OpenMAX DL: Media Codec Portability

• OpenMAX DL is a library of key static primitive functions
  - Designed to cover 80% of the processing required in a multimedia codec
• Abstracts the ISA from the multimedia codec
  - Enables faster codec development time and faster porting of existing codecs
• Enables third party codec vendors to sell processor-agnostic codecs
  - Multi-core architectures (i.e. ARM + DSP) gain greater code reuse between cores
