Abstract: With the rapid development of VLSI and graphics technology, especially the rapid development of 2D/3D graphics acceleration technology, GPU graphics acceleration has become the main issue of research. This paper designs the driver of light weight DirectFB graphics hardware acceleration system on FT. This paper, from the design and implementation of GPU graphics acceleration perspectives, introduces Radeon GPU graphics acceleration related principles and mainly researches GPU memory address space and command transport mechanism and others base technology implement. At last, this system is implemented.

Key words: DirectFB, Radeon GPU, graphics acceleration, GPU memory address space, command transport mechanism
