2The COACH proposal addresses directly the \emph{Embedded Systems} item of
3the ARPEGE program. It aims to propose solutions to the societal/economical challenges by
4providing SMEs novel design capabilities enabling them to increase their
5design productivity with design exploration and synthesis methods that are placed on top
6of the state-of-the-art methods.
7This project proposes an open-source framework for mapping multi-tasks software applications
8on Field Programmable Gate Array circuits (FPGA).

11COACH will contribute to build an open development and run-time
12environment, including communication middleware and tools to support
13developers in the production of embedded software, through all phases of the software lifecycle,
14from requirements analysis downto deployment and maintenance.
15More specifically, COACH focuses on:
16\begin{itemize}
17\item High level methods and concepts (esp. requirements and architectural level) for system
18design, development and integration, addressing complexity aspects and modularity.
19\item Open and modular development environments, enabling flexibility and extensibility by
20means of new or sector-specific tools and ensuring consistency and traceability along the
21development lifecycle.
22\item Light/agile methodologies and adaptive workflow providing a dynamic and adaptive
23environment, suitable for co-operative and distributed development.

88The laboratories involved in the COACH project have a well estabished expertise
89%in the following domains:
90in the domains:
91\begin{itemize}
92  \item 
93    In the field of High Level Synthesis (HLS), the project
94    leverages on know-how acquired over the last 15 years with the GAUT~\cite{gaut08} project
95    developped by the \ubs laboratory, and with the UGH~\cite{ugh08} project developped
96    by the \upmc and \tima laboratories.
97  \item
98    Regarding system level architecture, the project is based on the know-how
99    acquired by the \upmc and \tima laboratories in the framework of various projects 
100    in the field of communication architectures for shared memory multi-processors systems
101    (COSY~\cite{cosy}, DISYDENT~\cite{disydent05} or DSPIN~\cite{dspin08} of MEDEA-MESA).
102    As an example, the DSPIN project is now used in the TSAR project.
103  \item
104    Regarding Application Specific Instruction Processor (ASIP) design, the
105    CAIRN group at INRIA Rennes -- Bretagne Atlantique benefits from several years of
106    expertise in the domain of retargetable compiler
107    (Armor/Calife~\cite{CODES99} since 1996, and the Gecos
108    compilers~\cite{ASAP05} since 2002).
109\item
110    In the field of compilers, the Compsys group was founded in 2002
111    by several senior researchers with experience in
112    high performance computing and automatic parallelization. They have been
113    among the initiators of the polyhedral model, a theory which serve to
114    unify many parallelism detection and exploitation techniques for regular
115    programs. It is expected that the techniques developped by Compsys for
116    parallelism detection, scheduling, process construction and memory management
117    will be very useful as a front-end for the a high-level synthesis tools.

121The COACH project answers to several of the challenges found in different axis of the
122call for proposals.%Keywords of the call are indicated below in italic writing.
123\begin{description}
124\item[Axis 1] \textit{Architectures des syst\`{e}mes embarqu\'{e}s} \\
125COACH will address new embedded systems architectures by allowing the design of
126Multi-Core Systems-on-Chip (possibly heterogeneous) on FPGA according to the design
127constraints and objectives (real-time, low-power). It will permit to design  complex SoC
128based on IP cores (memory, peripherals, network controllers, communication processors),
129running Embedded Software, as well as an Operating System with associated middleware and
130API and using hardware accelerator automatically generated. It will also permit to use
131efficiently different dynamic system management techniques and re-configuration mechanisms.

134\item[Axis 2] \textit{Infrastructures pour l'Internet, le calcul intensif ou les services} \\
135COACH will address High-Performance Computing (HPC) by helping designer to accelerate an
136application running on a PC by migrating critical parts into a SoC implemented on an FPGA
137plugged to the PC bus (through a communication link like PCI/X). COACH will reduce the designer
138effort through the development of tools that translate high level language programs to FPGA
139configurations. Moreover, Dynamic Partial Reconfiguration will be used for improving HPC performance
140as well as reducing the required area.
