Yet narrow I/O channels, scarce memory and processor resources, real-time and interrupt-driven behavior, and low-level source languages make state-of-the-art validation techniques much more difficult in an embedded context. For students, for whom testing is often already a secondary concern, the challenges in methodical testing of embedded systems can appear insurmountable. We present the Xinu External Suite Tester (XEST) framework, a tool for automated, parallelized regression testing of embedded software kernels running directly on real embedded hardware. We discuss the requirements for such a system, and evaluate its power as both a quality control mechanism in an actively developing system and as an assessment tool for students in conjunction with the Embedded Xinu experimental laboratory.","PeriodicalId":121254,"journal":{"name":"Workshop on Embedded and Cyber-Physical Systems Education","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115473467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we summarize the \"red flag\" issues found in approximately 90 design reviews of embedded system products conducted over a ten year period across a variety of embedded system industries. The problems found can be roughly categorized into the areas of process, requirements, architecture, design, implementation, verification/validation, dependability, project management, and people. A few problem areas, such as watchdog timers and real time scheduling, are standard embedded education topics. But many areas, such as peer reviews, requirements, SQA, and user interface design might be worthy of increased attention in texts and education programs.","PeriodicalId":121254,"journal":{"name":"Workshop on Embedded and Cyber-Physical Systems Education","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123071854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This activity aims to provide an opportunity to learn elementary knowledge and skills of embedded system technologies through a practice of whole development process. Communication skills of participants can be enhanced by an interchange among them of different universities and companies through a group work. In this paper, we introduce a learning curriculum and contents of SSEST. Our curriculum consists of prior individual training and boot camp.

Furthermore, we demonstrate-for the first time-Python booted on NXT using an embedded Python project. Lego Mindstorms NXT is based on an ARM7 micro processor, and it comes with open source C code. There now exists a number of firmware replacements which permit programming NXT with different languages. One of these possibilities are Java, and we combine that solution with an Eclipse plugin for team programming in Java. We demonstrate the system and provide reasons why it is worthwhile to do this in computer science classes. Python is a popular scripting language. It is often used in relation to a larger operating system, and rarely as an operating system itself. In this paper we also demonstrate that it is possible to run Python directly on an embedded processor. We use the open source project PyMite as a proof-of-concept. Lego Mindstorms NXT comes with an open source operating system and together with the open source project nxtgcc, it becomes possible to boot Python on NXT.","PeriodicalId":121254,"journal":{"name":"Workshop on Embedded and Cyber-Physical Systems Education","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124047934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a multi-core SID-based simulation framework useful for exercises and hands-on labs for embedded multi-core courses. The SID is a component-based simulation framework upon which a set of simulation components, such as processors, memory, DMAs, LCDs, and other peripherals are built. Our tool includes ingenious MPU IP, and PAC DSP IP with distributed register files. Each of the components is attached with an interconnection adaptor. The adaptor in our design enables the simulation to be done in the functional layer or in the TLM layer for the interconnection networks. Besides, the communication performance of the system can be evaluated in different types of interconnection networks. In addition, our tool supports profiling capability and time-reversible execution, which enables a rich set of experiments in teaching embedded multi-core courses. Finally, we also present a set of possible courses to be based on this set of tools.","PeriodicalId":121254,"journal":{"name":"Workshop on Embedded and Cyber-Physical Systems Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125897007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It gives third semester bachelor students a first impression on creating embedded software. The course has to be attended by all undergraduate students. Due to the increasing number of students in computer science this will be up to 250 students, which is one of the biggest challenges of this course. In addition to embedded programming many system software concepts are practically implemented in this lab course.

This is also reflected in a close collaboration with Intel Braunschweig Labs, who have sponsored a chair in VLSI system design to complement the curriculum in that field.
