基于有限状态机的视频编解码器设计

Design of Video Coder Based on Finite State Machine

在实时嵌入式多媒体通信系统中,分析了基于帧的视频编解码器设计方式对语音编解码器、通信模块实时性的影响,利用状态转换图分析了视频编解码器的有限状态机(FSM)。实验结果表明,基于状态机的设计方法提高了嵌入式系统的实时性。

This paper analyzes how the frame based video codec structure undermines the real-time performance of audio codec and communication module in embedded multimedia communication platform, and proposes a design solution based on finite state machine（FSM） using state converting graph. The experimental results demonstrate that the FSM control flow improves the system real-time performance obviously.
