  \subtask
    The application that \bull proposes is HPC oriented.
    The domain of the application is the treatment of medical images (e.g. image noise
    reduction and camera calibration).
    Our expectation from COACH project is to enhance the \bull HPC solutions that
    are currently based on multi-cores and GPUs with fine grain parallelism on FPGA.

  \subtask The objective of this sub-task is to specify the application and to develop the
    high level code. The application is in the domain of surveillance of critical
    infrastructures.
    The objective is to detect and classify the presence of humans in the restricted area.
    The algorithm is based on the work of Viola and Jones\cite{thales-viola}.
    It implements in particular a cascade of classifiers operating on Haar like features,
    where simple weak classifiers at the beginning of the cascade reject a majority of
    void sub-windows, before more complex classifiers concentrate on potential regions of
    interest.
    This application is computation intensive and also makes an intensive use of binary
    decision trees to cascade the filters, which makes it a good candidate to assess the
    association of CAL with parallelizing tools.\\
    Moreover, the higher levels of computing can involve tracking and data fusion between
    several camera streams and some other informations.
    The targeted system will be composed of one camera connected to a PC.
    All the computing part of the application is executed on a FPGA board connected to the
    PC.

  \subtask \TRT will use its internal software environment tool SPEAR DE to describe the
    application. The tool is able to partition and to generate the code for the target. \\
    In this task, we will adapt SPEAR DE to generate the application description input of
    COACH framework. We will also describe the three templates of architecture in order to
    be able to partition the application on the architecture.

    its ability to generate a whole VHDL of an embedded system on FPGA for an application
    mixing control and data flow aspects. \TRT will evaluate the performance of the
    generated system in terms of GOPS, and the design time from a high level description.

  \subtask FLEXRAS proposes a SoC architecture integrating an embedded FPGA (eFPGA).
    The architecture is composed essentially of a processor, a bus and several RAMs.
    The embedded FPGA is connected to the bus and communicates with the other components.
    The (eFPGA) works in 2 modes:
    \begin{description}
      \item[Slave mode]
        As a DMA, the processor will send the configuration bitstream
        stored on the RAM to the eFPGA. In this mode, the eFPGA is considered as a
        writeable memory and is configured by the processor.
      \item[Master mode]
        Once the FPGA is programmed, it becomes a coprocessor achieving the aimed task.
    \end{description}
      The top architecture of this SoC based-platform will be generated using COACH
      framework. The application that will be run on the SoC corresponds initially to a
      graph of software tasks. Critical tasks will be identified and transformed
      automatically to hardware tasks using COACH high level synthesis feature. While
      software tasks will be run on the processor, hardware ones will be mapped on eFPGA
      to take advantage of its optimized resources and parallelism. FLEXRAS provides all
      the flow from RTL synthesis to bitstream generation.
    \begin{livrable}
      \itemL{0}{6}{d}{\Szied}{\zied architecture}{2.4:0:0}

      \itemL{6}{18}{h}{\Szied}{eFPGA/VCI component}{3.6:3.6:0}

        throught a basic application.
        This applicattion will containt 3 communicating tasks under the COACH format specified
        in {\novers{\specGenManual}} delivrable.
        The first one is a hardware task generated by the HAS tools and transformed into
        a bit stream by the \zied tools.
        The second is a bitstream loader that will load the bitstream of the first task on
        the eFPGA.

  \subtask
  The \navtel Embedded Supper Computing (ESC) project is based on simple hardware but tightly
  coupled module between ARM processor and FPGA.
  The ESC can function on different topologies: Single, parallel or Grid computing modes for
  industrial and scientific applications.
  The ARM and FPGA configuration also facilitate the co-simulation which allows to  gain
  time on the development and integration phase.
  The architecture consists of a wrapper that encapsules computing units depending on the
  application and a real time kernal for task switching and partial reconfiguration of FPGA
  on run time environment.
  \parlf
  To day \navtel develops these computing units manually.
  \navtel expects to benefit from the COACH project especially the HLS tools for
  generating the computing unit.
