Recently, speeding up real time calculation using the specialized hardware accelerator is often used in the various engineering and science area, and the accelerators are required to include PCI express interconnection between FPGA and a host computer. The implementation of the high speed PCIe for the multi-giga bytes per second transmission is one of the most difficult issue in the development of the accelerators. There are several commercialized IP solutions and research results in the literature, but these solutions are required extra cost and design period to analyze the detailed implementation method. For the hardware accelerator on Xilinx FPGA, utilizing Xilinx's XDMA PCIe IP, which is provided without extra charge, can be the best solution in terms of the development period and cost. Consequently, this paper presents the evaluation system on Zynq-7000 FPGA and Windows 10 host computer, and analyze the performance of the PCIe IP with various configuration parameters.

Since China and South Korea are equally concerned about high school education, so this study focuses on high school education, through the study of the objectives and structure, content, implementation, and evaluation of China's general high school education curriculum reform program, analyzing its characteristics and problems, and based on the problem, point to make the corresponding suggestions and comments. The results of the study, first, the reason for the reform of the high school curriculum is because of the emergence of compulsory education and need a curriculum that fits the actual high school education. Second, the character of China's high school curriculum goals are based on the trend of China's future social development, focusing on students' lifelong learning ability and core competence. the character of structure is that the subject courses and activity courses are parallel, and the elective courses and compulsory courses are parallel. The character of content is the emphasis on the era, basicity, and selectivity of the content. the character of Implementation and evaluation is the provision of support for implementation and the adoption of sustainable development methods. High school education courses have three problems in the curriculum itself and teachers and university entrance exams. There three suggestions about the problems, first, it is necessary to examine whether high school education is for preparation for admission or education for the public. Second, it is necessary to provide training that can enhance the core competencies of teachers. Third, the high school graduation evaluation and the university entrance evaluation system need to be improved.

Today, most education activities in the junior or senior schools are connected with evaluation. In fact, the evaluation to be accomplished is not the practice of college or university entrance examination but the evaluation analysis of studies accomplishment. In this program, students process their teaming contents according to their level, and they evaluate the accomplishment of learning by themselves. Through the various analysis of evaluation, students who are not in the appropriate level get into the learning plan of low level course. This study makes them notice the lack of teaming ability in time and proposes proper evaluation system which offers right feedbacks and various analysis information for themselves.

Purpose: Accurate monitoring of information from various agricultural vehicles is one of the most important factors for appropriate management strategy of field operations. While there has been a number of study and design on applications of sensors and actuators for data acquisition and control system in tractor, incompatibility between various customized hardware and software has become a major obstacle to the universal deployment in real field operation. International standard for implementation of electronic control unit (ECU) in agricultural vehicles has becoming a mandatory requirement for inter-operation compatibility in the international trade of agricultural vehicle industries. The ISO 11783 standard is basically based upon well known communication technology designated using the controller area network (CAN) bus. While CAN bus could provide 1.0 Mbps of communication speed, the standard only recommended 250 kbps. Methods: This study presents the implementation and evaluation of ISO 11783 for tractor electronic control units (TECU)with a higher transmission rate from multiple ECU than 250 kbps. Throughput and loss rate of the developed prototype were calculated across manipulated bus load for laboratory experimental tests, and the maximum requirement of transmission rate by ISO 11873 was satisfied with lower than 60% of bus load. Results: Field tests with a TECU implemented to process messages from global positioning system (GPS) receiver resulted that the root mean square error of position information was lower than 4 m with 0.5 m/s as a travelling speed. Conclusions: Results of this study represent the utilization of the international standard ISO 11783 to providepractical developments in terms with the inter-operability of TECU.

In this paper, we propose a high level design architecture of WCDMA(UMTS) base station modem and synchronization algorithms applied to the proposed architecture. Also analysis of each synchronization algorithm and performance evaluation of fixed point designed modem are shown. Since the target system is base station modem, each synchronization algorithm is designed for its stable operation. To minimize implementation complexity, optimum fixed point design for best operation of synchronization algorithms is performed. We performed symbol level link simulation with fixed point designed modem simulator for data rate of 12.2kbps, 64kbps, 144kbps, and 384kbps. We compared performance results to the minimum requirements specified in 3GPP TS 25.104(Release 5). Extensive computer simulation shows that the proposed modem architecture has stable operation and outperform the minimum requirement by 2 dB. The proposed modem architecture has been applied in the implementation of WCDMA reverse link receiver modem chip successfully.
