12\begin{objectif}
13This task deals with the COACH HPC feature that consists in accelerating an existing
14application running on a PC by migrating critical parts into a SoC implemented on an
15FPGA plugged to the PC PCI/X bus (figures~\ref{coach-flow} and \ref{archi-hpc}).
16It consists in:
17\begin{itemize}
18\item Specifying and implementing the communication schemes between the software
19  part running on the PC and the FPGA-SoC.
20\item Providing a performance analysis tool helping user in the HPC partitioning
21  (figure~\ref{archi-hpc}).
22\item Providing support for configuration of the FPGA in order to set up the HPC environment.
23\end{itemize}
24The low level hardware transmission support will be the PCI/X bus which allows high bit-rate
25transfers. The reasons of this choice are that both \altera and \xilinx provide PCI/X IP for
26their FPGA and that GPU HPC softwares use also it.
27%This will allow us at least to be inspired by GPU communication schemes and may be to reuse
28%parts of the GPU softwares.
