DESIGN OF A HIGH-PERFORMANCE 32-BIT ALU WITH OPTIMIZED ARITHMETIC UNITS FOR LOW-POWER VLSI SYSTEMS
The basic computational unit of high performance processors and digital signal processor systems is the Arithmetic Logic Unit (ALUs). For implementing high speed and low power VLSI system, fast arithmetic circuits with higher performance and less resources are required. The design and implementation of high speed 32-bit ALU based on Han-Carlson parallel prefix adder and Radix-4 Booth encoded Dadda multiplier is discussed in this paper. The designed ALU is a combination of fast arithmetic computation block and optimized logic control circuits in an effort to reduce the propagation delay and power consumption. It is a fast propagation characteristic combination of Kogge-Stone and Brent-Kung adder using Han-Carlson adder. For better efficiency and less delay Radix-4 Booth encoded Dadda multiplier is proposed which reduces the number of partial products to the minimum with the help of Booth radix-4 multiplication and less multiplier delay. The whole ALU is designed, synthesized in Verilog HDL and FPGA design flow, and CMOS design flow. Results illustrates that designed ALU provides a critical delay of 2.65 ns, power consumption of 14.8 m W and PDP of 39.22p J, which makes it better than the existing ALU designs.
