A Compact Dot Notation

Spread-sheet Design Tools based on Compact Dot Notation:

NOTE: input parameters in GREEN cells ; outputs in PINK cells

a) - Multi-Operand Parallel Adders

b) - Parallel Multipliers

Multipliers n<68
Mult64fa.xsl
for multipliers of up to 67 factors bits

Asymmetric Multipliers n<33
AsymMult32.xsl
for multipliers with factors of different lenghts, n and m
m <= n ; n + m < 33

The following SpreadSheet uses one HalfAdder per stage for obtaining
a number of single dots (least significant) and consequently a shorter final
parallel adder.
