	abstract = "Due to the increasing algorithmic complexity of todays embedded systems, the consideration of extra-functional properties becomes even more important. Extra-functional properties such as timing, power consumption, and temperature need to be validated against given requirements on all abstraction levels. For timing and power consumption at RT- and gate-level, several techniques are available, but there is still a lack of methods and tools for power estimation and analysis at electronic system level (ESL) and above. In todays systems most of the hardware is not design from scratch, but bought as black-box components from IP vendors. Our Power State Machine (PSM) model enables power simulation of these components at ESL by deriving the power of communication at the component’s interfaces. In this work we present an Eclipse plug-in which supports the designer or user of a black-box IP component in creating the PSM model based on gate-level simulations and power estimations."

Extra-functional properties such as timing, power consumption, and temperature need to be validated against given requirements on all abstraction levels. For timing and power consumption at RT- and gate-level, several techniques are available, but there is still a lack of methods and tools for power estimation and analyses at electronic system level (ESL) and above. Existing ESL methods in most cases use state-based methods for power simulation. This may lead to inaccurate results, especially for data-dependent designs. In this paper, we extend the Power State Machine (PSM) model for black-box RTL IP components with a mechanism that employs data-dependent switching activity using the Hamming distance (HD). In pipelined designs, we do not only consider the input HD but also the HDs of the internal pipeline stage registers. Since these registers of black-box IP are not observable from the outside, our model derives the internal HDs from previous input data. The results show that our extension achieves up to 38% better results than the previous PSM approach and up to 35% better results compared to a model considering only the input HD."

	abstract = "The ever rising energy and accordingly cooling demands are a major hurdle for the scalability of todays supercomputers. We are challenged with the need to increase computation performance to cope with the rising complexity of calculations on the one hand and the need to keep the energy/cooling demand stable or in the best case even to reduce it. Recently, one widely discussed way to do this is the integration of heterogeneous computation devices into the supercomputer systems as these tend to have a far better performance/energy ratio for large classes of applications. The obvious drawback of heterogeneous systems is the additional design complexity for the software development in order to efficiently use these devices in terms of performance as well as power. For this reason we propose a flow, which assists the soft-- ware developer at design time, offering immediate power-- and performance--estimation. Such approaches are already known in the embedded world, helping there to select between different design possibilities, and will be used to get the best possible per-- formance from a massively heterogeneous computation platform, while still keeping the energy consumption in mind.",
