Aiming at the complexity and difficulty of millimeter wave radar target detection algorithm, SYS/BIOS is used to design and implement the algorithm. Due to the large amount of computation and tasks, the algorithm of millimeter wave radar target detection is implemented by SYS/BIOS embeddedoperatingsystem, rather than developing based on bare computer. The operatingsystem is modular, so it is convenient to manage and develop programs, and effectively solves the difficult problem of millimeter wave radar target detection algorithm. The feasibility of the algorithm is proved by practical experiment.

The traditional distributed operatingsystem (OS) and homogeneous multiprocessors OS are not suitable for heterogeneous multi-core processor (HMP) in real-time and efficiency performance. After researching the structure and the development trend of the HMP, this paper presents a multi-master model real-timeoperatingsystem architecture for HMP, which is designed with symmetric structure and functional modularization, and every kernel can manage resources, tasks and other shared devices as a master to improve the real-time and efficiency performance, to solve the bottle-neck problem that the single master can not satisfy the requirement of performance with increasing of the slave number. This architecture can adapt to different structure processor core with configurable function module. On the other hand, it can also reduce the development difficulty of the heterogeneous multi-core processor OS.

The rate-monotonic (RM) algorithm is a classic fixed priority real-time scheduling ***, in most embeddedreal-timesystems where the workload is composed of many tasks of high frequency and short execution time, the overheads from preemptions of the real-timeoperatingsystem will lead to a low resource utilization rate if the RM algorithm is directly used. By studying the preemption relationship of the tasks scheduled by RM algorithm, a model of preemption overheads is established with task attributes, based on which the run-time preemption overheads of RM algorithm are reduced by optimizing the start time of the tasks in embeddedreal-timesystems. Finally, the experimental results show the validity of the proposed strategy.

This paper proposes mu T-Kernel, a real-timeoperatingsystem for networked tiny devices, which adopts a preemptive priority-based scheduling. It provides a sophisticated application programming interface to facilitate software development. In addition, to provide rich functionalities with a small-footprint, the kernel is reconfigurable with respect to the API. Moreover, mu T-ernel supports a power management which utilizes the periodicity of WSN applications. We conducted performance analyses of the memory footprint and energy consumption, and migrated sample applications to show the programmability of mu T-Kernel. Our results show mu T-Kernel is effective for developing WSN systems while realizing a kernel small enough to fit into a resource-constrained node.

A power load management system based on ARM-7 microcontroller and GPRS is presented in this paper. The proposed system consists of electronic KWH meter, intelligent management terminal (IMT) and management centre. The intelligent terminal is sued to acquire information from KWH meter, control the energy-consuming device and communicate with management centre via GPRS network. How to implement the IMT by using ARM-7 microcontroller and GPRS telecommunication module is discussed in detail. Also the software design of the terminal with high performance embedded real-time operating system mu C/OS-II is presented in this paper.
