This dissertation represents the design and implementation of a test system based on PCI technology under QNX RTOS.For real time purpose, we developed the Test System under QNX.QNX is ideal for embedded real-time applications. It can be scaled to very small sizes and provides multitasking, threads, priority-driven preemptive scheduling, and fast context switching — all essential ingredients of an embedded real-time system. Moreover, QNX delivers these capabilities with a POSIX-standard API.Firstly, This the...
