Abstract:
ALU is the cardinal functional unit in digital signal processor and embedded system devices which perform complex arithmetic and logical functions. In this paper we propose an ALU architecture (Vedic coprocessor) which is an integral unit of arithmetic and logical unit such as multiplication, division, square, cube, square root and cube root units. Each and every unit has an architecture based on unique Vedic math sutras. This proposed ALU architecture overcomes the existing drawbacks such as high delay, irregular structure of combinational circuits and high power dissipation. Vedic ALU is designed and simulated in XILINX ISE simulator and implemented using Spartan 3 FPGA. The proposed ALU is equivalent to Vedic coprocessor which increases the efficiency of multiprocessor configuration system design
