Functional Validation of AADL Models via Model Transformation to SystemC with ATL

6 pagesInternational audienceIn this paper, we put into action an ATL model transformation in order to automatically generate SystemC models from AADL models. The AADL models represent electronic systems to be embedded into FPGAs. Our contribution allows for an early analytical estimation of energetic needs and a rapid SystemC simulation before implementation. The transformation has been tested to simulate an existing video image processing system embedded into a Xilinx Virtex5 FPGA

A modeling and code generation framework for critical embedded systems design: From Simulink down to VHDL and Ada/C code

International audienceThe P project gathers industrial and academic partners to address the issue of a modeling approach and automatic code generation for critical embedded systems. Works target the definition of an open design flow which integrates qualified tools to produce both hardware and software implementations. This paper introduces the project through two code generators that allow generating Ada, C and VHDL from Simulink. Application of the design flow to two industrial case studies is finally presented

Open-PEOPLE, A Collaborative Platform for Remote & Accurate Measurement And Evaluation of Embedded Systems Power Consumption

International audienceThis paper presents Open-PEOPLE, a hardware and software platform which aims to widen access to accurate power consumption measurement to the scientific community. The idea behind this platform is to centralize and abstract the instrumentation effort and the investment cost then allow geographically remote users to make power measurement remotely without requiring any specific costly hardware and/or softwar

An Efficient Framework for Power-Aware Design of Heterogeneous MPSoC

International audienceCurrently, designing low-power complex embedded systems is a main challenge for corporations in a large number of electronic domains. There are multiple motivations which lead designers to consider low-power design such as increasing lifetime, improving battery longevity, limited battery capacity, and temperature constraints. Unfortunately, there is a lack of efficient methodology and accurate tool to obtain power/energy estimation of a complete system at different abstraction levels. This paper presents a global framework for power/energy estimation and optimization of heterogeneous multiprocessor system-on-chip (MPSoC). Within this framework, a power modeling methodology is defined, and an open platform is developed. Our methodology takes into account all the embedded system relevant aspects; the software, the hardware, and the operating system. The platform stands for Open Power and Energy Optimization PLatform and Estimator (Open-PEOPLE). It includes diverse estimation tools with respect to their abstraction levels in order to cover the overall design flow. Starting from functional estimation and down to real boards measurements, our platform helps designers to develop new power models, to explore new architectures, and to apply optimization techniques in order to reduce energy and power consumption of the system. The usefulness and the effectiveness of the proposed power estimation framework is demonstrated through a typical embedded system conceived around the Xilinx Virtex II Pro FPGA platform
