This paper introduces the design of the lab intelligent remote monitoring system based on S3C2440 ARM microprocessor. Aiming at the issue that document storage brings many troubles to the embedded developments and the traditional databases can not be used in the embedded application development, it focuses on the embedded database storage with SQLite as the core and studies the feasibility in the...
Describe a software and hardware design solution of an embedded web-based remote monitoring system for the environment in the laboratories. Build an embedded web server to publish the data of sensor networks and video images to achieve remote monitoring which is based on B / S architecture. Managers can control the equipments in the lab through a web browser which is cross-platform. The embedded database...
The Lab Intelligent Monitoring System based on S3C2440 ARM microprocessor and embedded Linux has been designed to accomplish the remote monitoring of the parameters and video images of environment in the Laboratory. The embedded database SQLite manages the data collected by sensor networks. A system program based on Qt/Embedded and Linux drivers realizes the local management of environmental data...
This paper probes into the design of the intelligent monitoring system based on S3C2440 ARM microprocessor. It focuses on the difficult points of developing the GUI applications based on Qt/Embedded and the Linux drivers for various types of sensors in the Lab Intelligent Monitoring System project, achieving the combination of Qt/Embedded and the linux system programming.
Dynamic voltage scaling (DVS) is an effective technique to reduce the energy consumption of CMOS powered embedded systems through software control. However, applying fixed priority DVS algorithms introduces increased number of preemptions, which, in turn results in extra time delay and energy cost. Effectively reducing the number of preemptions is therefore required. In this paper, we propose to integrate...
Along with the prevailing of mobile devices, the demand for efficient power consumption has become one of the major issues in designing embedded system. Dynamic voltage scaling (DVS) is a technique that can reduce energy consumption by changing the processor voltage levels dynamically. Fixed priority with preemption threshold (FPPT) scheduling is a scheduling policy that includes preemptive and non-preemptive...
In this paper, our work is to frame multi-core processors systems which complete parsing PDF, and in order to parse quickly, we also design hardware accelerator for the graphics rendering engine which are time-consuming most. The final implementation of the system has been tested using a Xilinx University Program Virtex-II Pro Development Board, which features a Virtex-II Pro XC2VP30 Speed Grade -7...
