Guaranteeing that the worst-case scenario has been covered for each basic block individually is a major challenge in measurement-based WCET analysis. On the static analysis side the accuracy of hardware models used are also subject to doubt as they are based on available documentation provided by vendors which may be not detailed enough nor correct or both.(More)
Instruction selection is a compiler optimisation that translates the intermediate representation of a program into a lower intermediate representation or an assembler program. We use the SSA form as an intermediate representation for instruction selection. Patterns are used for translation and are expressed as production rules in a graph grammar. The(More)
Today's most challenging application of computer graphics is the rendering of real scale scenes at photorealistic quality. As this task needs a lot of computing resources, numerous techniques have been applied to speed up rendering, one of these being parallel processing. This paper presents our approach to the efficient parallelization of different(More)
INTRODUCTION The trend towards submillisievert CT scans leads to a higher dose fraction of localizer radiographs in CT examinations. The already existing technical capabilities make dose optimization of localizer radiographs worthwhile. Modern CT scanners apply automatic exposure control (AEC) based on attenuation data in such a localizer. Therefore not(More)
This paper introduces the Internet Operating Platform (IOP), an enterprise framework for large scale software development. In addition to obeying to important standards (UML, XML, Java) an enterprise framework has to fulfil three basic requirements. First of all, it has to be broad and needs an elaborate architecture complementing standards and technologies(More)
