    • A combined adder and logic unit having a reduced operation delay of arithmetic and logic operations, and providing an improved fan in and reduced wiring delays and capacity if implemented in the arithmetic and logic section of a microprocessor chip. The unit comprises a carry network (30) connected to operand inputs for generating carry-out signals of the byte positions (By0-By7) and further comprises a pre-sum logic (32) having a bit function generator (42) and a sum generator (45, 46, 48). Said bit function generator derives from the operands Ai and Bi bit functions Gi, Pi which are provided as logic function output and as input to said sum generator for producing preliminary arithmetic functions (SUM0, SUM1) to anticipate carry-in signals of one or zero. A result selector (70) is controlled by a byte position carry-out signal (Cy55) from the carry network means and by operation control signals to select from the output of said pre-sum logic one of the arithmetic functions (SUM0, SUM1) or one of the logic functions as result of the unit operation.

    • A combined binary/decimal adder unit reduces the operation delay ine processing binary coded decimal operands and permit an increased cycle rate of a processor unit in which the combined binary/decimal adder unit is utilized. Pre-sums are generated for each decimal digit position in parallel to the generation and distribution of the carries over the total of decimal digit positions of the adder unit. The pre-sums anticipate the carry-in of the decimal positions and the need to perform six corrections after the carry-out signal of the highest decimal digit position has been generated. The carry-out signal of each decimal digit position is used in combination with operation control signals to select the correct pre-sum of the digit position.

    • A binary and decimal adder unit uses a pre-sum logic for generating pre-sums of the operands A, B under the presumption of one and zero carry inputs into the decimal digit position, and also uses a digits carry network for generating binary carries within the decimal digit positions and a high order carry out signal of said plurality of decimal digits. Each decimal digit position of said adder unit provides a six correction and a pre-sum selection. The pre-sum logic comprises a carry prediction logic for generating decimal digit position carry out signals on the presumption of a zero carry input and of a one carry input into the decimal digit. In response to gating signals derived from the carry out signals of the carry prediction logic and operation control signals a pre-selection is performed for selecting a qualified pre-sum generated on the presumption of a zero carry input into the decimal digit, and for selecting a qualified pre-sum generated on the presumption of a one carry input into the decimal digit. The pre-selection of the qualified pre-sums is performed for all decimal digit positions in parallel to the generation and distribution of the carries in the digits carry network over the total of decimal digit positions. The pre-sum selection logic further comprises a two way selector which is responsive to a digit carry-in signal from the digits carry network for selecting one the qualified pre-sums as the correct sum of the digit position. According to one embodiment of the invention, the pre-sum logic generates six corrected pre-sums which are included in the pre-selection of qualified pre-sums.
