摘要
利用高速的数字信号处理器(Digital Signal Processing,简称DSP)TMS320VC33(以下简称VC33)丰富的软件和硬件资源以及TDC-GP2(以下简称GP2)灵活的可编程的特点,设计了一种测量流量和温度的电路。其主要有三部分组成:一是测量温度、流量的电路,核心器件就是GP2;二是与计算机的通信电路,利用串行接口芯片实现电平的转换;三是测量数据的处理电路,以VC33为电路的核心。系统电路通过采用小型封装的芯片以及低频芯片,使系统的总功耗很低。
The system of measure flow and temperature is designed by high speed dsp-TMS320VC33,which has very abundant software and hardware resource,and TDC-GP2,which has flexible programmability.The system has three parts:The first part is the circuit of measure flow and temperature,and in this part,GP2 is the most important.The second part is circuit of communication with computer by serial interface.The third part is measure data processing circuit.The system has very low power waste.Because the chips of system have little package and low work frequency.
