Jie Gao, Liang Wang, Min Jing

Abstract

This paper presented a multi-channel audio signal processing platform based on TMS320VC5509A. It introduced the system basic circuit and the hardware interface design of TLV320AIC23B and TMS320VC5509A. The platform can achieve input four-channel signal and output four-channel simultaneously. Due to its low power consumption, high performance and portable feature, the platform has been used in the system of noise reduction headphone.
