摘要：Virtualization has gained great acceptance in the server and cloud computing arena. In recent years, it has also been widely applied to real-time embedded systems with stringent timing constraints. We present a comprehensive survey on real-time issues in virtualization for embedded systems, covering popular virtualization systems including KVM, Xen, L4 and others.

摘要：Design Patterns, which give abstract solutions to commonly recurring design problems, have been widely used in the software and hardware domain. As non-functional requirements are an important aspect in the design of safety-critical embedded systems, this work focuses on the integration of non-functional implications in an existing design pattern concept. We propose a pattern representation for safety-critical embedded application design methods by including fields for the implications and side effects of the represented design pattern on the non-functional requirements of the overall systems. The considered requirements include safety, reliability, modifiability, cost, and execution time.

摘要：This paper deals with a new hardware/software embedded system design methodology based on design pattern approach by development of a new design tool called smartcell. Three main constraints of embedded systems design process are investigated: the complexity, the partitioning between hardware and software aspects and the reusability. Two intermediate models are carried out in order to solve the complexity problem. The partitioning problem deals with the proposed hardware/software partitioning algorithm based on Ant Colony Optimisation. The reusability problem is resolved by synthesis of intellectual property blocks. Specification and integration of an intelligent controller on heterogeneous platform are considered to illustrate the proposed approach.

摘要：为解决Qt/embedded视频采集过程中图像的连续性和实现过程的简易性,基于ARM-Linux中V4L2(Video forLinux2)视频采集架构模型提出两种设计方案:一是使用Qt/embedded提供的QThread类,将基于Linux视频采集应用程序移植到QT开发的GUI界面上;二是采用其中的QPainter类,直接实现USB视频采集显示。并以第二种方案为例将视频采集GUI发布到嵌入式设备上。以上方案的设计方法对非GUI到GUI的移植具有重要的参考意义,同时对视频图像的后端处理具有实用价值。
