Since bitstreams stored in external memory are vulnerable to malicious attacks, most FPGA manufacturers provide bitstream encryption. In this paper, the structural differences between an unencrypted bitstream and an encrypted bitstream for Xilinx's FPGA series are investigated. First, the encryption algorithms used for each series are described, followed by the procedure for generating an encrypted bitstream using Xilinx ISE and Vivado. Lastly, the difference between the unencrypted and encrypted bitstreams for Xilinx FPGAs before 7-Series, 7-Series and after 7-Series is compared. Using the analysis, we demonstrated that it can be possible to verify if encryption is applied or not in real world utilizing encryption information extracted from the bitstream during its transfer from external memory to FPGA.","PeriodicalId":373752,"journal":{"name":"2023 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133233091","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 general, the operating characteristics of these DC motors determined through proportional-integral-differential (PID) control in the microcontroller. However, in a previously designed PID controller, once the PID coefficients are determined, it is difficult to change their values. In this paper, a PID coefficient update technique was applied to a disturbance occurring in a DC motor at runtime to increase the response speed of the system and reduce the root mean square error. This technique can be applied to various industrial applications that require precise control even when there is a disturbance in the runtime.","PeriodicalId":373752,"journal":{"name":"2023 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133701049","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 the case of conventional LDO regulators, a method of adjusting the size of the external capacitor has been used to alleviate overshoot and undershoot phenomena. When the size of the external capacitor increases, the overshoot and undershoot voltages are reduced, but the chip size increases. Therefore, the proposed LDO regulator is designed to have improved overshoot and undershoot voltages using the current buffer structure instead of the method of resizing the external capacitor. The current buffer structure was designed so that it could detect the overshoot and undershoot voltages generated from the feedback voltage, and charge and discharge the current. As a result, it was verified that the LDO regulator with the current buffer structure could improve the overshoot and undershoot voltages according to the load current. The LDO regulator having the current buffer structure has a load current of up to 250 mA at the output voltage. According to the measurement results, when the load current is 250 mA, the power voltage according to the undershoot is 38 mV, and the power voltage according to the overshoot is 29 mV. Additionally, the LDO regulator with a current buffer structure has an ESD protection circuit built in to ensure reliability in ESD situations.","PeriodicalId":373752,"journal":{"name":"2023 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"33 7-8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131876314","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 this context, this paper proposes a person re-identification method that utilizes text guidance via the Contrastive Language-Image Pre-training (CLIP). To fully utilize CLIP, we show how to transfer their knowledge to person Re-ID network.

In the case of parking robots that directly lifts, the vehicle specifications must be measured because the fork to lift the vehicle must enter the lower part of the vehicle and be able to lift the vehicle. However, the cost-effectiveness is low even when an expensive sensor system is used due to the instrumentation environment. Therefore, this study proposes an inexpensive vehicle specification measurement system that combines ToF and ultrasonic sensors. Since the wheel outside is detected with a ToF sensor and the distance to the wheel outside is measured with an ultrasonic sensor, a basic experiment was conducted to check whether the wheel outside can be distinguished. The experiment replaced the wheels of the vehicle with a hexahedral box and aims to distinguish the corners of the box. As a result of the experiment, the measurement value of the area around the corner varies depending on the angle that was twisted, and the corners of the box could be distinguished.","PeriodicalId":373752,"journal":{"name":"2023 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129815410","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}

However, different imaging protocols even for the same disease such as posteroanterior (PA) and anteroposterior (AP) CXR often lead to domain gap, causing significant performance degradation and requiring more images with painstaking labeling. We propose a novel domain adaptation scheme via deep neural converter (DNC) in the scenario of having labeled PA and unlabeled AP; converting labeled PA into AP with label recycling and pseudo-labeling unlabeled AP. To overcome no labeled AP data, our proposed method exploits DNC to convert labeled PA CXR into AP CXR with label recycling as well as pseudo labeler for unlabeled AP CXR.","PeriodicalId":373752,"journal":{"name":"2023 International Conference on Electronics, Information, and Communication (ICEIC)","volume":"2013 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920265","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}

Many data augmentation methods have been studied to reduce overfitting and to improve the generalization ability of CNNs. One of the most widely used data augmentation techniques is Random Erasing which erases a random rectangle region of an image. Most of the augmentation methods are applied in the spatial domain, but augmentation techniques in the frequency domain are less studied. In this study, the image is processed with 2D discrete Fourier transform (DFT), and then Random Erasing is applied in the frequency domain. Finally, the inversed image generated with inverse DFT is used as an input.
