The word-serial protocol with the message-based interface is implemented by EPLD and DSP . The GPIB functions are implemented by programming to the GPIB control chip . The transfer from VXI messages to GPIB functions is implemented by DSP .

通过EPLD和DSP实现了VXI总线的消息基接口 字 串行协议，通过DSP对GPIB控制芯片的编程实现了GPIB总线 各功能 子集，VXI消息到GPIB功能 子集的转换也通过DSP实现。
