Abstract
A special functions arithmetic logic unit (ALU) method and apparatus includes an ALU register, an ALU register value processor coupled to the ALU register for receiving and processing ALU register values to produce output data, and a normalizer. The normalizer receives and processes complex memory values to produce normalized output data independently of the output data from the ALU register value processor. The ALU register value processor includes a parser, combiner, polynomial divider, magnitude estimator, and a Hamming distance determiner. The normalizer includes an exponent determiner and first and second scalers for producing normalized X and Y data of the normalized output data.
