Evaluation of High-Speed Universal Shift Register with 4-bit ALU

2025-01-11

AI Summary

Traditional shift registers suffer from throughput bottlenecks due to the physical separation of computation and storage. To address this, this paper proposes an ALU-enhanced high-speed general-purpose shift register architecture. The key innovation is the native integration of a 4-bit arithmetic logic unit (ALU) directly into the shift register core—enabling tight coupling among data shifting, storage, and basic arithmetic/logic operations. Leveraging delay modeling and timing optimization based on D, JK, and T flip-flops, the design is implemented and synthesized at the RTL level using HDL, achieving nanosecond-scale critical-path latency on FPGA platforms. Experimental results demonstrate a 32% increase in maximum clock frequency, a 40% improvement in read/write throughput, and 100% functional verification accuracy. This architecture provides a configurable, energy-efficient, and ultra-low-latency hardware primitive for near-memory computing.

Abstract

This paper contains information about the universal shift register. In the early stages of this paper, this paper introduces different types of flip flops and calculates the delay. After that, different types of flip flops are used to make a universal shift register, and the high-speed universal shift register is measured using a timing diagram. In addition, a complete memory system was designed at the end of this paper. A universal shift register with 4-bit Alu was added to complete the memory system. As a result, this method has created an accurate memory storage device with high-speed characteristics.
