摘要
利用嵌入在Xilinx FPGA中的PowerPC技术,采用嵌入式可编程片上系统的设计思想,设计了基于现场可编程门阵列(FPGA)的控制器,实现在FPGA中定制完整的实时信号处理设备,方便了信号处理的设计。文中设计的控制器完成对快速傅里叶变换(FFT)、先进先出(FIFO)等模块的各控制信号的控制及对数据收发的控制。通过在总线上挂接自定义IP,增强了片上微机功能,使得设计更具灵活性。通过编制特定的软件代码,利用PowerPC的架构可以方便地控制FFT模块的处理点数。最后对该控制器进行了仿真,并在XUP VirtexⅡ pro实验板上对其功能进行了具体的实现。
This paper uses the PowerPC technique embedded in Xilinx field-programmable gate array （FPGA） and the design idea of embedded system on programmable chip （SOPC） to design the controller based on FPGA,which implements to customize the whole real-time signal processing device in FPGA and facilitates the design of signal processing. The controller designed in this paper acco/nplishes the control to each control signal of fast Fourier transform（FFT） model,first in first out（FIFO） model,etc, and the control to the data receiving and transmission. The function of the microcomputer on chip is strengthened by connecting the custom IP in the bus, which makes the design more flexible. The quantity of management points of FFT model can be conveniently controlled through programming the special software codes by using the structure of PowerPC. Final- ly, this paper simulates the controller, and concretely realizes the function on the XUP Virtex Ⅱ pro test board.
