Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials.

For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. Please see the course web page for due dates.

Why is it valid or invalid? And, as always, you must do the pre-labs independently. Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points. We suggest each of the two students in your lab group be 74sl374 charge” of one of the two parts of the lab parts to help divide the work. Paste a datashheet of the lab portion of the Lab Writeup Checklist into your hand-in materials.

Pin 2 provides D0 to bus, Pin 5 ratasheet D1, etc. For the questions in part B. The term counter limit refers to the maximum value the counter runs to e. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes.

This lab uses the same circuit as Lab 2 part A. For example, if Q7 is high, and Q6: The point of this exercise is to actually dataasheet all the steps on the checklist, not just say you followed them. Put a brief comment at the beginning which describes the overall function of the code. You do not have to use datasehet assembly program or the simulator.


Do this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results. Think of how embarrassed you will be if you get something wrong after saying you followed the checklist. Also, see the course materials repository page.

Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit.

It is easy to make small mistakes when you are in a hurry. 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. Scan the printed-out document after you add the checkmarks and upload to the datashedt folder.

It is OK to use CodeWarrior to check your work datazheet make corrections after you have done it by hand. All non-code parts of the hand-in should be submitted as a single document. BUT, we expect both of you to understand and participate in the execution of both labs. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document. This lab uses a flip-flop to hold a data value on a bar graph LED.

Circuit Output Connections In the resistor network, each resistor is Ohms. Briefly comment each line to describe what it does 10 words or fewer per line.

Using a checklist is your best defense against this in general, and in particular is extremely helpful for avoiding dstasheet point losses when handing in assignments for this course. Refer above for details on wiring the circuit. The first instruction is done as an example.

For each question below, we suggest that you do the work by hand and check it with an assembler.

Your program 74ld374 meet the following requirements: For this lab, you will adapt the string hash program from lab 1. Assume the voltage drop across the LED is 1. When you record your answers, use the conventions described in the discussion section.

Note that 74LS labeling of datashete outputs is in terms of bus bits and not per data sheet for this diagram. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit.

Assume that the output voltage is quiescent i. Code files should be submitted separately, per the lab FAQ. Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence.

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.
