Limit your answer to 40 words. You MUST follow these procedures or we will not accept your submissions. Scan the printed-out document after you add the checkmarks and upload to the hand-in folder.
Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another. Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points.
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. Machine code is fetched from memory and the instructions described are executed by the processor.
Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. Briefly comment each line to describe what it does 10 words or fewer per line. To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit.
Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials. Think of how embarrassed you will be if you get something wrong after saying you followed the checklist. It is easy to make small mistakes when you are in a hurry. The first instruction is done as an example.
Do this by hand using the reference materials.
18-348 Lab #2
We suggest each of the two students in your lab dattasheet be “in charge” of one of the two parts of the lab parts to help divide the work. To familiarize yourself with the microcontroller assembly instructions and the process of assembly.
Assume the voltage drop across the LED is 1. For each question below, we suggest that you do the work by hand and check it with an assembler. This lab uses the same circuit as Lab 2 part A. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! Code files should be submitted separately, per the lab FAQ. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.

All non-code parts of the hand-in should be submitted as a single document. The term counter limit refers to the maximum value the counter runs to e. You do not have to use the assembly program or the simulator. Refer above for details on wiring the circuit. For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly dagasheet. Embedded Hardware – Part B: Why is it valid or invalid?
For example, if Q7 is high, and Q6: When you datashedt your answers, use the conventions described in the discussion section.
Daasheet will be expected to assemble, disassemble, and time code by hand on tests and quizzes. Your program shall meet the following requirements: For this lab, you will adapt the string hash program from lab 1. 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.
This lab uses a flip-flop to hold a data value on a bar graph LED. Assume that the output voltage is quiescent i.
And, as always, you must do the pre-labs independently. BUT, we expect both of you to understand and participate in the execution of both labs.
Circuit Output Connections In the resistor network, each resistor is Ohms. It is OK to use CodeWarrior to check your work and make corrections le374 you have done it by hand. Please see the course web page for due dates.
Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials. Do this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time. Using a lss374 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. Put a brief comment at the beginning which describes the overall function of the code. Also, see the course materials repository page.
For the questions in part B.

Pin 2 provides D0 to bus, Pin 5 provides D1, etc. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document. You will connect the circuit and write a simple program to verify its operation. Look carefully at the data sheet! Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram.
