The BrookGPU compilation and runtime architecture consists of a two components. BRCC is the BrookGPU compiler is a source to source metacompiler which translates Brook source files (.br) into .cpp files. The compiler converts Brook primatives into legal C++ syntax with the help of the BRT, Brook RunTime library.

The BRT is an architecture independent software layer which implements the backend support of the Brook primatives for particular hardware. The BRT is a class library which presents a generic interface for the compiler to use. The implementation of the class methods are customized for each hardware supported by the system. The backend implementation is choosen at runtime based on the hardware available on the system or at request of the user. The backends include: DirectX9, OpenGL ARB, NVIDIA NV3x, and C++ reference.
