Multi-core processors are widely used in IoT devices because they provide more powerful computing capability while ensuring low power consumption. Therefore, it requires the operating system on IoT devices to support and optimize the scheduling algorithm for multi-core processors. Nowadays, microkernel-based operating systems, such as QNX Neutrino RTOS and HUAWEI Harmony OS, are widely used in IoT devices because of their real-time and security feature. However, research on multi-core scheduling for microkernel operating systems is relatively limited, especially for load balancing mechanisms. Related research is still mainly focused on the traditional monolithic operating systems, such as Linux. Therefore, this paper proposes a low-latency, high- performance, and high real-time centralized global dynamic multi-core load balancing method for the microkernel operating system. It has been implemented and tested on our own microkernel operating system named Mginkgo. The test results show that when there is load imbalance in the system, load balancing can be performed automatically so that all processors in the system can try to achieve the maximum throughput and resource utilization. And the latency brought by load balancing to the system is very low, about 4882 cycles (about 6.164us) triggered by new task creation and about 6596 cycles (about 8.328us) triggered by timing. In addition, we also tested the improvement of system throughput and CPU utilization. The results show that load balancing can improve the CPU utilization by 20% under the preset case, while the CPU utilization occupied by load balancing is negligibly low, about 0.0082%.","PeriodicalId":211012,"journal":{"name":"2021 7th International Symposium on System and Software Reliability (ISSSR)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132889732","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 language text information, there are many pronouns and polysemous words, which makes the problem of polysemous words appear in the text preprocessing stage. Based on this problem, this paper adopts a Chinese named entity recognition method based on the BERT-Transformer-BiLSTM-CRF model. First, use the pre-trained BERT model in a large-scale corpus to dynamically generate a sequence of word vectors according to its input context, then use the Transformer encoder to model the contextual long-distance semantic features of the text, and use the BiLSTM model to perform sentence context features Extract, and finally input the feature vector sequence into CRF (Conditional Random Field) to get the final prediction result. Tested on the public MSRA Chinese corpus.

However, because traversal algorithms of the graph are not designed for test generation, some inexecutable test paths are usually generated from the graphical model of the system when the system has complex software behaviors. This problem will not only lead to the failure of software testing, but also greatly increase test cost of software. The paper discusses the problem of inexecutable test paths in model-based testing. Then, an improved algorithm is intended to generate a test tree from the graphical model so that test paths generated from the test tree satisfy transition constraints in the model. Next, we conduct an experiment on four systems to analyze the problem of inexecutable test paths. Experimental result shows that 1) our algorithm is more efficient than two traditional algorithms for constructing the test tree of the system, and 2) there are still some challenges that need to be overcome in order to obtain more reliable test cases in test generation from graphs.","PeriodicalId":211012,"journal":{"name":"2021 7th International Symposium on System and Software Reliability (ISSSR)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121952009","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, the car having only ABS is not enough. For example, the distribution of braking force in the early stage of the car braking, and the car in the wet road starting acceleration. In the situation, the car requires ABS and other control systems of the car work together. In this paper, the electronic braking force distribution device (EBD) is integrated into the ABS to form the ABS/EBD braking system based on CAN bus. It consists of speed sensor, CAN bus, control unit and braking force distribution device. The system is used to improve the directional stability of braking before the ABS system starts. By measuring the slip rate of four wheels, the degree of locking is judged, so that the slip rate of four wheels is close, so that all wheels can be locked at the same time as much as possible. Compared with other braking force distribution systems, the system is characterized by the use of CAN bus as the carrier, which effectively improves the system's response ability and computing ability. It is also convenient to combine with other electronic systems on the car to form the intelligent network of the car.","PeriodicalId":211012,"journal":{"name":"2021 7th International Symposium on System and Software Reliability (ISSSR)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115221589","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}
