This paper presents a method of HD video coding based on ReMAP reconfigurable processor. The dynamic stream reconstruction technology is used to realize the time-sharing of multiple key sub-algorithms such as integer motion estimation and intra-loop algorithm in reconfigurable processor Multiplex mapping. Simulation results show that reconfigurable processor ReMAP can support the high performance of high-definition video coding. On the other hand, dynamic reconfigurable technology can effectively improve the utilization of reconfigurable processors and make full use of the reconfigurable processor Ability to reduce the need for algorithms to temporarily store data in the middle of storage.
