1. Assume we have the following MIPS code, starting at memory address

1000H:

1000H	LOOP:	slt	$t2, $zero, $t1
1004H		beq	$t2, $zero, DONE
1008H		subi	$t1, $t1, 1
100CH		addi	$s2, $s2, 2
1010H		j	LOOP
1014H	DONE:

If we use PC relative addressing, what is the constant for DONE in the beq instruction?

a. This processor has a clock rate of 2 GHz, and the average cycles per instruction is 2. The processor is tested on a SPEC benchmark program that has 109 instructions. What is the execution time for this program on this processor?

b. This processor has a clock cycle time of 2 ns. When the processor runs the same SPEC benchmark program of Problem 1, the resultant execution time is 8 seconds. What is the average CPI for this processor?

c. You have a base machine that has a uniprocessor. Your software development team has developed an application for a dual-core processor. The application is 40% parallelizable (that is, 40% of the execution time is spent in the parallel unit). How much speedup would you achieve with this application, with respect to the base machine?

3 a. We are given a CMOS logic gate with activity factor of 0.25 and supply voltage of 5 V. The logic gate is driving a load of 200 fF at a clock frequency of 2 GHz. What is the dynamic power dissipation of this logic gate?

4.

The Testing Department has reported that our corporate server system has an FIT of 1000.

a. What is the MTTF (hours) for this system?

If it takes 4 days to get the system running again, what is the availability of the system? Please show your answer to 6 significant digits after the decimal

point.
