The architecture and performance of a 20-bit arithmetic processor based on the logarithmic number system (LNS) is described. The processor performed LNS multiplication and division rapidly and with a low hardware complexity. Addition and subtraction in the LNS require the support of a table lookup unit. A scheme is proposed to minimize this complexity using a partitioned memory (ROM) and a PLA
