摘　　要：本文针对块匹配运动估计快速搜索算法的要求,设计了一种算法可编程的运动估计及运动补偿协处理器。该协处理器设计采用软硬件协同处理结构。灵活的指令集和高效的硬件并行执行单元相结合,使得该协处理器具备可编程处理器结构及树形结构运动估计VLSI结构的优点,可以兼顾运动估计算法高处理效率和灵活性的要求。设计的协处理器不拘泥于某种快速搜索算法,通过改变内部程序代码,可以实现多种快速运动估计算法,包括TSS、DS、HEXBS、MVFAST、EPZS等,同时具备很强的可扩展性。与同类设计相比,本设计具有高效、灵活、算法可配置的特点,同时设计消耗的硬件资源也大幅减小。A novel algorithm programmable motion estimation and motion compensation co-processor, which is aimed to implement fast block match motion estimation algorithms effectively, is presented in this paper. This co-processor design adopts the SW/HW co-operating architecture. With the flexible instruction-set and high-efficiency executing parallel hardware, the proposed design shares the advantages of the flexibility of programmable processor and the high-efficiency of full-logic motion estimation implementation. The fast motion estimation algorithm can be realized in means of program, which makes lots of algorithms to be implemented in the proposed co-processor, such as DS, HEXBS, MVFAST, EPZS etc. Compared with traditional motion estimation co-processor design, the proposed design is more flexible and more efficiency with less hardware resource.
