Title: Implementation of MPEG2 codec with MMX/SSE/SSE2 technology


Because of the ever-increasing multimedia content in desktop
environment, demands for efficient multimedia processing capability is
getting stronger and stronger.  Intel’s MMX/SSE/SSE2 technology is
designed to accelerate multimedia and communications applications.  It
uses SIMD(single instruction multiple data) techniques to exploit the
parallelism in many multimedia and communications algorithms, yet
maintains full compatibility with existing operating systems and
applications. 

MPEG2 is a widely used standard for compressing stream video and audio
data.  It is used in many current consumer applications, most noticeably
HDTV and DVD.  Because of the vast amount of computation an MPEG2 codec
has to perform and its highly regular data access pattern, it is an
ideal target for optimization with MMX/SSE/SSE2 technology.  In our
project, we implement the MPEG2 codec with MMX/SSE/SSE2 technology and
illustrate the performance improvement.
