The Interface Design of the Voice System Based on the TLV320AIC23 and CPLD

Abstract:

With the development of new technology, there is a lot of break-through in the systematic field of the language learning in recent several years. Digitized voice system is the representative of the new products. The function, interrelated registers and audio sampling rates of the TLV320AIC23 are introduced. The interface design, which is used CPLD to replace DSP, is put forward by analyzing. The design realizes the transition of A/D、D/A in the device digital voice system. The approach makes the system more compacted, more steadied and cheaper. And those characteristics give our design more competitive in the market. Furthermore, the most important is that we own the intellectual property of the design.
