摘　　要：复杂的测控应用对于实时性的要求非常高。在硬件已经确定的情况下,实时系统的性能很大程度上取决于所采用的实时操作系统。分析了QNX RTOS v6.1和VxWorks AE 1.1的特性,对这两个操作系统的实时性能指标进行了对比测试,测试结果表明,QNX RTOS v6.1的实时性能优于VxWorks AE 1.1。The complex application of measuring and controlling requires high performance of real-time. The performances of real-time operating system largely depend on the real-time operating system which you choose when the hardware is confirmed. The characteristics of QNX RTOS v6.1 and VxWorks AE 1.1 are systematically analyzed. The indications of real-time performance of these two operating systems are tested and compared. The results of tests show that VxWorks AE 1. 1＇s real-time performance is not match for QNX RTOS v6.1.
