Is a real voltage source.
The current machine, codenamed "Jaguar," has a clock rate of 2GHz. The hardware team claims that it can improve the clock rate to 2.5GHz. The codename for this improved machine is Jaguar-EH. Specs for both machines are shown in Table 1 below. A standard practice in the computer industry is to perform extensive simulations of new designs before producing them. For instance, we can run a series of benchmark programs on a simulator for a new processor and make valuable measurements. Such a study yielded the data shown in the last two columns for Jaguar-EH:
Table 1: Specs for Jaguar and Jaguar-EH.
Instruction Type | CPI for Jaguar | CPI for Jaguar-EH | Frequency of Instruction Type in the benchmark
A | 3 | 4 | 40%
B | 6 | 2 | 20%
C | 4 | 6 | 10%
D | 4 | 5 | 20%
E | 2 | 3 | 10%
a. (8 points) Calculate the average CPI and MIPS ratings for Jaguar.
b. (8 points) Calculate the average CPI and MIPS ratings for Jaguar-EH.
c. (8 points) How much faster is Jaguar-EH compared to Jaguar?
