摘　　要：DSP(数字信号处理器)具有强大的数字信号处理能力,在其应用系统中,大多由ADC和DAC通道来完成对模拟信号的数字化处理。本文介绍了一种集成ADC和DAC于一体的TLC320AD50C模拟接口电路与TMS320VC5416定点DSP接口电路的硬件设计方法,并结合一个具体的软件实例说明主从模式下软件的实现方法。DSP （digital signal processor） the digital signal with power deals with ability , in its application system, mostly finished the digitized processing of the analog signal by ADC and DAC passway. This text has introduced a kind of integrated ADC and DAC in integrative TLC320AD50C simulation interface circuit and TMS320VC5416 fixed DSP interface circuit hardware design method, combine one concrete software instance prove principal and subordinate implementation method of software under the mode.
