This lab uses a flip-flop to hold a data value on a bar graph LED. Please see the course web page for due dates. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! Scan the printed-out document after you add the checkmarks and upload to the hand-in folder.

Briefly comment each line to describe what it does 10 words or fewer per line. Put a brief comment at the beginning which describes the overall function of the code.

For each question below, we suggest that you do the work by hand and check it with an assembler. Also, see the course materials repository page.

Using a checklist is your best defense against this in general, and in particular is extremely helpful for avoiding unnecessary point losses when handing in assignments for this course.

The term counter limit refers to the maximum value the counter runs to e.

We suggest each of the two students in your lab group be “in charge” of one of the two parts of the lab parts to help divide the work. For example, if Q7 is high, and Q6: Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials.

You MUST follow these procedures or we will not accept your submissions. This lab uses the same circuit as Lab 2 part A.

Create a similar example using different, non-trivial e. Pick an instruction where the exact execution time differs from the best datqsheet execution time and explain why in one sentence. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials. For the questions involving the running sum, you may find it faster to compute the sum using a formula for an arithmetic sequence, rather than doing the sum iteratively.

Assume the voltage drop across the LED is 1. Your program shall meet the following requirements: For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. Confirm the operation using the simulator to make sure you got it right, which you need document only by saying “checked with simulator” in your hand-in. Code files should be submitted separately, per the lab FAQ. For this lab, you will adapt the string hash program from lab 1.

To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit. Why is it valid or invalid? Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. Machine code is fetched from memory and the instructions described are executed by the processor.

Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram. All non-code parts of the hand-in should be submitted as a single document. It is easy to make small mistakes when you are in a hurry. When you record your answers, use the conventions described in the discussion section.

Refer above for details on wiring the circuit. For the questions in part B. And, as always, you must do the pre-labs independently. Think of how embarrassed you will be if you get something wrong after saying you followed the checklist. It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand.
