摘要
TD-LTE系统中,为了满足对算法处理速度的要求,采用了基于DSP+FPGA的硬件平台实现方案。方案中DSP芯片配置FPGA,由FPGA实现系统的时序控制,而TD-LTE系统中算法由DSP与FPGA共同实现,可以充分发挥两种芯片的优势,达到系统性能的最优化。为解决DSP与FPGA之间高速数据通信,基于TMS6455系列DSP芯片与Virtex6系列FPGA芯片,设计了一种DSP与FPGA进行双向数据通信的方案。板级联合调试的结果表明,该方案具有较高的可行性和通用性。
In order to satisfy the requirement of high operation speed in TD-LTE RF conformance testing instrument,the DSP＋FPGA scheme is used.In the scheme,DSP is used to configure the FPGA module,and the FPGA is used to control the timing of system.The algorithms in the TD-LTE system are completed by both of the chips.This strategy will play on strengths of the chips,which make the system to achieve the optimal performance.In order to carry out the two-way communications between DSP and FPGA,a simple and effective solution which is based on TMS6455 series DSP and Virtex6 series FPGA is proposed.Board level FPGA and DSP joint debugging has proved that the scheme can not only realize communication between FPGA and DSP,but also have high robustness and stability.
