Design and Power Optimization of a 64-Bit SIMD Processor with Efficient Carry-Bit Handling

In the rapidly evolving field of digital processing, the demand for high-performance yet energy-efficient computing systems is ever-increasing. The paper focuses on the design and implementation of a 64-bit Single Instruction, Multiple Data (SIMD) processor capable of operating in four distinct modes: 8x8 bits, 4x16 bits, 2x32 bits, and 1x64 bits. The processor is developed using Verilog hardware description language, enabling flexibility and scalability in various applications. To further enhance the processor's efficiency, a novel low-power SIMD architecture is proposed, with an emphasis on optimized carry-bit handling. This architecture aims to reduce power consumption without compromising processing speed or functionality. A comprehensive power analysis is conducted to compare the energy efficiency of the standard SIMD design with the proposed low-power variant. The results demonstrate the effectiveness of the carry-bit optimization in reducing power usage, contributing to the solution for high-performance computing.
