Question 1
Grade
1- Consider a machine with four instruction classes, whose CPI and code size (IC
i
) for each
instruction class for a program are given below:
(i) Find the execution time on a 3GHz processor.
(ii) What is the speedup if the number of ALU instructions can be reduced by one-quarter?

Question 2
Grade
Suppose that a new MIPS instruction, called bcp, was designed to copy a block of words from
one address to another. Assume that this instruction requires that the starting address of the
source block is in register $t1 and that the destination address is in $t2. The instruction also
requires that the number of words to copy be in $t3 (which is > 0). Furthermore, assume that
the values of these registers as well as register $t4 can be destroyed in executing this instruction
(so that the registers can be used as temporaries to execute the instruction).
a. Write the MIPS assembly code to implement a block copy without this instruction.
c. Estimate the total cycles necessary for each realization to copy 100-words on the multicycle
machine.
