Abstract: is stored and used in the subsequent bit time. The most compact combinatorial (parallel) adder, subtracter, or accumulator consists of cascaded CLBs. Each CLB implements a full adder, accepting one bit of , unit, Figure 2, comprises a 1-bit full adder/ subtracter and a carry/borrow flip-flop, and can be , by J. Sklansky. Using this algorithm, a 16-bit adder requires 41 CLBs, but settles in only three CLB , Operand ADD/SUB RESET X3119 X3119 Figure 1.
