  • Apparatus and method for expediting subtraction procedures in a carry/save adder multiplication unit
    Patent number: 4862405
    Abstract: In a multiplier unit implemented with carry/save adder stages and executing a modified Booth algorithm, the signals, required to complete the 2's complement in order to perform a subtraction operation during the multiplication procedure using carry/save adder cells, are entered in the first carry/save stage in the appropriate carry/save cell positions. In this manner, one less signal is processed by the time-critical least significant cell associated with each carry/save adder stage, thereby reducing the overall time delay associated with the multiplier unit and accelerating the multiplication operation.
