| Abstract: | 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. |
