Design of PCI Bus General 6-axis Motion Controller Based on DSP

In this article,to carry the 6-axis motion controller out,a method of using PCI special interface chip PCI9052 to be a interface bridge of PCI bus and DSP(TMS320LF2407),was introduced.Firstly,the whole hardware structure of the controller was given,including the interface specification of PCI bus,local bus interface circuit,DSP expander.Secondly,the collocation method of the board was introduced,thus the configuration of address rage register,base register and chip selection control register was involved.Finally,this article presented the design method of the driver program.Throughthis method of combining PCI and DSP,we can carry out the fast communication between controller and upper controller and take the full advantage of the DSP's features of high-speed and powerful.
