| 1 | A novel conflict-free parallel memory access scheme for FFT constant geometry architectures显示文摘In this paper,a parallel conflict-free access scheme for a constant geometry architecture which is unlike the previous schemes is proposed.The proposed method only uses one modular addition operation,and does not involve complicated operations,thus reducing the hardware complexity of address generation.Because of the reduction of the combinational logic which is used to generate the access address,the scheme also reduces the time delay and accordingly improves the executable frequency of fast Fourier transform(FFT) processors.In the scheme,we use an arbitrary radix,i.e.,radix-r,to implement the scheme.The scheme is not only applicable to radix-r FFT processors with one butterfly unit,but is also suitable for FFT processors with multiple butterfly units.Because the same architecture is used for every stage of the constant geometry,it can enhance the flexibility of the FFT implementation.Finally,we analyze the resource costs and time delay of the proposed method,and the results verify the advantages of the proposed scheme. | MA CuiMei CHEN He YU JiYang LONG Teng | 2013 | Science China(Information Sciences)2013，56，4： | 5 |

| 9 | Investigation and mitigation of Mott neuronal oscillation fluctuation in spiking neural network显示文摘Mott devices,featuring low hardware cost and high energy efficiency,have been demonstrated as a key oscillatory element in artificial neurons to enable spiking neural networks(SNNs)such as conversionbased SNNs(CSNNs).However,there will be inevitably non-ideal fluctuation in the oscillation behavior,causing the accuracy degradation of networks.In this paper,we investigate the Mott neuronal oscillation fluctuation(NOF)through experiments and modeling.The results show that the NOF phenomenon conforms to Gaussian distribution and originates from thermal fluctuation induced switching voltage variations.We construct a two-layer CSNN for image recognition tasks to study the NOF effect and propose the activation function boundary(AFB)method to strengthen the stability of the network.The results indicate that AFB can improve the accuracy of CSNN by up to 15.5%by tightening output distribution. | Lindong WU Zongwei WANG Lin BAO Linbo SHAN Zhizhen YU Yunfan YANG Shuangjie ZHANG Guandong BAI Cuimei WANG John ROBERTSON Yuan WANG Yimao CAI Ru HUANG | 2024 | Science China(Information Sciences)2024，67，2： | 0 |
