- Hi!
-
- While working on a research on the usability of redundant arithmetic in general
- purpose processors I stumbled upon a few problems. Maybe they aren't very big,
- but I can't find the answer nonetheless. I'd like to ask the people on this
- newsgroup for a solution.
-
- It is all about carry sum redundancy. I know how it works, but in none of the
- articles was something about the representation of negative numbers using carry
- sum redundancy. Could somebody please tell me how one represents negative numbers
- in carry sum redundancy?
-
- The other problem I had was with the difference between carry sum redundancy and
- signed digit redundancy. I mean, is there a difference in usage of hardware, speed
- or complexity of the circuits needed?
-
- Any help is much appreciated.
-
- Greetings,
-
- Maarten Hofman.
