摘　　要：在通用处理器上进行信号处理是软件无线电发展的方向之一,现有的共享存储并行编程(Open MP)和直接线程并行法难以对信号处理进行并行加速。针对串行算法的并行化问题,引入多核流水线方法,对传统串行方法和多核流水线的实时性进行了分析对比。针对多核流水线的同步问题,研究了一种分布式的自适应线程同步方法。结合信号处理实例,对串行方法和多核流水线的实时性进行测试,结果表明多核流水线的吞吐率是串行方法的2.1倍,处理能力大大提高。Signal processing on general purpose processor is one of the directions of software radio development.Open multi-processing（Open MP） and the direct thread parallel method have difficulty in parallel acceleration of signal processing.Aiming at the parallelization of the serial algorithm,the multi-core pipeline is introduced,and the real-time performance of the traditional serial method and the multi-core pipeline are analyzed and compared.Aiming at the synchronization problem of multi-core pipeline,a distributed adaptive thread synchronization method is studied. Combined with the signal processing example,the real-time performance of serial method and multi-core pipeline is tested and results show that throughput rate of multi-core pipeline is 2.1 times that of serial method,so the processing power is greatly improved.
