ABSTRACT:
In a digital signal processing system, a logarithmic arithmetic logic unit is provided which selectively performs multiply/accumulate operations of operands in logarithmic number representation. Direct feed through of operands through an adder/subtractor circuit, even when an addition or subtraction is not effected, eliminates external bypass circuitry. A method for adding and subtracting operands in logarithmic number representation is provided. An adder/subtractor circuit which efficiently effects addition and subtraction of operands in logarithmic number representation over a wide dynamic range is provided.
