OpenCL OpenGL DirectX implementation

I think on nVidia addresses of CUDA interface are used for all of them

So there should be some internal specs for AMD and Intel (i think Intel GMA and HD) too.
Does they have some special APIs or only addresses?
Where can I find address references for them?

I suggest you try enabling grammar checking rather than random word mode and then asking again.

Unfortunately, the most famous graphics card manufacturers do NOT release their specifications.
More information on that on the wiki article about Accelerated Graphics Cards

While Nvidia, who ranks third, doesn't release complete programming documentation, most of them do. For instance, AMD and Intel which rank first and second, respectively, do. And there are many others.
