Convert the following binary numbers to decimal numbers, show the steps of your work.
