1. Using a N-bit adder, design the following N-bit comparators. A comparator's output is 1 if the condition is met, 0 otherwise. a. greater than (A > B, where A and B are N-bit signed integers).
b. smaller or equal (A <= B)
Sketch and submit your schematics for these two circuits. Schematics can be hand-drawing and then scanned into PDF for submission, or using Digital.
2. Using (System) Verilog design the 32-bit ALU as discussed in class but with an additional output 'Zero' that is 1 when all bits of the output Y is O. Write a testbech to test your design.
3. Design and test a 4-bit rotator that has two inputs: A and rotamt, and two outputs Yleft and Yright using (System) Verilog. The rotation amount (number of bits to be rotated) is given in rotamt and the output of left and right rotation will be in Yleft and Yright, respectively.
