Low-Power Priority-Based Arbiter for Optimal On-Chip Resource Allocation in SoC Architectures

Effective allocation of resources is an important necessity in today's digital systems, primarily in power-sensitive platforms like embedded systems, multi-core processors, and Network-on-Chip (NoC) interconnects. Standard arbiters, though popular, typically exhibit high dynamic power dissipation, latency, and biased resource allocation based on static priority policies [1]. This paper introduces Low-Power Priority-Based Arbiter design realized on FPGA platforms that incorporates energy-efficient mechanisms like clock gating, reduced signal transitions, and dynamic scheduling of priorities [2]. The design switches off unnecessary clocking during idle periods, adjusts the priority levels reactively to avoid starvations of requests that hold low ranks, and reduces unnecessary signal toggle rates to minimize switch transition power [3]. Experimental results thus obtained through Xilinx ISE prove that the Low-Power Priority-Based Arbiter realizes appreciable power reduction over state-of-the-art arbitration techniques, without trading off latency and fairness [4]. Comparative evaluation verifies improvement in power efficiency, throughput, and resource utilization [5]. The proposed solution is a scalable and reliable solution for modern-day digital architecture designs, opening up suitability for energy-sensitive application domains and paving the way for future works through adaptive workload modeling and machine learning–based arbitration policies [6].
