摘要
介绍了一种采用DSP的同步串口和并行外设接口,对I2S标准音频数据和ITU-R 656格式数字视频信号进行处理的方法.在此基础上,提出了系统的总体设计方案.通过系统样机的硬件与软件调试,实践结果表明,在音乐播放和数字监控中,设计的系统完全满足各项功能参数.
This paper presents a method of the I2S standard audio data and ITU-R 656 format digital video signal processing through synchronous serial port and parallel peripheral interface in DSP.And the total designing project of system is discussed.The hardware and software debugging have been completed all right.The measure is applied to music playing and security monitoring,and some experimental data are acquired.The results show that the platform is satisfied with all kinds of function parameters.
