    System-On-Chip FPGA Devices for Complex Electrical Energy Systems Control

    1 System-on-Chip FPGA Devices for Complex Electrical Energy Systems Control I. INTRODUCTION IGITAL electronics has become a standard for controlling electrical systems. This is due to the D constant improvement of the digital devices, whether in terms of density, performance, flexibility of use or cost reduction [1]. This paper looks into System-on-Chip (SoC) Field Programmable Gate Array (FPGA) for controlling complex electrical energy systems. These devices encompass multicore floating point microprocessors embedded with standard peripherals together with an FPGA fabric that allows the design of custom peripherals and specific hardware accelerators. Thus, SoC FPGA devices can be regarded as a good compromise between “super” microcontrollers (very fast in terms of computation but with a fixed micro-architecture) and pure FPGAs (ideal for specific concurrent micro-architectures but limited in terms of density). SoC FPGA architectures are discussed and compared with state-of-the-art DSP-controllers, since they can also be qualified as SoC devices as they are integrating floating point microprocessor cores and substantial peripherals. The main differences between these two groups of devices lies in the opportunity offered to the designer by the SoC FPGAs to customize the SoC device via its internal FPGA fabric. Two case studies demonstrate that with SoC FPGAs one can go beyond standard control by introducing new auxiliary functions that enhance market competitiveness. The first application concerns a fuel cell hybrid electric system controlled by passivity-based power management associated with an aging prognosis algorithm. For this application, it is shown that the time and cost constraints justify the use of a soft processor core to implement the controller.

    Test Suite Optimisation Based on Response Status Codes and Measured Code Coverage

    DEPARTMENT OF COMPUTER SCIENCE AND ENGINEERING Tuomas Parttimaa TEST SUITE OPTIMISATION BASED ON RESPONSE STATUS CODES AND MEASURED CODE COVERAGE Master’s Thesis Degree Programme in Computer Science and Engineering April 2013 Parttimaa T. (2013) Test Suite Optimisation Based on Response Status Codes and Measured Code Coverage. University of Oulu, Department of Computer Science and Engineering, Degree Programme in Computer Science and Engineering, Oulu, Finland, Master’s Thesis, 78 pp., 2 Appendices. ABSTRACT A software test suite often comprises of thousands of distinct test cases. There- fore, the execution of an unoptimised test suite might waste valuable time and resources. In order to avoid the unnecessary execution of redundant test cases, the test suite should be optimised to contain fewer test cases. This thesis focuses on the optimisation efforts of a commercially available Hypertext Transfer Proto- col (HTTP) fuzzing test suite. A test setup was created for the optimisation purposes. The test setup con- sisted of the given fuzzing test suite, five different HTTP server implementations used as test subjects, and a code coverage measurement tool. Test runs were ex- ecuted against the five test subjects with the test suite, and at the same time code coverage was measured from the test subjects. In this thesis, three different types of test suite optimisation algorithms were implemented. The original test suite was optimised by applying the optimisation algorithms to the results of the test runs. Another set of test runs were performed with the optimised subset suites, while again measuring code coverage from the same test subjects. All of the coverage measurement results are presented and analysed.

Mit ihm lassen sich in C++ Webanwendungen mit MVC-Architektur programmieren. Olaf Radicke, Tommi Mäkitalo www.linux-magazin.de Tntnet-Applikationen lassen sich grund- sätzlich auf zwei Arten umsetzen. Entwe- der kommt ein Tntnet-Application-Server zum Einsatz, um Shared Libraries und Objektdateien zu laden und auszuführen, oder man erzeugt ein einziges lauffähiges Binary. Im ersten Fall besteht die Ap- plikation aus einer Shared Library und dem Tntnet-Application-Server. Im zwei- ten Fall lässt sich alles zu einer einzigen ausführbaren Datei zusammenfassen, was das Ausrollen vereinfacht, etwa auf Embedded-Geräten. Dieser Artikel ver- wendet die zweite Variante. Zur Ansicht © nomadsoul1, 123RF.com © nomadsoul1, Das Tntnet-Framework nutzt die ver- breitete Anwendungsarchitektur Model Im Magazin-Schwerpunkt 11/13 [1] durf- sourcen-schonend.
