Abstract: Aiming at the enhancement of the complexity of control arithmetic and the limited disposal ability of embedded industry controller, this paper brings forward the design of fast control system, which is based on Digital Signal Processor(DSP) and PMC bus, including the instauration of a general and standard hardware platform mainly with DSP, dual-port RAM, PCI bridge and CPLD chips, and the design of the device driver of PMC bus on VxWorks operating system. Parallel disposal system based on DSP and embedded industry controller is proved to be able to realize complex control arithmetic and digital process method, which can improve real time performance and precision of whole system effectively.

Key words: Digital Signal Processor(DSP), PMC bus, fast control system, VxWorks operating system
