This paper addresses the problem of task allocation in real-time distributed systems with the goal of maximizing the system reliability, it has been shown to be NP-hard. Many studies have been made to solve this problem without considering the real-time constraint. We first take account of the deadline constraint in order to formulate this problem, and then(More)
On the hardware platform of Distributed Real-Time Simulation, a communication module based on reflective memory network was realized in FPGA. As an infrastructure module, it could be integrated with other modules seamlessly. Under the speed-first rules, DMA engine in PCI Master mode was designed, and 64bits/32bits bus compatibility was realized. In order to(More)
The Operating System scheduler is designed to allocate the CPU resources appropriately to all processes. The Linux Completely Fair Scheduler (CFS) design ensures fairness among tasks using the thread fair scheduling algorithm. This algorithm ensures allocation of resources based on the number of threads in the system and not within executing programs.(More)
To improve the real-time property for typical Pulse Doppler radar simulation, an idea of signal-level simulation using hardware was proposed. The system framework and information flow was studied, then a host method of moving target echo simulation was given. Most of all, radar signal processing was realized by FPGA, which includes digital quadrature(More)
—Triangulated irregular network is a frequently-used digital terrain model which is used to fit the continuous distribution phenomenon, it could reduces the data redundancy when the terrain is comparative flat and could commendably reserves the elevation characters of terrain character point. Based on the above-mentioned characters, this paper analyzes and(More)
