The iterative property of inverse butterfly permutation network makes it possible to implement shift operation with simple routing algorithm, which has high application value in cryptography, digital image processing and other fields. Based on the inverse butterfly network, this paper proposes a subword shift unit, which integrates the operations of subword rotation shift, subword logical shift and...
Gas insulation equipment are widely used in high voltage electrical field, which use SF6 gas as insulation medium and have many advantages such as low maintenance and high reliability. But SF6 leakage caused by factors such as manufacturing, installation and material aging will severely reduce the insulation performance of equipment and eventually lead to the occurrence of insulation fault. Therefore,...
The CORDIC algorithm is the most important algorithm to achieve sine-cosine signal. This paper discussed the architecture of FPGA implementation, optimization measures were proposed according to hardwarere sources, angular coverage and computing precision of the algorithm. There are 3 main problems for hardware implementation of CORDIC algorithm, based on the basic principle of the algorithm. Combined...
In this article, a method of image registration based on feature space of distance (FSD) between points is firstly introduced into dim and small target detection in deep space background. This algorithm uses the feature space to calculate the transform parameters and realizes the dim and small target detection through the suppression of the star background. The experimental results indicate that our...
Different doctor may give different diagnosis descriptions on the same result in the medical management system, some even not standardized and lots of the diagnosis are same, doctorpsilas repeated input is inefficiency and can not solve the customerpsilas queuing problem. The traditional K-nearest neighbor algorithm has the drawback of slow recommend while the sample space is large. This paper adopt...
