| Abstract: | The design and real- time implementation of H.264 high performance video encoder based on ADSP- Blackfin533 platformwas described. Firstly, the design of the hardware was introduced. Then, the encoder program was ported, and some algorithms fo-cused on Inter Prediction were optimized based on the custom video operations and architecture of Blackfin533. |
