| 摘 要： | 为了降低基于DM642音视频驱动开发的复杂度,通过研究基于DM642的音视频编解码器驱动的开发方法,提出了基于DDK(Driver Developers Kit)的驱动开发模型,并举例给出基于DDK的音视频驱动开发流程。通过和传统的驱动开发模型相比,得出基于DDK的驱动模型使得驱动开发具有以下优点:重写的代码量更少;移植到不同的平台时,代码改动更少。

| Abstract: | To reduce the complexity of developing audio and video codec based on DM642.,a new method is proposed,and a example is given out for develop driver based on DDK(Driver Developer's Kit).Compared with traditional method for developing driver,the method to develop driver with DDK is proved to have these advantages:the amount of rewrite code is much less,the modification of the code is much less when plant to other platform. |
