Assume that the output voltage is quiescent i. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup!

Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes.

Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. Look carefully at dataseet data sheet!

Do this by hand using the reference materials. You do not have to use the assembly program or the simulator. To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit.

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. You will connect the circuit and write a simple program to verify its operation. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.

Briefly comment each line to describe what it does 10 words or fewer per line. The first instruction is done as an example. Create a similar example using different, non-trivial e. Put a brief comment at the beginning which describes the overall function of the code.

Dtasheet example, if Q7 is high, and Q6: Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. It is easy to make small mistakes when you are in a hurry.

Circuit Output Connections In the resistor network, each resistor is Ohms. This lab uses the same circuit as Lab 2 part A. Please see the course web page for due dates.

For the questions in part B. Why is it valid or invalid?

The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them. You MUST follow these procedures or we will datasheft accept your submissions.

This lab uses a flip-flop to hold a data value on a bar graph LED. 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. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. To familiarize yourself with the microcontroller assembly instructions and the process of assembly.

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. Do this 74s374 hand — do NOT use the simulator since it will give exact execution time and not best case execution time.

For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. 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.

Machine code is fetched from memory and the instructions described are executed by the processor.

For each question 7l4s374, we suggest that you do the work by hand and check it with an assembler. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document.
