Relative Speed of Ripple Carry Adders

Calculate the relative speed of a 64-bit adder using ripple carry only, a ripple carry of 4-bit groups that use carry lookahead, and a ripple carry of 16-bit groups that use carry lookahead. Use the simulator located at the following url: http://www.ecs.umass.edu/ece/koren/arith/simulator/ Also explain, what is relative spee

probability of a Line in a Switch Board

Consider a (n x k) crossbar switch with k < n. Suppose the probability of a line being in use is p. What is the probability that the switch is blocked for the next caller? a. 1-(1-p)^(n-k) b. (n!/(k!*(n-k)!))*p^k c. (p^k)*(1-p)^(n-k) d. Sum(j=1,k)((n!/(j!*(n-j)!))*p^j

Output for values

4. Consider the following program in Pascal with static scope: program main (input, output); var i, j, k, m: integer; procedure Q (var i: integer; m: integer); begin i := j + 1; m := k + 1; writeln (i, j, k, m); end procedure P(var i: integer; j: integer); var k: integer; procedure S(i: integer) begin i := k + 3; m

If there's no foreign keys, pls. give one foreign key each for the situation. Thank you in advance. 1. One-to-One: Man (man_name, man_age, man_

Thread Synchronization

C program that runs under cygwin which again declares three pthreads. The main program prompts the user for the values x, y, z all integers. It then starts the threads. Thread1 calculates the average of x, y and z and puts the value into a shared variable w. Thread2 calculates the product and puts the value into v. Th

Threads

C program that creates three pthreads, each of which executes a different slave process. The first slave prompts the user for two integers x and n and the uses a loop to calculate xn and outputs the result. The second slave outputs the phrase "Hello from slave 2" ten times inside the nested for loops For(I=0; i<10
