摘要： A boundary macroblock of a video object is padded without significant synchronization overhead between a host processor and an existing coprocessor. The host processor determines horizontal and vertical graphics primitives as a function of shape data stored in a host memory. The shape data determine whether a dot, a line, or a rectangle primitive should be used to pad transparent pixels in the macroblock. The host processor communicates the primitives to a coprocessor, which renders the primitives in an interleaved pipeline fashion to pad transparent pixels of the macroblock based on texture data stored in video memory. The flow of primitives is in one direction from the host processor to the graphics coprocessor, and the texture data is not transferred back and forth between the host processor and coprocessor. This technique is especially useful for enabling acceleration of MPEG-4 video decoding utilizing existing coprocessors capable of accelerating MPEG-1/2 video decoding.
摘要翻译：视频对象的边界宏块在主机处理器和现有的协处理器之间被填充而没有显着的同步开销。主处理器根据存储在主机存储器中的形状数据确定水平和垂直图形基元。形状数据确定是否应使用点，线或矩形基元来填充宏块中的透明像素。主机处理器将原语传送到协处理器，协处理器以基于交织的流水线方式呈现原语，以便基于存储在视频存储器中的纹理数据来缓冲宏块的透明像素。原语的流程在主处理器到图形协处理器的一个方向上，并且纹理数据不会在主处理器和协处理器之间来回传送。该技术对于使用能够加速MPEG-1/2视频解码的现有协处理器的MPEG-4视频解码的加速特别有用。
