1. Consider the expression: (A 1) (A2)(A B)(A B C)(ABC 1)(A B C - 1)(D E)/(A B)(A- B- C)) Assuming a simple three-operand format with instructions ADD, SUB, MULT and DIV (and that all data is in registers), write the assembly language code to implement this expression with the minimum data dependency (assuming that dependency extends to the next instruction only)
