1. Write a CISC program to compute x-z-2 2. Show the steps in multiplying 12 and 15 in its binary form using the traditional multiplication algorithm of unsigned numbers. 3. Write a ALP to find the sum of negative and odd integers between 1 and a given number. Write its equivalent RTD. Draw the Wilkes Design Architecture for the same. Also, write its equivalent Vector Code. 4. Write a Register Transfer Description (RTD) for generating the sum of the square and the cube of a number. List the corresponding control points and draw its equivalent state diagram.
