Back in January there was the release of the R600/700 3D documentation
that is being used along with some open-source code
to begin powering up the Radeon HD 2000/3000/4000 hardware with OpenGL acceleration support in Mesa. Some of this code should be out soon
, but this past week AMD has released some more NDA-free documentation. This time the documentation concerns the R700 Instruction Set Architecture (ISA).
In June of last year, AMD had released the R600 Instruction Set Architecture
. In this new R700 ISA documentation is 392 pages worth of information on various topics, particularly about the Stream processing abilities of the R700 family.
