Finding the best possible encoding decisions for
compressing a video sequence is a highly complex problem.
In this work, we propose a multi-objective Design Space Exploration
(DSE) method to automatically find HEVC encoder
implementations that are optimized for several different criteria.
The DSE shall optimize the coding mode evaluation order of the
mode decision process and jointly explore early skip conditions
to minimize the four objectives a) bitrate, b) distortion, c)
encoding time, and d) decoding energy. In this context, we use
a SystemC-based actor model of the HM test model encoder
for the evaluation of each explored solution. The evaluation that
is based on real measurements shows that our framework can
automatically generate encoder solutions that save more than
60% of encoding time or 3% of decoding energy when accepting
bitrate increases of around 3%.
