A Modified 2:1 Multiplexer-Based Low Power Ternary ALU for IoT Applications

The ternary logic has a benefit over the binary logic which provides a secured solution to achieve a trade-off between the area and power of the design.However, from the structure of the ternary Aritmetic Logic Unit (ALU), it is clear that its architecture increases the area, propagation delay, and power consumption.To overcome this drawback, a loopback algorithm is proposed to achieve low power and high throughput Internet of Things (IoT) processors.The loopback algorithm reduces the number of processing stages in multipliers and adders which can significantly reduce area and power dissipation.The proposed 2:1 multiplexer-based approach reduces the need for a decoder and results in low power consumption.The proposed design will be implemented in Xilinx ISE 13.0 and simulation will be done in Modelsim.The modified Ternary ALU (TALU) performs finer than the previous TALU method.The number of registers used in this architecture is reduced by up to 25% than the existing system therefore there is a reduction in power dissipation.
