Multi Operand Decimal Adders: a mixed Binary - BCD approach
Spread-sheet Design Tools for:
_______________________________________________________________________________
a) - BCD digits parallel Adder
Digit Adders
DigitAddF.xsl
The spreadsheet uses only FullAdders in the Compression stages
BCD digits adders with least significant single bits
Digits Adders with least sign. 1's
DigitAddH.xsl
The two above spreadsheets hold for:
N <610; (except N = 453 ; 471 to 480 ; 489 to 492;506 to 518 ;
523 to 526 ; 541 to 596; )

Design of Binary-to-Decimal Converters
The basic operatio in the binary to decimal conversion:
Dividing a binary number by ten

For the design of minimal BD converters, through simulation
N <712;
Collection of BD Converters.
Any Converter labeled N is valid (minimal) for any N in a range including all (if any) values larger than the N of the preceding scheme to the N of the given scheme.
