In this paper, we propose an equivalence checking tool for verification of the source and target programs; Finite State Machines with Datapath (FSMD) is used to model the original and the transformed programs. The tool is based on a deep state sequence (DSS) strategy proposed in our previews work. The false computation problem of value propagation (VP) based method can be solved by our tool.

With the addition of a new generation of process design, the research of BTI has become the most critical mechanism. This paper mainly discusses the important breakthrough obtained by establishing aging model and standard logic unit after accurate estimation and comprehensive analysis. A typical example in this paper is using LTSPICE software to simulate and design in 32 nm CMOS process. Through the simulation results, it can be concluded that the transmission delay of Schmitt flip-flops which is input buffer in this design is significantly improved. Although affected by BTI aging, the transmission delay of 11 cascaded CMOS inverters is increased by about 30% and the delay is reduced by above half compared to before. The need of increasing reliability is optimized by combining with ALI and AHI technology, which reduces the transmission delay by about 35%.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121438678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the utilization rate and deployment rationality of barrier-free service resources and enhance the capability of guaranteeing barrier-free service in civil aviation airport, we need to provide decision support for the deployment of barrier-free service resources in the terminal building. This paper uses a clustering algorithm to obtain the cluster centers of passenger's demands, calculates the deployment range of resources in the cluster centers by using the geometric center method, combines passengers’ intentions to explore the types of service resources, targets the usage frequency of each resource and the available number of people that can be served at a time, so as to generate optimized suggestions for the deployment of resources. This paper simulates passengers’ demands and moving trajectory in the experiment and verifies the feasibility of applying Python tool into the deployment of barrier-free service resources.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132214955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to provide better services for passengers in civil aviation, we aim at the common problems of passengers in the airport environment, simulate the possible service demands of passengers, analyze the key feature data in the demands, and combine the joint identification model of DIET to realize the accurate understanding of the intention in the natural language of passengers.

Yet, evaluation of failure probability via direct sampling from a given system can be computationally expensive and sometimes impossible. Although the construction of a response surface/surrogate could reduce such computational cost, reliance on its sampling alone may still yield an erroneous estimate of the failure probability. In this paper, we employ generalized polynomial chaos and develop an adaptive method whose surrogate model evolves with the additional data sampled from the underlying system as the iteration proceeds. It is more flexible by not requiring an accurate surrogate model in priori. Via three distinct numerical examples and one practical problem on a spintronic device, we demonstrate that our novel scheme provides an efficient tool to estimate system failure probability.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123957446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Edge computing center began to accelerate its distributed trading business based on FPGA technology, especially in the field of securities. Shanghai stock market uses efficient FIX Adapted for Streaming (FAST) protocol to transmit the market data. FAST protocol has high compression ratio and complex decoding process. Aiming at efficient FAST protocol decoding, we propose a new general FPGA logic design framework, which implements a low complexity parallel FAST field matching state machine and a low latency stock code mapping mechanism. In this paper, Vivado HLS is used to design and generate the relevant codes. Test results show that the clock frequency after place and routing can reach 250MHz under Xilinx VU37P FPGA. For the 10-level and 50-order message of FAST decoding, the processing delay of core parsing module is only 36ns and 56ns, FPGA subsystem delay is about 120ns.
