CCLI/Type1: VUE: A Versatile Unix Emulator of Embedded Systems for Software Oriented Students

计算机科学(31)我们周围都是嵌入式系统，它们使用软件来控制汽车、家用电器和手机中的设备。全球范围内缺乏具有设计嵌入式系统核心技能的工程师。计算机科学专业的学生很少有机会为嵌入式系统设计有意义的软件。调查人员正在开发一种多功能的Unix Emulator(VUE)来满足这一需求。VUE用于模拟四种软件体系结构：轮询、带中断的轮询、函数队列调度器和实时操作系统软件。VUE创建具有三组进程的应用程序：1)虚拟输入设备，2)虚拟输出设备，3)控制进程。教师通过指定输入、输出设备和事件情景来创建实验练习。学生开发控制嵌入式系统过程的软件，必须考虑能耗和响应性等设计权衡。VUE生成了一系列丰富且可重复的事件，供压力测试学生设计。自动随机事件创建可重复的实验来评估软件质量。预期结果包括模拟器和一系列实验室练习。VUE正在奥本大学和塔斯基吉大学进行试点。提供讲习班，培训教师如何采用这些材料。

Computer Science (31)We are surrounded by embedded systems that use software to control devices in cars, appliances and cell phones. There is a worldwide shortage of engineers with core skills for designing embedded systems. Computer science students rarely have an opportunity to design meaningful software for embedded systems. Investigators are developing a Versatile Unix Emulator (VUE) to address this need. It is used to emulate four software architectures: round robin, round robin with interrupts, function queue scheduler and real-time operating system software.VUE creates an application with three groups of processes: 1) virtual input devices, 2) virtual output devices, and 3) control processes. An instructor creates a laboratory exercise by specifying input, output devices and a scenario of events. Students develop software to control the process of the embedded systems and must consider design trade-offs such as energy consumption and responsiveness. VUE generates a rich and repeatable set of events that stress test student designs. The automated random events create repeatable experiments to evaluate software quality. Expected outcomes include the emulator and a collection of laboratory exercises. VUE is being piloted at Auburn University and Tuskegee University. Workshops are provided to train faculty how to adopt the materials.
