Conclusion
Bottleneck for multimedia applications on C6x is bit stream parsing and variable-length decoding
- Bit management routines are only available on S unit
- 75-80% execution time for JPEG
- 50% execution time for baseline MPEG-4 decoding
Integrated development environments
- Texas Instruments Code Composer
- Spectrum Signal extensions to Microsoft Visual C++
C6x benchmarking for speech/audio applications
