This paper introduces the design of an embedded vehicle wireless data transmission system utilizing embedded microprocessor unit AU1200, presenting its implementation based on the embedded linux operating system.We design keys to control GUI which is designed with QT/E, and test the validity of the scheme for this wireless data transmission system in the scope of Wi-Fi Mesh.
Network applications based on embedded platform is becoming more and more popular nowadays. In this paper, a SIP phone based on embedded system is designed and implemented. The embedded processor is S3C2410 which is an ARM-based device and operating system is embedded Linux. By expanding various peripherals, the whole hardware structure is constructed; by porting SIP protocols and analyzing SPEEX...
Because of the limits of the embedded Linux development board resources, it is impossible to operate, develop and debug the tool in development board. For ldquohost + targetrdquo form of compiling and debugging, the host needs to set up an across compiling circumstances suitable to the target machine. The program is compiled, connected and localized on the host, and the executive file obtained can...
Todaypsilas CMP platforms are designed to be symmetric in terms of platform resources such as shared caches. However, it is becoming increasingly important to understand the performance implications of asymmetric caches for two key reasons: (a) multi-workload scenarios such as server consolidation are a growing trend and contention for shared cache resources between workloads causes logical cache...
In various Internet applications based on client/server architecture, it is better to use embedded Web server other than PC server for decreasing volume, cost and power consumption. The paper introduces the design of Web server based on ARM processor, and analyzes hardware configuration and software implementation. Also it discusses the selection of embedded operating system and the working flow of...
Multi-core and chip-level multi-threading systems face serious challenges related to performance scaling. Their performance is dominated by I/0 bus crossings, cache misses and interrupts. In this article we analyse the performance characteristics of typical server systems utilising Sun Niagara T1, Intel Pentium D and AMD Opteron CPUs. Based on our results, we conclude that highly parallel CMT systems,...
