Abstract :
Parallel addition and subtraction of two numbers with signed-digit number representation can be performed in constant time. A signed-digit representation for radix r=10 (SD10R) is presented, and the usefulness of asymmetrical SD10R is considered. The authors propose p(qk. . .q1)-valued SD10Rs in which p is represented as a combination of qk to q1. They also describe a p(q2q1)-valued SD10R addition and subtraction unit in which p is large. Simulation data for typical SD10Rs are compared
