Consider the single-cycle 8-bit data path shown below. The A/B-buses carry operand data from internal registers, and the R-bus carries result data to be stored into internal registers. The control unit drives 3-bit register select lines for each bus, sets the ALU function, and so on. Here is a list of possible op-codes (destination operand first): In the table below, the control signals needed to perform specific operations are shown; 0,1 and X are used to indicate assertions and don't care conditions where appropriate. For each row a-h, indicate the full instruction
