    Is it more efficient to multiply in BCD ( BCD x BCD = BCD ) or to Multiply in BCD to get a binary result, and then convert it ( BCD x BCD = Binary -> BCD) to BCD? .. Another thing is that a Binary multiplier is way easier to make. The 8 equations that I have for a #x# BCD multiplier are ugly.. And I'd have to add more results. I'm not sure which I want to use. If you need any further explanation, please ask.

    Thanks! :)

    P.S. By efficient, I mean speed. I'm not worried about size, yet.

    Are we talking hardware or software?
