摘　　要：设计一款测井数据采集板卡,用来处理单芯曼彻斯特编码测井仪器信号。板卡以TI公司TMS320C6745芯片为核心,利用DSP强大的数字信号处理能力,实现曼彻斯特编码信号的采集和解码,在DSP/BIOS实时操作系统下,移植NDK实现Ethernet接口。This paper designed a well-logging data acquisition board which used to process the Manchester code signals of single conductor logging tools. The board utilized the powerful processing ability of TMS320C6745 to acquire and decode the Manchester signals, and implemented the Ethernet interface through transplantation of NDK under the real time operating system DSP/BIOS.
