\subsubsection*{Positioning and continuity with other projects}
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
    that 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.
    It provides also embedded operating systems and software/hardware
    communication middleware.
  \item[ROMA] The ROMA ANR project (2007-2010) \cite{roma,RAFFIN:2010:INRIA-00539874:1}
    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 faster or more
    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.
%    and datapath merging techniques to the synthesis of customized
%    ASIP processors.
  \item[TSAR]
     The TSAR MEDEA+ project (2008-2010) involving BULL, THALES and \upmc targets the design of a 
%    The TSAR MEDEA+ project (2008-2010) targets the design of a 
    scalable, coherent shared memory, multi-cores processor architecture, and uses the SoCLib
    platform for virtual prototyping. COACH will benefit from the synthesizable VHDL 
    models developed 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 (ANR BioWic project 2009-2011), so as to
    be able to validate the framework on real-life HPC applications.

  \item[SoCket] 
    The design flow defined in this project targets the design of critical embedded systems. 
    It covers important steps as system architecture exploration, and the definition of virtual
    prototypes at different levels of abstraction to support early embedded software development, 
    verification of hardware blocks, and preparation of certification activities.
    COACH solutions and engines will be specified to be integrated into this standard flow. 
    MDS, Thales TRT, TIMA are already collaborating in this project.

  \item[HOSPI]  
     The objective of this project (with TIMA and MDS) was to define innovative methods, and implement the associated tools, to ease
     the mapping of data-streaming applications on heterogeneous platforms. COACH will use the abstracted description 
     format based on IP-XACT for hardware platforms and the results concerning the integration of code generators into a standard design flow.

  \item[SoftSoC] 
     TIMA and MDS are involved in this project which aims at the
     definition and generation of Hardware Dependent Software layers of a
     system.
     Crucial extensions of the IP-XACT standard will be reused from this
     project, as well as code generation techniques based on them.

\end{description}

The partners involved in the COACH project have a well established expertise
in the following 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
    developed by the \ubs laboratory, and with the UGH~\cite{ugh08} project developed
    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 developed 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.
  \item
    Regarding industrial flow integration \mds will bring its strong expertise
    in IEEE 1685 (IP-XACT) standard. The \mds team is involved and contributes actively
    to it since 2003 and the Magillem tool suite is used for its validation. Magillem is used in 
    industrial production flows of ST, NXP, TI, Qualcomm, and system integrators like Thales, 
    Astrium, Thomson, etc. This guarantees a strong alignement on customers needs and enhanced results exploitation.

\subsubsection*{Relevance to the call axis}
This project answer to the global statement of the call "INGENIERIE NUMERIQUE ET SECURITE (INS)" by proposing 
methods and tools for the design of application to be run on platforms of the next generation. 
Improvements can be expected for productivity, 
time-to-market (automation and code generation) and reliability (management of high level specifications down to implementation).
In this call, the COACH project totally fulfills the objectives of the axis 2 "METHODES,
OUTILS ET TECHNOLOGIES POUR LES SYSTEMES EMBARQUES".
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 automatically generated hardware accelerators. It will also permit to use 
efficiently different dynamic system management techniques and re-configuration mechanisms.
The results will be tailored in order to be integrated in standard design flow of critical systems.
\\
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). 
\parlf
The COACH project has been also shaped to answer to the axis 5 "USAGES".
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. 
%
The results of the COACH project will help users to build cryptographic secure systems implemented in
in a combination of hardware and software in an effective way, substantially enhancing the
productivity of the field, improving the
quality and reducing the design time and the cost of synthesised cryptographic devices.
%
COACH will contribute to enhance the safety in design of critical system for two main reasons:
\begin{itemize}
  \item by providing a way to automate the mapping of application onto MPSoC
  architecture; code generators of the tool chain will be subject to
  certification.
  \item by relaying on design flow defined by SoCKET, which is dedicated to
  safety of critical systems, COACH will benefit from features related to
  requirements traceability.
\end{itemize}

Finally, it is worth noting that this project covers priorities defined by the commission 
experts in the field of Information Technologies Society (IST) for Embedded
Systems: \textit{ $<<$Concepts, methods and tools for designing systems dealing with systems complexity
and allowing to apply efficiently applications and various products on embedded platforms,
considering resources constraints (delays, power, memory, etc.), security and quality
services$>>$}.
