Abstract:The utilisation of fast performance assessment technologies is crucial for bounding the cost of the design of efficient embedded systems. Accuracy is a prime concern, since performance models have to be sufficiently faithful to the actual implementations they reflect. In a design space exploration (DSE) context, sufficiently means that the performance models shall enable design decisions. In this context, this talk shows how native simulation, while providing a qualitative speed-up for DSE, can also preserve an accuracy (.e.g, <10% error vs binary translation in account of simulated instructions in bare processing modelling). This should provide the fidelity required for design space exploration in most scenarios. The generic ideas presented are supported by the experiments performed on top of an actual adaptation and extension of a native simulation tool called VIPPE, in order to enable time and energy estimation of specific target processors.
