A 16-Bit Scientific Calculator

A 16-bit calculator system is designed according to the following specifications. The calculator should perform the following unsigned arithmetic operations. Figure 1 shows the four basic modules of the calculator: • Addition (+), subtraction (-), Multiplication (*), division (/), and Power (X^Y). • The calculator should perform the following Bitwise Logical operations: ANDing (&), ORing (||), XORing ( ), complementing. • The calculator should perform the following Trigonometric functions: Sin(x), cos(x), tan(x). • The calculator takes two 16-bit integer operands only. • The user can select one of these operations from a list of items (numbered from 1-11). • The program should run in the video mode (the black screen – DOS Screen). • The operands are BCD numbers ranging from 0-999.
