Abstract: the main purpose of this experiment is build real time system using PPI 8255 to control devices connected to. Problem description: assume that there are two devices are connected to port A and two sensors are connected to port B of PPI 8255. They work according to the following table Devices (DID2) 01 10 Sensors (S1S2) 00 01 10 11 11 00 Write a program to control these two devices according to the values of sensors. Each group should submit a zip file which contains the following files Code file: (assembly language code) - Simulation file Report (pdf file) (details of every single step in the code, also what have you learned from this experiment)
Instrument FrequencyCounter to use Stopwatch and StdDraw to make a plot where the x-axis is the number of calls on get() or put() and the y-axis is the total running time, with a point plotted of the cumulative time after each call. Run your program for Tale of Two Cities using SequentialSearchST and again using BinarySearchST and discuss the results. Note : Sharp jumps in the curve may be explained by caching, which is beyond the scope of this question.
A binary operator is an operation that is performed on two operands. For example, addition is a binary operator that adds two operands (e.g., 2 + 4). In the provided UML diagram, all binary operators have two operands and an execute method that performs the appropriate operation on the operands. The AddOperation class should add the two operands. The SubtractOperation class should subtract the two operands. Here is an example of how a binary operator could be used: IBinaryOperator operator = new AddOperator(8, 12);System.out.println(operator.execute()); // should print 20operator.setLeftOperand(18);System.out.println(operation.execute()); // should print 30 crate a Main.java to test your code
Assignment 4 In this assignment, you will implement your own interpreter pattern to check a given sentence complies with the sentence requirements given below. Your implementation make sure to do necessary corrections on the sentence. Sentence Requirements: • Every sentence starts with a capital letter. • No sentence can start with a number. • Every sentence ends with a period “.”. • No consecutive words can be same. An exemplary sentence and its corrected version: “ 1 this is is a a sample sentence” Corrected sentence: “This is a sample sentence.” Deliverable: Your Java source code with appropriate design and classes/interface(s).
Write a C program which creates two childprocesses. One of the child processes mustopen data1.txt and fill it with 10 randomintegers (0-9). The other child process mustopen data2.txt and fill it with 10 randomletters (a-z). In the meanwhile, parent mustprint both child processes' id's and wait forthem to finish.
A parent process calls fork creating a child and continues running but does not call wait. The child calls fork itself and immediately exits (without calling wait), while it's child (the grandchild of the first process) continues running. At this point which of the following correctly describes the situation. The child and the grandchild both become orphans. The child becomes and orphan and the grandchild becomes a zombie. The child becomes a zombie and the grandchild becomes an orphan. The child and the grandchild both become zombies.
In Python Programming language USING AVL TREE Building an automatic appointment reservation system for a very busy heart surgeon in the city. The system is going to work as follows: The patient requests for an appointment time. The system looks through the list of appointments and if there are no appointments scheduled within 10 minutes either way of the requested time, then that appointment is added to the list of appointments along with the patient ID. Otherwise, the patient is given the next available time automatically that is not within 10 minutes of any other scheduled appointment. At the appointed time, the appointment is marked as serviced and deleted from the list of appointments. You must use an AVL Tree to implement this appointment system. The reservation system should run as follows: It should run for a total of 12*25*60 minutes. At each time instant, there is a 10% probability that a new request comes in. If a new request comes in, generate a random number between the…
Develop a shopping solution that has both client side and server side. Server-side ⚫ A console application should be enough, it prints each response to the output window before sending back to the client-side(s). • When it first runs, at least five pre-defined products with random quantities (1-3) should be initialized. Which means products should be the same every time the server starts, and the quantities for each product should be randomized. At least 3 accounts should be created, each account has an account number and user's name. • When the server is active, it should store ordering information to variable(s) (e.g., dictionaries, lists). The server does not have to store the ordering information to the local system, so once you shutdown the server, all information can be disposed. • Server should send back appropriate response depending on the client's command. (Protocol below) • The handler code should be separated from the user interface (i.e., in a separate class - similar to…
IN JAVA Alice and Bob are playing a board game with a deck of nine cards. For each digit between 1 to 9, there is one card with that digit on it. Alice and Bob each draw two cards after shuffling the cards, and see the digits on their own cards without revealing the digits to each other. Then Alice gives her two cards to Bob. Bob sees the digits on Alice’s cards and lays all the four cards on the table in increasing order by the digits. Cards are laid facing down. Bob tells Alice the positions of her two cards. The goal of Alice is to guess the digits on Bob’s two cards. Can Alice uniquely determine these two digits and guess them correctly? Input The input has two integers p,q (1≤p<q≤9) on the first line, giving the digits on Alice’s cards. The next line has a string containing two ‘A’s and two ‘B’s, giving the positions of Alice’s and Bob’s cards on the table. It is guaranteed that Bob correctly sorts the cards and gives the correct positions of Alice’s cards. Output If Alice can…
Order check [15 points]. Write a program OrderCheck.java that takes four int command-line arguments w, x, y, and z. Define a boolean variable whose value is true if the four values are either in strictly ascending order (w < x < y < z) or strictly descending order (w > x > y > z), and false otherwise. Then, display the boolean variable value.NOTE 1: Do not use if statements on this program.NOTE 2: Assume that the inputs will always be integers.
Computer Science Implement RSA encryption and decryption functions in Java. Note you should not use any existing security modules to perform the encryption/decryption tasks. Just write a program to compute the answers. Your program should ask user’s input for a public key (n, e), and for Q1 ask for m and display c; and ask for c and display private key d and original message m.
Q2: Secret Courses Dan’s recently announced that he’s teaching n top-secretcourses nextsemester. Instead of enrolling in them through ACORN, students need to email Dan to express theirinterests. These courses are numbered from 1 to n in some arbitrary order. In particular, if a student named s is interested in taking a course c, they need to send an email to Dan containing the message c s. Note that if a student is interested in taking multiple courses, they need to send multiple emails, one per course. Upon receiving a message c s, Dan looks at the list of students already enrolled in course c. If there’s already a student on the list whose name is too similar to s, Dan assumes s is the same student and ignores the message. Otherwise, he enrolls s in the course. Dan considers two names too similar if and only if they have the same length and differin at most one letter(note that“a” and “A” are considered the same letter). For example, “Josh” and “Josh” are too similar. “Sam” and “CaM”…
