【摘要】 DSP系统是一种新型的快速数字处理系统,它处理的必须是数字信号,这就需要通过前向通道和后向通道使DSP芯片能用于实际系统,模数转换差不多是DSP的必需的外围电路.介绍了高性能定点DSP芯片TMS320VC5402和ADC芯片AD1674的主要特点,设计了基于TMS320VC5402与AD1674的接口电路并利用C语言进行了硬件程序设计.更多还原

【Abstract】 The DSP system is a new,fast digital process system in which the input must be digital signals.Hence the AD converter is the necessary peripheral circuit to make DSP chip be used in practical system through forward and backward channels. The main characteristics of high-performance fixed-point chip TMS320VC5402 and Analog-to-Digital Converter AD1674 are introduced. The interface circuit and applied software based on AD1674 and TMS320VC5402 were designed with C language.更多还原
