Efficient implementation of video post-processing algorithms on the BOPS parallel architecture

Deblocking and deringing are two video post-processing techniques largely used to remove coding artifacts and improve the visual quality when rendering low bit rate coded video. The algorithms used to achieve these tasks are computationally intensive and usually require high speed processors to be able to run in real time. Efficient implementations of signal adaptive filters for video post-processing can be obtained using the specialized features of the parallel BOPS® DSP cores. The performance achieved by deblocking and deringing CIF and SDTV size video sequences on the MANTATM prototype chip are illustrated. It is shown that such complex tasks may be executed at low clock rates using the BOPS ManArrayTM technology.
