摘　　要：为提高信号采集系统采样速度,增强系统可靠性,降低系统功耗,设计了一种基于TMS320VC5410和TLV1571的高速信号采集系统。通过TLV1571对模拟信号进行采样,然后经A/D转换后变换为数字信号,DSP通过定时中断每隔一段时间就读取一次采样数据并对数据进行处理。然后介绍这个系统的硬件电路各主要器件选择的原因、连接方法,实现方法及系统调试过程中应该注意的事项。实验结果表明这个系统完全能够满足采样速度在1.25 Mb/s信号的采集处理工作。在1.25 Mb/s的采样速度及10位采样精度条件下可以同时实现8路模拟信号的采样工作。In order to enhance the signal sampling rate and system reliability and to reduce system power consumption,a kind of high-speed signal acquisition system is designed based on TMS320VC5410 and TLV1571. Analog signal sampled by TLV1571 is converted to digital signal through the A/D. DSP reads the data waiting for being processed through the timer interrupt at regular intervals. The realization method and hardware connection of this system are described as well as some system debugging matters. Test result shows that this system is fully able to meet the general real-time signal acquisition and processing work with the sample rate of 1.25Mb/s. The sample of 8 road analog signal can be achieved coinstantaneous with the sample rate of 1.25Mb/s and the bit resolution of 10 bits.
