%------------------------------------------------

\begin{frame}
\frametitle{Who am I?}
\begin{itemize}
\item Elie Tournier
\item Google Summer of Code 2016 Student
\item Graduate Software and Image Processing Engineer
\item Available for hire
\end{itemize}
\end{frame}

%------------------------------------------------
\section{The project}
%------------------------------------------------

\begin{frame}
\frametitle{Goal}
\begin{itemize}
\item Iago Toral bring GL\_ARB\_gpu\_shader\_fp64 to Intel GPUs.
\item A stretch goal would be to create GL\_ARB\_gpu\_shader\_fp64 for GPUs without FP64 hardware support.
\item Create a FP64 support
\end{itemize}
\end{frame}

%------------------------------------------------
\section{The work}
%------------------------------------------------

\begin{frame}
\frametitle{GLSL}
\begin{itemize}
\item The library is written in GLSL.
\item Use GLSL in order to use the graphics pipeline without having to use hardware-specific languages.
\item Can be convert to GLSL IR thanks to the standalone compiler.
\item Like I need to use bitwise operators, GPUs must be GLSL 1.30 (OpenGL 3.0).
\end{itemize}
\end{frame}

%------------------------------------------------

\begin{frame}
\frametitle{Choose a CPU lib}
\begin{itemize}
\item I don't want to reinvent the wheel.
\item Convert a CPU library to a GPU one.
\item Berkeley SoftFloat by John R. Hauser.
\item IEEE 754 compliant.
\end{itemize}
\end{frame}

%------------------------------------------------
\section{The dev}
%------------------------------------------------

\begin{frame}
\frametitle{Dev environment}
\begin{itemize}
\item Code in my GitHub.
\item Use Shader\_runner from Piglit.
\item Debug and test shaders.
\end{itemize}
\end{frame}

%------------------------------------------------

\begin{frame}[fragile] % Need to use the fragile option when verbatim is used in the slide
\frametitle{Store FP64}
\begin{example}[Code Berkley SoftFloat]
\begin{verbatim}
typedef struct {
   !!!bits32 high, low;
} float64;
\end{verbatim}
\end{example}

\begin{example}[Code libSoftFloat]
\begin{verbatim}
uvec2 fp64;
\end{verbatim}
\end{example}

\end{frame}

%------------------------------------------------

\begin{frame}[fragile] % Need to use the fragile option when verbatim is used in the slide
\frametitle{Extract FP64 Exp}
\begin{example}[Code Berkley SoftFloat]
\begin{verbatim}
INLINE int16 extractFloat64Exp( float64 a )
{

    return ( a.high>>20 ) & 0x7FF;

}
\end{verbatim}
\end{example}

\begin{example}[Code libSoftFloat]
\begin{verbatim}
uint extractFloat64Exp( uvec2 a )
{

    return ( a.x>>20 ) & 0x7FFu;
    
}
\end{verbatim}
\end{example}

\end{frame}

%------------------------------------------------
\section{Plan}
%------------------------------------------------

\begin{frame}
\frametitle{Plan}
\begin{itemize}
\item Finish to implement last FP64 operations.
\item Integrate the lib to Mesa.
\item Implement GL\_ARB\_gpu\_shader\_fp64.
\end{itemize}
