[Mp4-tech] H264 Transform and Quantization

[Kostas Babionitakis]

Hello to all,
I have studied the H264 Standard and i want to implement the Encoder 
Transform module in hardware. I've found out that two types of 
transformation are used; DCT and Hadamard. Is there any sample code for 
the two transforms or any JVT documents regarding a hardware 
implementation? Even a software implementation could help me out.
I have many questions regarding the way the data input is handled and 
how the matrix multiplications are implemented. My guess is that a 
butterfly operation can be used but i am not sure of that. Is that right 
or a different technique is more efficient?
Thanks in advance for any response
