使用软件驱动器及硬件驱动器彼此联合来实现混合视频编码器的方法及装置
摘要：
一种视频编码方法，包含：由软件驱动器执行多个指令来处理视频编码操作的第一部分，其中该视频编码操作的第一部分包含至少运动估计功能；输送该运动估计功能产生的运动估计结果至硬件驱动器；以及由该硬件驱动器处理该视频编码操作的第二部分。一种视频编码方法，包含：由软件驱动器执行多个指令以及高速缓存来处理视频编码操作的第一部分；由硬件驱动器处理该视频编码操作的第二部分；通过该高速缓存处理该软件驱动器与该硬件驱动器之间的数据传输；以及执行地址同步来保证该高速缓存的同一输入是由该软件驱动器以及该硬件驱动器正确地取址以及存取。
摘要（英）：

One video encoding method includes: performing a first part of a video encoding operation by a software engine with instructions, wherein the first part of the video encoding operation comprises at least a motion estimation function; delivering a motion estimation result generated by the motion estimation function to a hardware engine; and performing a second part of the video encoding operation by the hardware engine. Another video encoding method includes: performing a first part of a video encoding operation by a software engine with instructions and a cache buffer; performing a second part of the video encoding operation by a hardware engine; performing data transfer between the software engine and the hardware engine through the cache buffer; and performing address synchronization to ensure that a same entry of the cache buffer is correctly addressed and accessed by both of the software engine and the hardware engine.
