i am using DE1 Board equipped with Cyclone II,im juz a newbie in FPGA, pls help me in this project.. i wound like to know how to perform the fast furior transform
You should solve it in the following order.1. Be familiar with your board and audio CODEC. 2. Write or get a module to drive the audio CODEC. Use it and understand it. 2. Choose between a pure hardware solution or a Nios II based solution. 3. If you have choosen a pure hardware solution there is a lot of stuff to study about fft implementation: Altera core, own core, open core. 4. If you have choosen a Nios II based solution you must connect your audio CODEC module as an slave peripheral. Internet is full of C language based FFT implementations.

You could try looking this two tutorials,http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf (http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf) http://www.nioswiki.com/@api/deki/files/7/=my_first_nios2_software_tutorial_v72.pdf (http://www.nioswiki.com/@api/deki/files/7/=my_first_nios2_software_tutorial_v72.pdf) Nevertheless, here http://www.altera.com/literature/lit-nio2.jsp (http://www.altera.com/literature/lit-nio2.jsp) you will find all Nios II Stuff.

Cheers, - Brendan --- Quote End --- i have the sample already, i juz wonder which component is required to add in whn i configurete in SOPC builder, i tried rs233 communication in NIOS already , i add a Jtag uart rs232, memory and processor, can anyone tell me which component is the audio codec which i suppose to add
You could use example module included in example suggested by Brendan, another option is the Altera University Program cores:ftp://ftp.altera.com/up/pub/university_program_ip_cores/80/audio.pdf ftp://ftp.altera.com/up/pub/university_program_ip_cores/80/audio.zip
