GSM接收机数据的快速传输

GSM receiver fast transfer of data

以软件无线电接收机中的GSM接收机为例,采用TMS320C6713 DSP处理器,基于McBSP(多通道缓冲串行口)和EDMA(增强型直接存储器访问)实现DSP和外设的数据传输,传输过程因无需CPU干预,故可提高数据传输、处理的速度,保证实时性。实验结果表明,通过灵活控制EDMA,不仅能够提高数据的传输效率,而且能够充分发挥DSP的高速性能。这种信号传输方法通用性强,可广泛应用于其他数据传输和信号处理领域。

For GSM receiver,the TMS320C6713 DSP processor is used to achieve data transmission between DSP and peripherals,which is based on McBSP（Multi-channel Buffered Serial Port） and EDMA（Enhanced Direct Memory Access）.The experimental results show that,the efficiency of data transmission would be improved and the high speed performance of DSP would be put into full play.This transmission method can be widely applied to other data transmission and signal processing.
