You may submit this WebQuiz a total of 10 times and receive full credit. This quiz assumes your arithmetic unit structure is of the form shown in the arithmetic unit figure . In this question you will design a simple 12-bit Arithmetic Unit (AU), capable of computing any of four functions of A and B. The particular function to be computed will be selected according to the values of control variables j and k. Your AU should operate as specified in the following table: j k Operation Performed 0 0 A MINUS B 0 1 -B 1 0 A PLUS B 1 1 A' Assume that the numbers A and B are in 12-bit 2's complement form. The arithmetic unit will be constructed by expanding on the design of an ordinary 2's complement adder/subtractor. Specifically, the i th FA will have as input a i * and b i *, where a i * is the modified a i input, and b i * is the modified b
