摘要
文中主要介绍了油水两相管流测量装置中数据采集模块的设计。此模块由MSP430F149单片机和TMS320VC5402DSP芯片构成双处理器系统,由单片机负责数据采集及与上位机通信,DSP负责相关运算以测量混合流体轴向相关速度,利用双口RAM实现两种处理器之间的数据共享与通信;并采用16位并行引导方式实现了DSP芯片的程序上电自举加载。整个系统设计简明,对DSP结合单片机的双处理器系统设计有一定的借鉴意义。
The double processor data acquisition system based on dual-port RAM is introduced in this paper. It is a double-kernel system composed of MSP430 single chip and TMS320VC5402 DSP, in which the single chip in charge of data acquisition and communication with the PC, the correlation algorithm is accomplished by the DSP. Dual-port RAM was used to communicate between single chip and DSP. The system has some values in the design of doublemicroprocessor system.
