Lab 3 MIPS Arithmethic Instructions
=====================================

Assignment 1
------------
Workout a binary (!) multiplication of 0x59 and 0x14. Give the complete multiplication,
not just the answer.

Workout the following binary division: 35 (base 10) / 8 (base 10). Show all steps of the binary
division. Use a binary point notation.

Workout a single precision IEEE notation for the division result. Do the same for a double
precision.

Assignment 2
------------
Use the singlecycle architecture of the previous lab in the SIM-PL executer.
Write a short assembly program which multiplies two integers using the MULT statement. How
can you retrieve the result? Look up the statements for this.

Write a program which implements figure 3.5 of Patterson and Hennessy. 

Compare the CPI of both programs

Assignment 3
-------------
Use the multiplier component of Multiplier.zip. Open this component in the executer.
Open in the program window the Multiplier.sal file. 

Investigate the component by changing multiplicand and multiplier. Note that he values
have a different base.

What can you say about the CPI on one multiply instruction?

if the SingleCycle architecture of the previous lab would be extended with this hardware
multiplier as a block near the ALU what will it mean for control lines and datalines?

What is the effect on the Cycle time of the architecture extension?

Lookup the opcode/func fields for the MULT instruction. Describe how to produce a
controlbit to select the multiplier. 

ALU and multiplier share the same datapath to the register file. Describe how you would
solve this.
