  1. 1. Simplify: an abstract MPSoC platform frameworkfor enabling fast functional/behavioral simulation Gabriel Marchesan Almeida, Oliver Bellaver Longhi, Michael Hübner, Fabiano Hessel and Jürgen Becker www.kit.edu
  2. 2. Motivation Multiprocessor Systems-on-Chips (MPSoCs): popular solution that combines flexibility of software along with potentially significant speedups; They integrate few mid-range microprocessors for which applications are usually statically mapped at design-time; Those applications however tend to increase in complexity and often exhibit time-changing workloads which makes mapping decisions sub-optimal in a number of scenarios; Offline approaches are no longer sufficient as application mapping paradigms, because they do not allow coping with time changing workloads; Institut für Technik der Informationsverarbeitung (ITIV)2 11.10.2012 Dr. Michael Hübner
  3. 3.
