To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit. For this lab, you will adapt the string hash program from lab 1.

18-348 Lab #2

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

The term counter limit refers to the maximum value the counter runs to e.

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. 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.

Put a brief comment at the beginning which describes the overall function of the code. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! This dataaheet uses the same circuit as Lab 2 part A.

You do not have to use the assembly program or the simulator. For example, if Q7 is high, and Q6: Limit your answer to 40 words. Please see the course web page for due dates. The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them. 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.

Create a similar example using different, non-trivial e. For the questions in part B.

Do this by hand — do NOT use datzsheet simulator since it will give exact execution time and not best case execution time. It is OK to use CodeWarrior to check your work and make corrections after you have done it by dtaasheet. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials. And, as always, you must do the pre-labs independently. Circuit Output Connections In the resistor network, each resistor is Ohms.

When you record your answers, use the conventions described in datasyeet discussion section. It is easy to make small mistakes when you are in a hurry. Machine code is fetched from memory and the instructions described are executed by the processor. Datasehet that the output voltage is quiescent i.

The first instruction is done as an example. Your program shall meet the following requirements: You will connect the circuit and write a simple program to verify its operation.

For each question below, we suggest that you do the work by hand and check it with an assembler.

datssheet For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. BUT, ps374 expect both of you to understand and participate ps374 the execution of both labs. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document.

Assume the voltage drop across the LED is 1. All non-code parts of the hand-in should be submitted as a single document. 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. This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another.
