a hardware algorithm for graphics rasterizer on embedded platform is presented. By dividing the pixels in the triangles bounding box into a number of regular tiles
the algorithm do the scan conversion
pixel interpolation and projective correction on the basis of tile architecture. After a lot of optimization
the algorithm is implemented and tested on FPGA. As compared with the traditional algorithm
the algorithm presented in this paper has increased the pixel hit rate
and reduced the computational complexity
as well as effectively reduced the hardware cost. Testing results show that
the quality of the algorithms rendered images has reached the level of OpenGLES 1.1.In general scene
the rendering speed reached 30 fps
meeting the requirements of real-time rendering. In terms of the synthesized hardware resources
it is small within 5 545 slices on Xilinx FPGA Vertex2P xc2vp30-7ff89.
