“…Compared with architectures presented in [8][9][10], the Clipping Unit in this paper has the following advantages: Firstly, it employs a full clipping pipeline which does not require later clipping. Secondly, the Clipping Unit does not require the input vertices in a specific form like triangle strips.…”

“…The architecture in [8] takes advantage of input triangle strips combined with a modified clipping algorithm to eliminate the overhead of taking an entirely new triangle. The proposed architecture in [9] does clipping in only two planes: the front and back z plane. The remaining clipping will be done in rasterization.…”

This paper focuses on the implementation of vertex transformation and triangle clipping in the field of 3D acceleration. A dedicated matrix accumulating architecture is proposed to multiply transformation matrices and generate an accumulated transformation matrix. Then the accumulated transformation matrix is used for per vertex transformation. A combined clipping algorithm of Cohen-Sutherland and Sutherland-Hodgeman is adopted to accelerate triangle clipping. In addition, the clipping process is pipelined in order to increase the throughput. Experimental results show that our implementation can reach more than 25% performance higher than traditional method.
