Summary:
The design performs addition and subtraction on 64-bit operands in a single path
adder with exception and rounding handling fulfilling the final version of the
IEEE Standard for Floating-Point Arithmetic P754 which was published in
August 2008. We introduced two different implementations for the BCD-adder,
BCD-subtractor internal design as well as different architecture. Complete test
and verification is performed on all the design versions fulfilling 3063 test vectors
supplied by IBM Corp. and supporting 2 extra rounding modes proposed by
IBM.
