In this paper, we present how it is possible to adapt existing development solutions to provide embedded virtualization advantages. To do so, we use the Hellfire Framework, which offers an integrated tool-flow in which design space exploration (DSE), OS customization and static and dynamic application mapping are highly automated. In this case, the designer can develop embedded sequential and p...

Exploration with a generative formalism must necessarily account for the nature of interaction between humans and the design space explorer. Established accounts of design interaction are made complicated by two propositions in Woodbury and Burrow’s Keynote on design space exploration. First, the emphasis on the primacy of the design space as an ordered collection of partial designs ~version, a...

With the continuous scaling of CMOS technologies, maintaining the microprocessor reliability becomes a major design challenge. In particular, accelerated transistor aging is a serious reliability concern, as it considerably reduces the operational system lifetime. To address this issue, in this work cross-layer solutions for aging modeling, simulation and mitigation are proposed, to be able to ...

We present a framework for area optimal system design space exploration for hypermedia applications. We focus on a category of processors that are programmable yet optimized to a hypermedia application. The key components of the framework presented in this paper are a retargetable instruction-level parallelism compiler, instruction level simulators, a set of complete media applications written ...

Nowadays, embedded systems need to support multiple applications simultaneously. It is not enough anymore to simply use a mobile phone to call somebody, but users also want to be able to simultaneously do other things, like listen to mp3’s or watch videos. This calls for a change in embedded system design which already takes the interaction between the multiple applications into account in the ...

Within Philips Research Labs, we are investigating the 64bit VLIW core for future TriMedia processors. We have performed an extensive Design Space Exploration (DSE) on this core using quantitative analysis, using a benchmark suite of applications which are representative for multimedia processing. We have explored, among others, the configurations of the different functional units (FUs) of the ...

Architectural models of component-based software systems are evaluated for functional properties and/or extrafunctional properties (e.g. by doing performance predictions). However, after getting the results of the evaluations and recognising that requirements are not met, most existing approaches leave the software architect alone with finding new alternatives to her current design (e.g. by cha...

Design space explorers support designers through the metaphor of exploration, a guided movement through a space of possibilities. As systems, design space explorers present a mixed-initiative environment in which designers engage in their work helped by a computer to an extent both computationally possible and desired by the designer. Design space explorers provide a set of generative operators...

Performance is no longer the only metric dominating modern system-level design. Power is emerging as major constraint to consider during system development. Consequently, several CAD tools with power estimation capabilities in addition to performance figures have been developed. Among these tools, UNISIM is a simulation framework that enables the architects to rapidly design a new system at dif...

We present a hardware sharing method for design space exploration of multi-processor embedded systems. In our prior work, we had developed a system-level design tool named SystemBuilder which automatically synthesizes target implementation of a system from a functional description. In this work, we have extended SystemBuilder so that it can automatically synthesize an area-efficient implementat...
