| 摘 要： | VME总线作为最早的国际通用开放式总线,已广泛应用到工业过程控制、军事应用等各个领域。但是由于VME总线的结构复杂,在开发基于VME总线的DSP工控系统中,DSP与VME总线的通信接口设计成为了瓶颈问题。为此,根据VME总线协议要求,采用FPGA完成了VME总线与DSP通信接口的IP核设计,并进行了电路板研制和通信功能的测试,实现了DSP处理器与VME总线的数据传输。

| Abstract: | As the first internationally applied open bus,VME bus has been widely used in the industrial process control field,the military field and many other fields.However,due to the complex structure of the VME bus,data transmission interface between DSP and VME bus has become a bottleneck problem in the development process of DSP industrial control system based on VME bus.Therefore,according to VME bus protocol,the IP cores of communication interface between the DSP and the VME bus based on FPGA is designed.At the same time,the circuit board is developed and the function of communications is tested and thus data transmission between DSP processors and VME bus is realized. |
