Abstract
In this paper we present the design of ALU based on Redundant Binary Signed Digit (RBSD). The unique feature of RBSD allows addition
without typical carry. RBSD along with unsigned number is proposed in my designed. A redundant binary representation is a numeral system that uses more bits than needed to represent a single binary digit because of which most numbers have several representations. ALU is designed using VHDL and its RTL view is generated by its FPGA implementation.
