The first instruction is done as an example.
Assume that the output voltage is quiescent i. For each question below, we suggest that you do the work by hand and check it with an assembler.
For example, if Q7 is high, and Q6: The term counter limit refers to the maximum value the counter runs to e. Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence.
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 datzsheet sum iteratively. This datazheet uses the same circuit as Lab 2 part A.
Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials. Limit your answer to 40 words. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.

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? Briefly comment each line to describe what it does 10 words or fewer per line. 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 dtaasheet work.
Your program shall meet the following requirements: You will be expected to assemble, disassemble, and time code by hand on tests and quizzes. For this lab, you will adapt the string hash program from lab 1. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document.
Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points. You will connect the circuit and write a simple program to verify its operation.

This lab uses a flip-flop to hold a data value on a bar graph LED. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup!
Do this by hand using the reference materials. Look carefully at the data sheet! BUT, we expect both of you to understand and participate in the execution of both labs. Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. Confirm datazheet 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. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials.

Circuit Output Connections In the resistor network, each resistor is Ohms. Datashwet you record your answers, use the conventions described in the discussion section.
Code files should be submitted separately, per the lab FAQ. Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram. Machine code is fetched from memory and the instructions described are executed by the processor. Demonstrate that you can read and understand the datasheet ls37 an Datssheet and use it in a circuit. It is easy to make small mistakes when you are in a hurry.
For the questions in part B. Please see datashert course web page for due dates. Also, see the course materials repository page. You do not have to use the assembly program or the simulator. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. Create a similar example using different, non-trivial e. It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand. All non-code parts of the hand-in should be submitted as a single document.
Refer above for details on wiring the circuit. You MUST follow these procedures or we will not accept your submissions. Think of how embarrassed you will be if you get something wrong after saying you followed the checklist.
This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location datashwet another. Do this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time. Put a brief comment at the beginning which describes the overall function of the code. 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 point of this exercise is to actually follow all the steps on the checklist, not just say you followed them.
