Draw the control unit and datapath for the following algorithm that returns an integer value. The function takes two points (x1, y1) and (x2, y2) and computes the equation for a line. It then evaluates and returns ynew for the parameter xp using that line. Use a 16-bit data bus. Show your work; label and clearly mark your diagram. Do not implement this in VHDL. int PredY(int x1, int y1, int x2, int y2, int xp) { int m, b, ynew; if (x1 – x2) <> 0 { m = (y1 - y2) / (x1 - x2); b = y1 - m * x1; ynew = m * xp + b; return(ynew); } else { return(65535); // that's a 16-bit FFFF } }
