54\subsubsection*{Positionning and continuity with other projects}
55The COACH project will benefit from a number of previous recent projects:
56\begin{description}
57  \item[SOCLIB]
58    The SoCLib ANR platform (2007-2009) is an open infrastructure
59    that supports system level virtual prototyping of shared memory, multi-processors
60    architectures, and provides tools to map multi-tasks software application on these
61    architectures, for reliable performance evaluation.
62    The core of this platform is a library of SystemC simulation models for
63    general purpose IP cores.
64    It provides also embedded operating systems and software/hardware
65    communication middleware.
66  \item[ROMA] The ROMA ANR project (2007-2010) \cite{roma,RAFFIN:2010:INRIA-00539874:1}
67    involving IRISA (CAIRN team), LIRMM, CEA List, THOMSON France R\&D,
68    proposes to develop a reconfigurable processor, exhibiting high
69    silicon density and power efficiency, able to adapt its computing
70    structure to computation patterns that can be faster or more
71    power efficient.  %The ROMA project study a pipeline of
72    %evolved low-power coarse grain reconfigurable operators to avoid
73    %traditional overhead, in reconfigurable devices, related to the
74    %interconnection network. 
75        The project will borrow from the ROMA
76    ANR project and the ongoing joint INRIA-STMicro
77    Nano2012 project to adapt existing pattern extraction algorithms
78    and datapath merging techniques to ASIP synthesis.
79%    and datapath merging techniques to the synthesis of customized
80%    ASIP processors.
81  \item[TSAR]
82     The TSAR MEDEA+ project (2008-2010) involving BULL, THALES and \upmc targets the design of a
83%    The TSAR MEDEA+ project (2008-2010) targets the design of a
84    scalable, coherent shared memory, multi-cores processor architecture, and uses the SoCLib
85    plaform for virtual prototyping. COACH will benefit from the synthesizable VHDL
86    models developped in the framework of TSAR (MIPS32 processor core, and RING interconnect).
87  \item[BioWic]
88    On the HPC application side, we also hope to benefit from the experience in
89    hardware acceleration of bioinformatic algorithms/workfows gathered by the
90    CAIRN group in the context of the ANR BioWic project (2009-2011), so as to
91    be able to validate the framework on real-life HPC applications.
92
93  \item[SoCket] 
94    The design flow defined in this project targets the design of critical embedded systems.
95    It covers important steps as system architecture exploration, and the definition of virtual
96    prototypes at different levels of abstraction to support early embedded software development,
97    verification of hardware blocks, and preparation of certification activities.
98    COACH solutions and engines will be specified to be integrated into this standard flow.
99    MDS, Thales TRT, TIMA are already collaborating in this project.
100
101  \item[HOSPI] 
102     The objective of this project (with TIMA and MDS) was to define innovative methods, and implement the associated tools, to ease
103     the mapping of data-streaming applications on heterogeneous platforms. COACH will use the abstracted description
104     format based on IP-XACT for hardware platforms and the results concerning the integration of code generators into a standard design flow.
105
106  \item[SoftSoC] 
107     TIMA and MDS are involved in this project, which aims at the standard definition and generation of Hardware Dependent Software layers of a system.
108     Crucial extensions of the IP-XACT standard will be reused from this project, as well as code generation techniques based on them.

112\parlf\noindent
113The partners involved in the COACH project have a well established expertise
114in the following domains:
115\begin{itemize}
116  \item 
117    In the field of High Level Synthesis (HLS), the project
118    leverages on know-how acquired over the last 15 years with the GAUT~\cite{gaut08} project
119    developed by the \ubs laboratory, and with the UGH~\cite{ugh08} project developed
120    by the \upmc and \tima laboratories.
121  \item
122    Regarding system level architecture, the project is based on the know-how
123    acquired by \upmc and \tima in the framework of various projects 
124    in the field of communication architectures for shared memory multi-processors systems
125    (COSY~\cite{cosy}, DISYDENT~\cite{disydent05} or DSPIN~\cite{dspin08} of MEDEA-MESA).
126    As an example, the DSPIN project is now used in the TSAR project.
127  \item
128    Regarding Application Specific Instruction Processor (ASIP) design, the
129    CAIRN group at INRIA Rennes -- Bretagne Atlantique benefits from several years of
130    expertise in the domain of retargetable compiler
131    (Armor/Calife~\cite{CODES99} since 1996, and the Gecos
132    compilers~\cite{ASAP05} since 2002).
133  \item
134    In the field of compilers, the \lip Compsys group was founded in 2002
135    by several senior researchers with experience in
136    high performance computing and automatic parallelization. They have been
137    among the initiators of the polyhedral model, a theory which serve to
138    unify many parallelism detection and exploitation techniques for regular
139    programs. It is expected that the techniques developped by \lip for
140    parallelism detection, scheduling \cite{Feau:92aa,Feau:92bb},
141    process construction \cite{Feau:96} and memory management \cite{bee}
142    will be very useful as a front-end for HLS tools.
143  \item
144    Regarding industrial flow integration \mds will bring its strong expertise
145    in IEEE 1685 (IP-XACT) standard. \mds team is involved and contributes actively
146    to it since 2003 and Magillem tool suite is used for its validation. Magillem is used in
147    industrial production flows of ST, NXP, TI, Qualcomm, and system integrators like Thales,
148    Astrium, Thomson, etc. This guarantees a strong alignement on customers needs and enhanced results exploitation.

152\subsubsection*{Relevance to the call axis}
153This project answer to the global statement of the call "INGENIERIE NUMERIQUE ET SECURITE (INS)" by proposing
154methods and tools for the design of application to be run on platforms of the next generation.
155Inprovements can be expected for productivity,
156time-to-market (automation and code generation) and safety (management of high level sepcifications down to implementation).
157In this call, the COACH project totally fulfills the objectives of the axis 2 "METHODES,
158OUTILS ET TECHNOLOGIES POUR LES SYSTEMES EMBARQUES".
159COACH will address new embedded systems architectures by allowing the design of
160Multi-Core Systems-on-Chip (possibly heterogeneous) on FPGA according to the design
161constraints and objectives (real-time, low-power). It will permit designing  complex SoC
162based on IP cores (memory, peripherals...),
163running Embedded Software, as well as an Operating System with associated middleware and
164API and using automatically generated hardware accelerators. It will also permit to use
165efficiently different dynamic system management techniques and re-configuration mechanisms.
166The results will be tailored in order to be integrated in standard design flow of critical systems.
167\\
168COACH will address High-Performance Computing (HPC) by helping designers to accelerate an
169application running on a PC.
170By providing tools that translate high level language programs to FPGA
171configurations, COACH will allow to easily migrate critical parts into an FPGA plugged to the
172PC bus (through a communication link like PCI/X).
173\parlf
174The COACH project has been also shaped to answer to the axis 5 "USAGES".
175COACH will address robotic and control applications by
176allowing to design complex systems based on MPSoC architecture.
177Like in the consumer electronics domain, future control applications
178will employ more and more SoC for safety and security applications.
179Application domains for such systems are for example automotive
180or avionics domains (e.g. collision-detection, intelligent navigation...).
181Manufacturing technology will also increasingly need high-end vision analysis and high-speed
182robot control.

184The results of the COACH project will help users to build cryptographic secure systems implemented in
185in a combination of hardware and software in an effective way, substantially enhancing the
186productivity of the field, improving the
187quality and reducing the design time and the cost of synthesised cryptographic devices.
