DWT on NIOS

Hi,

I am trying to implement 2D-DWT on a Nios II processor

I am able to decide on the Hardware part......

But I am not able to decide on how to write the software code for implementing the application....

Can anyone help me in this regard....

Either in the form of tutorials or sample codes.....

With Regards

Sivam

    2D DWT is a classic example of something that you should implement in hardware (pure hardware, or a co-processor) and not in software.

    Why do you want to do it in software ?

    I will be happy if you could please guide me in this regard as i am new to NIOS......

    1st. Program a 2D DWT processing block in hardware (I already did this and even published it, just google for "Amilcar Lucas flexwafe").

    2nd. Write a program for Nios to control a DMA engine that pups image data thru the 2D DWT blocks.
