NIOSII for Sound Recording

Hi,

I am an amateur to NIOSII and have very thin knowledge with this features.

Hereby wish to have yours advise how can i start to develop a sound recording and play back system with NIOSII.

I wish to develop an embedded system that use for sound data analysis with Altera DE2. Microphone is attached to Mic port and the RS-232 is connected to laptop.

Other than that, i also wish to ask is it a better choice of using NIOSII rather than Verilog HDL for same purpose? Would it be hard to write the FFT code with Verilog HDL as i know that NIOSII work with C programming.

Do i need license to implement the NIOSII design on my board?

I do appreciate with more reference or link is provided for me to start the design work.

Many thanks!

    Hi,

    It has been a long time.

    But i tried to switch my project orientation as below. wish to have you advise again.

    I found that the DE2 has a demonstration, Karaok Machine... I m thinking to retrieve the sampled sound signal but i have no idea which of the variable indicated the sound data.

    I hope u have heard bout this demo program. As i m still desperate on getting the sound data for further analysis.

    Then, at the same time... i have done my algorithm in MATLAB simulink... Is it possible is put my Simulink in De2? The input of my simulink would be the retrieved sound data...

    Hope to have your advise again.
