Nobody can give a reasonable answer to such a poorly formulated question.
You refer to what project? Link? You refer to what MATLAB program? Link? What exactly is the input vector which produces differing output vectors? Why do they differ? And, surprise, you have solved the problem yourself... Hellwig |

thank you very much for your replay.
i implement cfft project from opencores and the project link is http://opencores.org/project,cfft the input is a vector of 1024 binary points (data width is 12 bits) that i read it from text file using vhdl testbench when i compare the output of this project with fft function of matlab using the same input text file, There is a lot of difference in the results. forgive me for my poor English. I ready for any further clarification. |
