my task is to implement a code generator for a compiler written in ANSI-C for a new math language and to provide a run time environment for it under Windows 7-64. I have problems to find technical documents on the Radeon 7 GPU apart from the instruction set manual. There must be low level drivers somewhere to move code and data to the GPU, to start execution, and to retrieve results after some handskaking. Catalyst seems to only support older GPUs. Can anybody give me a hint where to find such drivers and appropriate documantation, or some suggestions on how to proceed?
