Normalization unit for signed operands

A method for normalizing signed numbers comprising a plurality of residue digits having a whole range and a fractional range with a pipelined processor, the pipelined processor having at least one pipeline, the method comprising:

• receiving a non-normalized intermediate product at an input of the pipelined processor;
• converting the non-normalized intermediate product to a plurality of mixed-radix digits associated with a fractional range, producing one or more remaining residue digits associated with the whole range;
• storing the one or more remaining residue digits associated with the whole range in one or more pipelined registers, and producing a partial result comprising one or more whole digits;
• delaying the partial result to exit the at least one pipeline;
• reconverting one or more of the plurality of mixed radix digits associated with the fractional range to generate an uncorrected fractional result in a residue format;
• when the partial result is a negative value, generating one or more corrected fractional digits by summing a correction constant with the uncorrected fractional result;
• and
• concatenating the partial result and the one or more corrected fractional digits to generate a signed normalized product;
• wherein the partial result and the one or more corrected fractional digits exit the at least one pipeline as the signed normalized product.
