Pointers and hardware Innovation in CUDA

Hello,

I read in an article that the basic innovation in CUDA is the support for pointer. My question is what changes are made in the hardware of the previous GPUs for providing the support for pointers? Also what hardware changes made the support for C language?

Thanks in advance

Where did u read such a thing?

CUDA definitely has a lot of great things to be talked about… but pointers…? uh…

I think he means global memory being addressable by pointer arithmetic instead of using samplers or preset per-pixel accesses.

I think he might be referring to this interview:

Big_Mac you got it right!! What are the hardware changes made after the introduction of these features?
