In view of the information leakage brought by removable storage device, the paper designed and implemented the anti-leak security system based on C\S architecture. The system taken filter driver technology to provide fine-grained and flexible access control over removable storage devices and file transparent encryption and decryption, and implemented the effective monitoring of removable storage devices...
Modeling software requirements is one of the grand challenges of ECU (Electronic Control Unit) development for vehicular applications. One of the main problems in this domain is: How to organize the large amount of complicated software requirements with a concise and manageable means. EAST-ADL2, as an architecture description language dedicated to automotive electronic systems, is well-suitable for...
An ETC system based on RFID technology uses radio wave to identify cars passing through the toll collection site and automatically debits toll rate from the car owner's pre-paid account. RFID technology and its application in highway ETC system is analyzed in this paper. SNMP is a kind of protocol that has been widely used in network management system for many years. Because of its easy use and strong...
Based on the analysis of the basic principles and performance requirements of embedded monitoring system, combining with embedded technology, image compression technology and network technology, this paper designs and implements an ARM-based embedded network video monitoring system to achieve video image acquisition, compression and transmission. This system is a small, low cost, digital monitoring...
With the growing needs for advanced functionalities in modern embedded systems, it is now necessary to integrate multiple processors in the system, preferably on a single chip, to support the required computing complexity. The problem is that such multiprocessor system-on-chip (MPSoC) architecture is very complex and its internal behavior is very difficult to track. An effective tool for profiling...
The implementation of a verification environment to check the behavior of a device-under-test using SystemC infrastructure is presented in this paper. SystemC is generally adopted in a system-level design methodology because of the capability of architectural model description and hardware/software co-design. The verification system implemented in this paper can explore design space using SystemC...
An ECG monitoring system comprised of six wearable textile-based electrodes is used to detect the ECG and sitting posture of vehicle drivers. The electrodes are washable, comfortable, sewed into ordinary shirt, and not connected with extra wires; as a result, they not only detect drivers' ECG while they move, but also prevent hindering their driving. While drivers change the sitting postures, different...
Systems capable of monitoring the biological condition of a driver and issuing warnings during instances of drowsiness have recently been studied. Moreover, many researchers have reported that biosignals, such as brain waves, pulsation waves, and heart beat are different between people who have and have not consumed alcohol. Currently, we are developing a noninvasive system to detect individuals driving...
In this paper an approach to testbench development for synchronous parallel-pipeline designs is considered. The approach is based on cycle-accurate formal specifications of a design under verification. Specifications include descriptions of control flow graphs of the design's operations and definitions of the microoperations with the help of Hoare triples. The approach allows to automate testbench...
In this paper, the video sever system is designed centered on IME6410. Based on the platform of embedded processor and Linux, after analyzing the internal relations among Video4Linux(V4L) specification, video driver and kernel of Linux, we propose a common method for driver development accord with V4L Specification.
