AbstractThis paper presents a framework based on embedded SOC systems, which allows the testing and use of control algorithms implemented on FPGA circuits. For monitoring and parameterization a real-time Linux operating system was used. In this paper different methods for data exchange between the operating system and the control unit were introduced. The delay between the operating system and the control unit during the data exchange was studied and the measurement results discussed reflect the real-time functionality of the system.

Location Interaction

In order to make up for the deficiency of the lack of the location interaction between users of most LBS based applications in the market, a multi-user location sharing method(MULS) is proposed. Starting from the applications such as ordering food in different places and collective travel, it shows that this method can provide the location interaction between users and improve the location service function of the application. Secondly, the feasibility of the method is illustrated by introducing the principle of MULS. Finally, on the IOS operating system, this method is gradually implemented from several aspects of location acquisition, sharing strategy, data exchange, and overall framework. Conclusions: The MULS method can be implemented on the basis of existing applications. This method can effectively provide the location sharing among users, so that it is possible to achieve the query and positioning of the real-time location of multiple people among team users, team collection progress, the location of non returned team members, so as to let LBS application bring greater convenience to people’s life.

The purpose of the mixed-mode system research is to handle devices with the accuracy of real-time systems and at the same time, having all the benefits and facilities of a matured Graphic User Interface (GUI) operating system which is typically nonreal-time. This mixed-mode operating system comprising of a real-time portion and a non-real-time portion was studied and implemented to identify the feasibilities and performances in practical applications (in the context of scheduled the real-time events). In this research an i8751 microcontroller-based hardware was used to measure the performance of the system in real-time-only as well as non-real-time-only configurations. The real-time portion is an 486DX-40 IBM PC system running under DOS-based realtime kernel and the non-real-time portion is a Pentium III based system running under Windows NT. It was found that mixed-mode systems performed as good as a typical realtime system and in fact, gave many additional benefits such as simplified/modular programming and load tolerance.
