利用TMS320 VC33自带同步串口实现双DSP无缝连接

Realization of seamless connection between double DSP by using TMS320VC33 synchronized serial port

以基于TMS320VC33 DSP开发的光纤陀螺SINS/GPS组合导航系统板为模型,介绍了TMS320VC33同步串口的原理,对串口的各个存储器映射寄存器进行了正确的设置,并利用定时器发送数据,成功实现双VC33之间的无缝连接,为SINS/GPS组合导航的数据传输提供了快速可靠的硬件保证.

With the fiber optic gyroscope SINS/GPS integrated navigation system board using TMS320VC33 DSP as model, the article introduces the principles of TMS320VC33 synchronized serial port. The proper configuration is made to memory-mapped registers of the ports. The timer is used to transmit data. The seamless connection between double DSPs is realized successfully, which provides quick and reliable hardware guarantee for the data transmission of SINS/GPS integrated navigation.
