Residue Based Processing

What will residue based processing look like in the next 5 years?

Researchers at Digital System Research have discovered a new method for general purpose computation using residue numbers. While most digital hardware performs calculations using the binary number system, our system performs calculations using the residue number system. One key advantage of the residue number system is arithmetic operations do not require carry from one digit to another.

An innovative technique of our system is that it performs arithmetic operations in the residue number system in its entirety, that is, all calculations remain in residue number format until they complete. Once the result is ready, the result is converted to a binary value. This requires our system to multiply, divide, add, subtract, and compare integers and fractional values, entirely in residue number format. It also requires that conversion of integer and fractional values is convenient and fast.

Our system is the culmination of 20 years of research into residue number computing; DSR is excited to report the new processing paradigm helps broaden our understanding of arithmetic computation!
