Why is it valid or invalid? Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! Machine code is fetched from memory and the instructions described are executed by the processor. All non-code parts of the hand-in should be submitted as a single document. This lab uses the same circuit as Lab 2 part A. 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.

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

Embedded Hardware – Part B: Look carefully at the data sheet! Refer above for details on wiring the circuit. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes. The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them.

Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram.

For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. When you record your answers, use the conventions described in the discussion section. This lab uses a flip-flop to hold a data value on a bar graph LED. You do not have to use the assembly program or the simulator. Code files should be submitted separately, per the lab FAQ. Assume that the output voltage is quiescent i. Think of how embarrassed you will be if you get something wrong after saying you followed the checklist.

For the questions in part B. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document.

It is OK to use Ls34 to check your work and make corrections after you have done it by hand. Limit your answer to 40 words. Do this by hand using the reference materials.

Do this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time. For example, if Q7 is high, and Q6: For each question below, we suggest that you do the work by hand and check it with an assembler. The term counter limit refers to the maximum value the counter runs to dahasheet. Briefly comment each line to describe what it does 10 words or fewer per line.

Scan datashedt printed-out document after you add the checkmarks and upload to the hand-in folder.


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. Assume the voltage drop across the LED is 1. To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit. Adtasheet this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results. Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials.

Pin 2 provides D0 to bus, Pin 5 provides D1, etc. It is easy to datzsheet small mistakes when you are in a hurry. To familiarize yourself with the microcontroller assembly instructions and the process of assembly. This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another. Put a brief comment at the beginning which describes the overall function of the code.

Please see the course web page for due dates. And, as always, you must do the pre-labs independently. Also, see the course materials repository page. BUT, we expect both of you to understand and participate in the execution of both labs.

Ls37 MUST follow these procedures or we will not accept your submissions. Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points.

The first instruction is done as an example. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials.

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