Consider three different processors P1, P2 and P3 executing the same instruction set with clock rates and CPI given in the following table: Processor Clock Rate CPI P1 2 GHz 1.5 P2 1.5 GHz 1.0 P3 3 GHz 2.5 c) We are trying to reduce the execution time by 30% but this leads an increase of 20% in the CPI. What clock rate should we have to get this time reduction? b) If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions

Given the choice (complete freedom, monetary backing, etc.) what requirements gathering method would you tend to implement, and why?

how multiplication of two numbers (50 & 25) stored in RAM is carried out on the Cortex-M4 processor using the MUL instruction.

A. Create a Dollar currency class with two integer attributes and one string attribute, all of which are non-public. The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part. The string attribute will represent the currency name.

B. Create a CIS22C Dollar derived/inherited class with one additional non-public double attribute to represent the conversion factor from/to US Dollar.

• The value of the conversion factor can be defaulted in the class definition based on 1 USD = 1.36 C2D or 1 C2D = 0.74 USD.
• Also, 1000 of C2D fractional parts equals 1 C2D whole part.

C. In your two currency classes, add public methods for the following:

• Default Construction (i.e. no parameters passed)
• Construction based on parameters for all attributes
• Copy Constructor and/or Assignment, as applicable to your programming language of choice
• Destructor, as applicable to your programming language of choice
• Setters and Getters for all attributes
• Adding two objects of the same currency
• Subtracting one object from another object of the same currency
• Comparing two objects of the same currency for equality/inequality
• Comparing two objects of the same currency to identify which object is larger or smaller
• Print method to print details of a currency object
• In your derived class only, methods to convert USD objects to C2D and vice versa

D. Create a Wallet class with one attribute - an array of two Dollar references / pointers and the following methods to demonstrate polymorphism of the currencies:

• A default Constructor which sets
  • the first element of the array to a zero value Dollar object
  • the second element of the array to a zero value CIS22C Dollar object
• A Destructor, as applicable to your programming language of choice
• Methods to add or subtract
  • USD objects to/from the first element only and
  • C2D objects to/from the second element only
• Methods to compare if the value of either element is greater or smaller than an input value
• A method to Print the values of the two elements in the Wallet

E. In your main:

• Create a Wallet object
• Provide the user a main menu to add/ subtract/ compare the Dollar and CIS22C Dollar values in the Wallet as well as print the contents of the Wallet
• You can use a second level menu choice to allow the user to select currency type
• Based on user choice, create either UD or C2d objects as needed to perform the desired operations.
• The main menu should be run in a loop until the user selects the Exit option
• There is no sample output - you are allowed to provide user interactivity as you see fit and programs will be graded for clarity of interaction

uppose the following scenarios to discuss the impact effecting on the degree of multiprogrammingand context switching time?

Scenario1:all the processes in the ready queue are classified as I/O bound –process.

Scenario 2:All the processes in the ready queue are classified as CPU bound –process.

Scenario 3:Most of the processes in the ready queue are classified asmix of I/O bound –processes and CPU-bound processes

};

Give declatations of operator functions for each of the following ways to overload operator + You must state where the declatation goes, whether within the class in the public or private section or outside the class. The operator + may be overloaded. a) as friend function b) as member function c) as non-friend, non-member function

In order to achieve faster access to data, many I/O operations involve specific data structure class called "Buffer". Our goal in this question is to design a UML class diagram for a character buffer (an array of chars ) based on the following description. This particular buffer:

1. has the name charBuffer
2. has a definite size
3. has an indicator whether it is empty or not
4. has an indicator whether it is full or not
5. has write to buffer operation
6. has read from buffer operation
7. has delete buffer operation
8. has check for emptiness operation
9. has check for fullness operation

Using SQL create a new database called school_app. Create a student table with fields id (auto increment), first_name, last_name. Create a course table with fields id (auto increment), course code (such as ITC or MTH), and course number (such as 100 or 295). Note that the relationship between student and course is many-to-many (n:m). Create a join table called student_course that implements the n:m relationship with fields id (auto increment), student_id, course_id, and grade (which has values 0, 1, 2, 3, or 4). Insert data into all the tables with at least 10 different students and at least 3 different courses (you must be one of the students). Make sure all the students are taking multiple courses and all courses have multiple students. Do not use the data from anyone else in this course. When finished, do a SELECT * for all three tables and copy/paste the results here:

If someone could help me with this, it would be greatly appreciated. Ill certainly give a thumbs up!

Assignment 2 (worth 10% of the final course grade - due date July 23, 2019) Prof. Sherif Saad Purpose The purpose of this assignment is to help you to practice working with C String, arrays, and pointers Learning Outcomes ● Develop skills with pointers ● Learn how to traverse C String using pointers ● Passing Strings to functions ● Manipulate C String ● Develop algorithm design skills Problem Overview You will implement a basic string manipulation library called xstring.h. This library provides the ability to manipulate and search native C strings. The library offers the following functions int FindFirstOccurrence(char c , char *pStr ); //[5 Points] /* This function takes two parameters the first is a variable of type char and the second is a pointer of type char that point to a string variable. The function will parse the string and return the index of the first occurrence of the char variable in the string. If the character does not exist, it will return -1 example pStr = "Hello World!" c = 'o' The function will return 4, because the first o occurred at index 4 in the string */ int FindLastOccurrence(char c, char * ); //[5 Points] /* This function takes two parameters the first is a variable of type char and the second is a pointer of type char that point to a string variable. The function will parse the string and return the index of the last occurrence of the char variable in the string. If the character does not exist, it will return -1 University of Windsor COMP141- Summer 2019 School of Computer Science example pStr = "Hello World!" c = 'o' The function will return 7, because the last o occurred at index 4 in the string */ int GetStringWeight (char *pStr ); // [10 Points] /* This function takes one parameter, which is a char pointer variable that points to a C string. The function will calculate and return the weight of the C string. The weight of the C string is the total sum of the ASCII code representation of the characters in that string. example pStr = "Cat" The function will return 280 since ASCII('C') = 67, ASCII('a') = 97 , and ASCII('t') = 116 */ void ReplaceCharacter(char x , char c , char * pStr); // [10 points] /* This function takes three parameters the first and the second are variables of type char, and the third is a pointer of type char that point to a string variable. The function will parse the string using pStr and every time it finds a character that matches the value of x it will replace it with the value stored in c. example pStr = "banana and apple" x = 'a' c = 'e' The function will change pStr to "benene end epple" */ University of Windsor COMP141- Summer 2019 School of Computer Science void ToUpperCase(char * pStr); // [10 points] /* This function takes one parameter, which is a char pointer variable that points to a C string. The function will convert all the lower case alphabetic characters to uppercase characters. example pStr = "The Cat in The Hat" The function will change pStr to "THE CAT IN THE HAT" */ void ToLowerCase(char *pstr); // [10 points] /* This function takes one parameter, which is a char pointer variable that points to a C string. The function will convert all the uppercase alphabetic characters to lowercase characters. example pStr = "COMPUTER" The function will change pStr to "computer" */ void RemoveCharacter(char c , char str[] ); // [15 points] /* This function takes two parameters the first is a variable of type char and the second is a char array that store to a C string. The function will parse the C string and remove any character in the string that matches the character value stored in c example str = "Cats Hats Tags" c = 's' The function will change str to "Cat Hat Tag" */ University of Windsor COMP141- Summer 2019 School of Computer Science void ReverseString(char *pStr); // [15 points] /* This function takes one parameter, which is a char pointer variable that points to a C string. The function will reverse the string. example pStr = "Pass the test" The function will change pStr to "tset eht ssaP" */ Instructions You will use the provide code skeleton to complete the assignment. The code skeleton consist of three files. These three files are main.c, xstring.c and xstring.h. The main.c conatins the main program that allows the user to enter any string and characters to manipulate using the xstring library. The xstring.h file contains the function prototypes of the xstring library. Finally, the xstring.c file contains the implementation (function definition) of the xstring library. You are required to: 1. Complete the implementation of the functions and fix any existing bug in the code functions [80 points] 2. Link the main.c file and the xstring.c file using the xstring.h file as shown the lecture notes, please see lecture 3 [10 points] 3. Compile and run the main to test your implementation [10 points] IMPORTANT NOTES: 1. You can create any additional function you think they are necessary to implement the xstring library. 2. You should NOT use any built-in function from the C String library (e.g strlen, strcpy, etc)

Discuss the difference between the IP, DNS and MAC addresses – how do the relate to one another in a network?

Using Visual Studio write a program that allows the user to enter multiple scores ranging from 0 to 100, computes the average of

those scores and then writes out a letter grade using the typical grading scale. Your program will also:

1. Allow the user to enter any number of scores he or she wishes but assume there will be at least one

score entered.

2. Use a sentinel-controlled loop variable to terminate the loop when the user has no more scores to

enter. Hold user in a loop if a “yes” or “no” is not entered.

3. Use the TryParse method, to hold the user in a loop if a non-numeric value is entered. To exit the loop,

the user must enter correct input.

4. Hold the user in a loop if a value less than 0 or greater than 100 is entered.
