Abstract: A floating point unit (FPU) is described which processes normalized binary numbers. All multiply, add, and subtract calculations are performed using the format (A*B)+C or (A*B)-C. The operation A*B is performed in parallel with the alignment of C to the product of A*B. An output of the multiplier and the aligned operand C are applied to a carry save adder, whose output is then applied to a carry propagate adder to generate the result A*B.+-.C. The output of the carry save adder is also applied to a combined leading one anticipator (LOA) and leading zero anticipator (LZA). The output of the carry propogate adder is provided to a post normalizer. The output of the combined LOA/LZA is applied to the input of a multiplexer, with the control input of the multiplexer being connected to the most significant bit of the adder output, where this most significant bit indicates whether the result is positive or negative.

Abstract: An adder circuit includes various methods to control the carry bit at data boundaries when attempting to process multiple data of multiple types. One method is to generate both propagate and generate signals from the input data and modified propagate and generate signals from the data boundaries, which can then be used in a conventional carry-lookahead adder to produce a resulting sum that is correct regardless of the data type being processed. Another method is to insert special carry blocking, propagating or generating cells at the data boundaries of the input data. These cells are then filled with the appropriate blocking, propagating or generating signals, either by table look-up or circuit implementation using data type and processing type inputs. This data stream can then be added with a conventional adder. However, if the special cell replaces data at the boundaries, another adder can be used to process this boundary data separately prior to inserting the special cell.
