PURPOSE: To provide the same multiplied result as the multiplication of '1'. CONSTITUTION: A DSP is composed of a coefficient register 10, selector A11, multiplier 12, comparator 13, selector B14, selector C15, adder 16, selector D17, temporary RAM 18, microprogram register 19, address register 20, address controller 21 and internal bus 22 or the like. When the output signal of the selector A11 is matched with a negative minimum value, the comparator 13 sends a select signal to the selector B14 so that an output signal from the temporary RAM 18 can be selected. |
