Problem 1: Write a function add64 that adds two input unsigned 64 bit integers x and...
computer architecture The sum of the two 32 bit integers may not be representable in 32 bits. In this case, we say that an overflow has occurred. Write MIPS instructions that adds two numbers stored in registers Ss1 and Ss2, stores the sum in register $s3, and sets register Sto to 1 if an overflow occurs and to 0 otherwise. 5. (16pts) 6. Show the IEEE 754 binary representation of the number -7.425 in a single and double 7. If...
10.11 (Left Shifting Integers ) Left shifting an unsigned int by 1 bit is equivalent to multiplying the value by 2. Write function power2 that takes two integer arguments number and pow and calculates number * 2pow. You should declare pow as an unsigned integer , but remember that the result may be a negative value . Use the shift operator to calculate the result. Print the values as integers and as bits . Assume that an integer is of...
Write code to implement the following function: /* * Generate mask indicating leftmost 1 in x. Assume w=32. * For example 0xFF00 -> 0x8000, and 0x6600 --> 0x4000. * If x = 0,then return 0. */ int leftmost_one(unsigned x); Your function should follow the above bit-level integer coding rules, except that you may assume that data type int has w=32 bits. Your code should contain a total of at most 15 arithmetic, bit-wise, and logical operations. In C++ and has...
Problem 1 Write a find subroutine that can locate a specified 8-bit quantity in a null-terminated string 8-bit quantities. (Remember that null terminated means "it ends with zero"). The subroutine is passed two parameters. The pointer to the array is passed in array X, the value to be found is passed in ACCA. The function should return the index of the first occurrence of the value in ACCB, or -1 (0xFF) if the value is not found. a) Write the...

PROBLEM STATEMENT The mini-calculator will use a small ALU to perform arithmetic operations on two 4-bit values which are set using switches. The ALU operations described below are implemented with an Adder/Subtractor component. A pushbutton input allows the current arithmetic result to be saved. An upgraded mini-calculator allows the saved value to be used in place of B as one of the operands. The small ALU that you will design will use the 4-bit adder myadder4 to do several possible...
C++ Problem 1 Write a function to calculate the greatest common divisor (GCD) of two integers using Euclid’s algorithm (also known as the Euclidean algorithm). Write a main () function that requests two integers from the user, calls your function to compute the GCD, and outputs the return value of the function (all user input and output should be done in main ()). In particular, you will find this pseudocode for calculating the GCD, which should be useful to you:...
RecursiveExponent.java Write a recursive function that accepts two arguments into parameters x and y, and which returns the value of x raised to the power y. Hint: exponentiation is equivalent to performing repetitions of a multiplication. For example, the base 4 raised to the 6th power = 4*4*4 * 4 * 4 * 4 = 4,096. The only file that you need to create is RecursiveExponent.java. Your main method should prompt the user to supply the base and exponent values...
Q1. Write a recursive function in C++ void printNumberedChars(string str, int i=0) { ... } which prints each character of the given string str on a new line, with each line numbered 1, 2, 3, …. For example calling the function with printNumberedChars("hello"); should output the following: 1. h 2. e 3. l 4. l 5. o Q2. Write a recursive function in C++ int sumArray(const int* arr, unsigned int size) { ... } which takes an array of integers,...
Question 1 An array is NOT: A - Made up of different data types. B - Subscripted by integers. C - A consecutive group of memory chunks. D - None of the choices. Question 2 How many times is the body of the loop executed? int i=1; while(true) { cout << i; if(++i==5) break; } A - Forever B - 4 C - 5 D - 6 E - 0 Question 3 What is wrong with the following piece of...
