It is easy to make small mistakes when you are in a hurry. And, as always, you must do the pre-labs independently.
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. Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials. To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit.
You do not have to use the assembly program or the simulator. Assume that the output voltage is quiescent i. Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup!
Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. Your dztasheet shall meet the following requirements: For the questions involving 74ps374 running sum, you may find it faster to compute the sum using a formula for an arithmetic sequence, rather than doing the sum iteratively. Create a similar example using different, non-trivial e. Circuit Output Connections In the resistor network, each resistor is Ohms.
Put a brief comment at the beginning which describes the overall function of the code. The term counter limit refers to the maximum value the counter runs to e. This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another.

Why is it valid or invalid? The first instruction is done as an example. Machine code is fetched fatasheet memory and the instructions described are executed by the processor. Note that 74LS labeling of “Q” outputs is in terms of bus bits dataseet not per data sheet for this diagram. Paste a copy of the 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.
For this lab, you will adapt the string hash program from lab 1. For this lab, you will write a program that uses a dataasheet to add the numbers 1 through and displays the results. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. 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. This lab uses the same circuit as Lab 2 part A. You MUST follow these procedures or we will not accept your submissions. Think of how embarrassed you will be if you get something wrong datashset saying you followed the checklist.
DUAL 4-INPUT POSITIVE-NAND 50-OHM LINE DRIVERS
The point of this exercise is to actually follow all the steps on the checklist, not just say you followed datasgeet. You will connect the circuit and write a simple program to verify its operation. 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. Look carefully at the data sheet!
Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. Links to all files referenced dataasheet the lab and prelab can be found in the Datasueet section at the end of this document. All non-code parts of the hand-in should be submitted as a single document.
Limit your answer to 40 words. It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand.
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. Also, see the course materials repository page. Do this by hand using the reference materials. To familiarize yourself with the microcontroller assembly instructions and the process of assembly.
BUT, we expect both of you to understand and participate in the execution of both labs. Briefly comment each line to describe what it does 10 words or fewer per line. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes. Assume the voltage drop across the LED is 1.
When you record your answers, use the conventions described in the discussion section. Refer above for details on wiring the circuit.
For example, if Q7 is high, and Q6: For the questions in part B.
