摘要
提出一种基于SOPC技术的嵌入式数字音频的自动增益控制系统解决方案,移植实时操作系统μC/OS-Ⅱ作为嵌入式应用软件运行平台,通过采用一种多参数融合的AGC算法进行实时AGC处理,设计并实现了应用于数字演播室中,具有一定噪音抑制能力的嵌入式数字音频AGC系统。
This paper presents the implementation of embedded digital audio AGC system based on SOPC with the transplant of the real time operating system RTOS μC/OS-Ⅱ as the running platform of the embedded application software.By adopting a multi-parameter AGC method,AGC is real-time processed.The embedded digital audio AGC system with noise restrain ability that can find application in digital studio is designed and implemented.
