The efforts in this area, however, typically use ad-hoc software infrastructures to facilitate and support the system-level DSE experiments. In this paper, we present a new, generic system-level MP-SoC DSE infrastructure, called NASA (Non Ad-hoc Search Algorithm). This highly modular framework uses well-defined interfaces to easily integrate different system-level simulation tools as well as different combinations of search strategies in a simple plug-and-play fashion. Moreover, NASA deploys a so-called dimension-oriented DSE approach, allowing designers to configure the appropriate number of, possibly different, search algorithms to simultaneously co-explore the various design space dimensions. As a result, NASA provides a flexible and re-usable framework for the systematic exploration of the multi-dimensional MP-SoC design space, starting from a set of relatively simple user specifications. To demonstrate the distinct aspects of NASA, we also present several DSE experiments in which we, e.g., compare NASA configurations using a single search algorithm for all design space dimensions to configurations using a separate search algorithm per dimension. These experiments indicate that the latter multi-dimensional co-exploration can find better design points and evaluates a higher diversity of design alternatives as compared to the more traditional approach of using a single search algorithm for all dimensions.||URI:||http://hdl.handle.net/10553/49289||ISBN:||9781424490868||DOI:||10.1109/ESTMED.2010.5666979||Source:||2010 8th IEEE Workshop on Embedded Systems for Real-Time Multimedia, ESTIMedia'10 (5666979), p. 41-50|
