本设计根据图5,在Xilinx ISE 14.7环境下搭建软件平台,采用Verilog HDL硬件描述语言完成编译综合,使用Modelsim SE 10.1c进行功能仿真验证,最后通过MATLAB R2012b对结果进行分析。 在Xilinx ISE中完成代码编写后,调用Modelsim进行软件仿真,当输入不同频率控制字,得到NCO产生的正余弦信号结果如图8所示。从图中可以看出,生成...
out in the FPGA. And on the basis of comparison of the different methods, CORDIC algorithm is realized by using pipelining structure design of IP core, makes the algorithm structure is simple, Suitable for hardware implementation. First of all, build the model in Matlab to test the feasibility...
This algorithm was implemented in hardware using Verilog and synthesized on the XILINX Zynq-7000 xc7z100ffv900-2 FPGA platform. Experimental results show that when the input angle bit width is 16, the operating frequency is 315.66 MHz and it only takes 6 clock cycles to ...
In software implementations CORDIC enables most of the code and data be shared between routines for trigonometric and hyperbolic functions, helping to conserve memory. CORDIC algorithm is often used to implement rotations needed in modulators and demodulators. CORDIC algorithm was introduced in 1959 by...
