Finding the best possible encoding decisions for compressing a video sequence is a highly complex problem. In this work, we propose a multi-objective Design Space Exploration (DSE) method to automatically find HEVC encoder implementations that are optimized for several different criteria. The DSE shall optimize the coding mode evaluation order of the mode decision process and jointly explore early...
Task-accurate performance estimation methods are widely applied in early design phases to explore different architecture options. These methods rely on accurate annotations generated by software profiling or real measurements to guarantee accurate results. However, in practice, such accurate annotations are not available in early design phases due to lack of source code and hardware platform. Instead,...
Static and dynamic variations, which have negative impact on the reliability of microelectronic systems, increase with smaller CMOS technology. Thus, further downscaling is only profitable if the costs in terms of area, energy and delay for reliability keep within limits. Therefore, the traditional worst case design methodology will become infeasible. Future architectures have to be error resilient,...
This paper introduces a new method to watermark FPGA cores where the signature (watermark) is detected at the power supply pins of the FPGA. This is the first watermarking method, where the signature is extracted in this way. The authors were able to sign cores at the netlist as well as the bitfile level, so a wide spectrum of cores can be protected. The power watermarking method works with all types...
