Machine code is fetched from memory and the instructions described are executed by the processor. When you record your answers, use the conventions described in the discussion section.

BUT, we expect both of you to understand and participate in the execution of both labs. 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.
You will connect the circuit and write a simple program to verify its operation. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes. Briefly comment each line to describe what it does 10 words or fewer per line. The term counter limit refers to the maximum value the counter runs to e. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document.
Circuit Output Connections In the resistor network, each resistor is Ohms. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! For the questions in part B. For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. Refer above for details on wiring the circuit.
Please see the course web page for due dates. This lab uses a flip-flop to hold a data value on a bar graph LED. The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them. This lab uses the same circuit as Lab 2 part A. It is easy to make small mistakes when you are in a hurry. Paste a copy of the pre-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. And, as always, you must do the pre-labs independently. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials. Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit.
18-348 Lab #2
Embedded Hardware – Part B: Do this by hand using the reference materials. Look carefully at the data sheet! Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points. 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.
Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. For example, if Q7 is high, and Q6: The first instruction is done as an example. For this lab, you will adapt the string hash program from lab 1. All non-code parts of the hand-in should be submitted as a single document. It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand.
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? 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. Think of how embarrassed you will be if you get something wrong after saying you followed the checklist. Create a similar example using different, non-trivial e. Code files should be submitted dataasheet, 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. Pin 2 provides D0 to bus, Pin 5 provides D1, etc.
Your program shall meet the following requirements:
