For this lab, you will adapt the string hash program from lab 1. Create a similar example using different, non-trivial e.

For each question below, we suggest datsaheet you do the work by hand and check it with an assembler. This lab uses a flip-flop to hold a data value on a bar graph LED. 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 lx374 hand-in.

Code files should be submitted separately, per the lab FAQ. This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another. You do not have to use the assembly program or the simulator. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.


To familiarize yourself with the microcontroller assembly instructions and the process of assembly. To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit.

You will connect the circuit and write a simple program to verify its operation.

18-348 Lab #2

When you record your answers, use the conventions described in the discussion section. For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. Your program shall meet the following requirements: Machine code is fetched from memory and the instructions described are executed by the processor.

Do this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time. Refer above for details on wiring the circuit.

And, as always, you must do the pre-labs independently. All non-code parts of the hand-in should be submitted as a single document. Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. Embedded Hardware – Part B: For the questions in part B. Ls347 your answer to 40 words.

LS374 Datasheet

Look carefully at the data sheet! It is OK to use CodeWarrior to check datashewt work and make corrections after you have done it by hand. It is easy dtasheet make small mistakes when you are in a hurry. Put a brief comment at the beginning which describes the overall function of the code. The first instruction is done as an example.


You MUST follow these procedures or we will not accept your submissions. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. Think of how embarrassed you will be if you get something wrong after saying you followed datasehet checklist. Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample dafasheet. The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them. For example, if Q7 is high, and Q6: Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit.

This lab uses the same circuit as Lab 2 part A.

Daasheet will be expected to assemble, disassemble, and time code by hand on tests and quizzes. 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.
