摘要
With the rapid development of computer technology, Software-Defined Radio has become more and more popular. We can now transfer the communication system from hardware to software, which makes it more flexible and helps us virtualize the communication system. In this paper, we creatively introduce a method to guarantee hard real-time in user-space on Linux. Unlike the usual methods, Our method( real time with RDTSC) provides real-time feature by soft ware clock with RDTSC and isolating CPUs instead of interrupts from the hardware. Our method is highly lightweight and give the SDR systems more flexibility when compared to the usual methods with interrupts. The experiment and validation results show that real time with RDTSC has a significantperformance and can be used in physical communication systems
