After an evaluation comparing leading
high-level synthesis tools, Fraunhofer IIS chose the Catapult C
Synthesis tool based on quality of results, time savings, ease of use,
and the tool's compatibility with the company's C /C++ design flow. This triggered the decision to explore
high-level synthesis to reduce manual development time and validation
effort. It has been the main developer of the
most advanced audio coding schemes , like MP3, MPEG-2 AAC and MPEG-4
AAC (Advanced Audio Coding) and made significant contributions to the
definition, design and implementation of Digital Audio Broadcast DAB,
