摘要
设计了以FPGA为核心处理器的高速多路数据采集系统,整个数据采集系统可实现48路最大工作频率为20kHz的信号采集任务。在该系统中,还采用了TI公司最新推出的高速低功耗A/D芯片THS1206从而大大降低了系统功耗。另外,采用了ATMEL公司的AT89C2051实现采集器与PC机的串行通信控制。
A High-speed multi-channel data sampling system has been designed with FPGA as its kernel processor.The system can sample20kHz and48channels analog signal.THS1206,which is one kind of low-cost power and high speed A/D chips pro-duced by TI Co.,has been used in the system.The serial communication with PC is completed by using AT89C2051produced by ATMEL Co..
