Abstract Based on the design of PMC-Sirra 7364 card device driver under Solaris 8 of UNIX system, the development technology of PCI device driver under UNIX system is discussed. It presents the idea of design, basic programming procedure, program structural framework, some useful functions and the system management commands. This method can be further applied to the development of CompactPCI device driver under UNIX, which provides a new approach to replacing PC industrial control computer with UNIX host to implement telecommunication and control devices with high stability and reliability.
Key words UNIX system; PCI; solaris; device driver
