Partially reconfigurable entropy encoder for multi standards video adaptation
N. Marques, Hassan Rabah, Eric Dabellani, Serge Weber · 2011
This paper presents a reconfigurable entropy encoder for real time adaptation of multi-standard compressed video stream. The proposed architecture is based on partial and dynamic reconfiguration. Static and dynamic wrappers are defined to encapsulate different types of entropy coders. A partitioning of reconfigurable area is also presented aiming at the optimization of reconfiguration overhead. The obtained results show a significant gain in silicon area compared to a solution without reconfiguration and a significant gain in reconfiguration time.
