基于MicroBlaze软处理器的无线定位算法验证平台的设计与实现

Wireless Location Algorithm Verifying Platform Based on MicroBlaze Soft Processor

随着移动通信技术的发展,基于移动通信系统的无线定位算法越来越吸引人们的关注。为了对该类算法进行实际验证,设计和实现硬件验证平台。该平台以Xilinx的Spartan XC3S1600E FPGA为核心,采用先进的MicroBlaze软处理器作为控制CPU,并与用Verilog语言描述的控制逻辑进行集成,充分展现了FPGA的强大功能。经过Matlab处理的发射数据可以通过USB接口下载到数据FLASH中,并且可以自由的进行更换,从而可以方便地验证不同的定位算法。该平台经初步实测,证明能够满足算法验证的要求。

With the development of mobile communication technology, the wireless location algorithm based on mobile com munication system begins to draw people＇s attention more and more. In order to verify such algorithm, a hardware verifying platform has been designed and implemented. Xilinx Spartan XC3S1600E FPGA is the kernel of such a platform,which adopts advanced MicroBlaze soft processor works as control CPU, it is integrated with control logic described by Verilog, and the power function of FPGA is brought forth. The transmitting data processed by Matlah can be downloaded into data FLASH via USB interface,and also can be changed freely. Therefore,variant location algorithm can be verified conveniently. The platform has been proved to reach the design requirement via testing elementarily.
