Nonlinear function approximation has been studied for decades. With the rise of transformer-based AI models, the need for efficient, low-complexity circuit implementations for functions like softmax, GELU, and layer normalization has intensified due to non-negligible hardware overhead. Existing methods reuse softmax hardware for GELU or reconfigure both, but the preprocessing required for their GELU approximation results in area inefficiency. To address this, we propose a novel successive approximation technique that reduces preprocessing complexity and compensates for errors in successive steps. Additionally, our reconfigurable design supports softmax, GELU, and square root functions, optimizing hardware area and flexibility. Experimental results show a 2.48x increase in throughput per area for softmax and a 4.96x increase for GELU, with only a 0.09% accuracy loss under BERT-base models in comparison to related work.
Recently, cloud computing has been recognized as an effective paradigm for offering an on-demand platform, software services, and an efficient infrastructure to cloud clients. Due to the exponential growth of cloud ta...

To realize the economic optimization dispatch of PSMG (Photovoltaic Storage Micro-grid), considering the stochastic influence of multiple uncertainties, this study formulates a day-ahead optimal dispatching strategy of PSMG with the minimum comprehensive operating cost as the objective function. Firstly, the source-load uncertainty is dealt with by scenario generation using the Monte Carlo method and k-means clustering algorithm. Then the peak shaving ability of the system is enhanced by the introduction of flexible loads, and the scheduling flexibility of the photovoltaic storage system is increased by the integrated demand response increases the scheduling flexibility of the photovoltaic storage system. Finally, simulation results show that the scheduling scheme can prompt the source-load to participate in peak shaving and valley filling at the same time, increase the new energy consumption capacity of the photovoltaic storage micro-grid, and effectively improve the economic and social benefits of the micro-grid.
