1- Construct a 1-bit ALU that performs AND, OR, XOR, Addition & Subtraction operations. 4- Represent the 2 numbers X = 1502.75, Y = -2314.5 * 10-4 in single precision IEEE 754 bias notation, then perform the operations below (using appropriate algorithms): a. X* Y b. X+Y Show your steps in detail. Consider rounding to 4 digits. 3- Consider the two integer numbers 27 & -13, Calculate the results of dividing 27 by -13 using the signed division algorithm. Show your steps in detail. 2- Consider the two positive integer numbers 12 & 13, Calculate their Product using the Third version multiplication algorithm. Show your steps in detail
