[VHDL-FPGA-Verilog] High-Speed-FFT

Description: 优秀硕士论文，课题采用现场可编程门阵列((FPGA)，设计实现了一种超高速FFT处理器。目前，使用FPGA实现FFT多采用基2和基4结构，随着FPGA规模的不断扩大，使采用更高基数实现FFT变换成为可能。本课题就是采用Alter的Stratix II芯片完成了基16-FFT处理器的设计。在设计实现过程中，以基2-FFT搭建基16-FFT的运算核，合理安排时序，解决了碟形运算、数据传输和存储操作协调一致的问题。由于采用流水线工作方式，使整个系统的数据交换和处理速度得以很大提高。本设计实现了4096点和256点的变换，两个内部运算时钟都可以达到1 OOMHz以上，其中256点变换的数据吞吐率高达1.36GHz -a design of ultra high speed FFT processor based onFPGA is developed in this paper. At present we always use radix-2 and radix-4 tocarry out FFT. When the scale of FPGA is panding,it s possible to implement higher radix FFT. This topic uses Stratix II of Altera company to carry out a processor of radix一16 FFT.In this design, radix-16 FFT is carried out by radix-2FFT, The design uses rational time sequence arrangement to make butterflycomputing,data transformation and memory coincide.In order to avoid the bottleneck,pipeline pattern is used,this method acceletates the operating.Thescheme realizes the 4096-points and 256-points FFT, their operation clocks canboth reach above 100MHz. Among them ,the throughput of 256-points FFT is up to1.36GHz.
