Abstract:
Modern CMOS processors face a significant challenge in power consumption, primarily due to switching and leakage power. With rising demands for energy-efficient systems, especially in mobile and IoT devices, managing dynamic and static power has become essential. Conventional clock gating techniques lack adaptability to workload variability, leading to inefficient power savings. Fixed gating schemes either over-constrain performance or underperform in power savings. This work proposes a Low-Power Reconfigurable Match Table (RMT)- based Clock Controller that dynamically adjusts clock gating gra

Abstract:
In this paper, a new low power design method of the FIR filter for image processing is proposed. Because the correlation between adjacent pixels is very high in image data, the clock gating technique can be a good candidate for low power strategy. However, the conventional clock gating strategy that is applied independently to every flip-flop of the filter give rise to too much additional area overhead and couldn't get a good result in the power reduction. In our method, each tap register, which is used to delay the input data in the filter, is partitioned into two sub-registers according to t

Abstract: In digital signal processing and arithmetic circuits, Booth multipliers are widely used for efficient multiplication of signed numbers. However, conventional Booth multipliers consume significant power due to their full precision operation.
