摘 要：Based on a solid analysis of the working principle of graphic processors, this paper puts forward the dual-rail handshake protocol of the data pipeline which is to be proved to improve the architecture of graphics rendering pipeline and thus make the system much closer to that of a graphic processor in real time. Specific algorithms and hardware design methods are as well developed in this work with their focus dwelling on the computation-consuming texture mappings, including two critical techniques: texture coordinate calculation and texture filtering. FPGA result shows that circuits based on textual algorithms can define accurately the textual coordinates and yield precise textual images, bringing significant improvements to the performance of graphics rendering.
