Abstract

A two-cycle decimal data path,which contains the true, complement, double and quintuple functions along with an adder, is checked by a parallel residue data path whose output is compared to the residue generated from the output of the decimal adder. This residue data path is also a two-cycle path. The figures show the interface between the decimal data path and the residue data path.
