COACH will contribute to build an open design and run-time
environment, including communication middleware and tools to support
developers in the production of embedded software, through all phases of the software lifecycle,
from requirements analysis downto deployment and maintenance.
More specifically, COACH focuses on:
\begin{itemize}
\item High level methods and concepts (esp. requirements and architectural level) for system
design, development and integration, addressing complexity aspects and modularity.
\item Open and modular design environments, enabling flexibility and extensibility by
means of new or sector-specific tools and ensuring consistency and traceability along the
development lifecycle.
\item Light/agile methodologies and adaptive workflow providing a dynamic and adaptive
environment, suitable for co-operative and distributed development.
\end{itemize}
COACH outcome will contribute to strengthen Europe's competitive position by developing
technologies and methodologies for product design, focusing (in compliance with the
%scope of the above program) on technologies, engineering methodologies, novel tools,
%methods which facilitate resource use efficiency. The approaches and tools to be developed

The COACH project will benefit from a number of previous recent projects:
\begin{description}
  \item[SOCLIB]
    The SoCLib ANR platform (2007-2009) is an open infrastructure developped by
    10 academic laboratories (TIMA, LIP6, Lab-STICC, IRISA, ENST, CEA-LIST, CEA-LETI, CITI, INRIA-Futurs, LIS) and 6 
    industrial companies (Thales Communications, Thomson R\&D, STMicroelectronics, Silicomp, MDS, TurboConcept). 
    It supports system level virtual prototyping of shared memory, multi-processors
    architectures, and provides tools to map multi-tasks software application on these
    architectures, for reliable performance evaluation.
    The core of this platform is a library of SystemC simulation models for 
    general purpose IP cores such as processors, buses, networks, memories, IO controller.
    The platform provides also embedded operating systems and software/hardware
    communication middleware.
    The synthesisable VHDL models of IPs are not part of the SoCLib platform, and
    COACH will enhance SoCLib by providing the synthesisable VHDL models required
    for FPGA synthesis.
  \item[ROMA] The ROMA ANR project \cite{roma}
    involving IRISA (CAIRN team), LIRMM, CEA List, THOMSON France R\&D,
    proposes to develop a reconfigurable processor, exhibiting high
    silicon density and power efficiency, able to adapt its computing
    structure to computation patterns that can be speed-up and/or
    power efficient.  %The ROMA project study a pipeline of
    %evolved low-power coarse grain reconfigurable operators to avoid
    %traditional overhead, in reconfigurable devices, related to the
    %interconnection network.  
        The project will borrow from the ROMA
    ANR project and the ongoing joint INRIA-STMicro
    Nano2012 project to adapt existing pattern extraction algorithms
    and datapath merging techniques to ASIP synthesis.

%    The TSAR MEDEA+ project (2008-2010) targets the design of a 
    scalable, coherent shared memory, multi-cores processor architecture, and uses the SoCLib
    plaform for virtual prototyping. COACH will benefit from the synthesizable VHDL 
    models developped in the framework of TSAR (MIPS32 processor core, and RING interconnect).
  \item[BioWic]
    On the HPC application side, we also hope to benefit from the experience in
    hardware acceleration of bioinformatic algorithms/workfows gathered by the
    CAIRN group in the context of the ANR BioWic project (2009-2011), so as to
    be able to validate the framework on real-life HPC applications.

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

The COACH project answers to several of the challenges found in different axis of the 
call for proposals.%Keywords of the call are indicated below in italic writing.
\begin{description}
\item[Axis 1] \textit{Architectures des syst\`{e}mes embarqu\'{e}s} \\
COACH will address new embedded systems architectures by allowing the design of 
Multi-Core Systems-on-Chip (possibly heterogeneous) on FPGA according to the design 
constraints and objectives (real-time, low-power). It will permit designing  complex SoC 
based on IP cores (memory, peripherals...), 
running Embedded Software, as well as an Operating System with associated middleware and 
API and using hardware accelerator automatically generated. It will also permit to use 
efficiently different dynamic system management techniques and re-configuration mechanisms.
\textbf{Thereby COACH well corresponds to axis 1}.
%
\item[Axis 2] \textit{Infrastructures pour l'Internet, le calcul intensif ou les services} \\
COACH will address High-Performance Computing (HPC) by helping designers to accelerate an 
application running on a PC. 
By providing tools that translate high level language programs to FPGA 
configurations, COACH will allow to easily migrate critical parts into an FPGA plugged to the 
PC bus (through a communication link like PCI/X). 
Moreover, Dynamic Partial Reconfiguration will be used for improving HPC performance 
as well as reducing the required area.
\textbf{Thereby COACH partially corresponds to axis 2}.

\item [Axis 3] \textit {Robotique et contr\^{o}le/commande}:

COACH will address robotic and control applications by 
allowing to design complex systems based on MPSoC architecture.
Like in the consumer electronics domain, future control applications 
will employ more and more SoC for safety and security applications. 
Application domains for such systems are for example automotive 
or avionics domains (e.g. collision-detection, intelligent navigation...). 
Manufacturing technology will also increasingly need high-end vision analysis and high-speed 
robot control. 
\textbf{Thereby COACH indirectly answers to axis 3}.

\item [Axis 5] \textit {S\'{e}curit\'{e} et suret\'{e}}:

The results of the COACH project will help users to build cryptographic secure systems implemented in
hardware or both in software/hardware in an effective way, substantially enhancing the
process productivity of the cryptographic algorithms hardware synthesis, improving the
quality and reducing the design time and the cost of synthesised cryptographic devices.
\textbf{Thereby COACH indirectly answers to axis 5}.
