Design and implementation of geometric transformation in graphic accelerator
图形加速器中几何变换的设计与实现*

Geometric transformation Unit(rotation, translation, scaling) is the only basic unit which performance animation of graphics, and the it play a crucial role in performance of graphics accelerators.This paper show its Software design model and it adopts the parallel pipeline structure, designed and implemented the geometrical transformation unit with hardware. And it improve the speed of graphics accelerators. The hardware is implemented in FPGA and demonstrated excellent performance. The experiment shows that the circuit can achieve its function, and it will show the better performance when it need deal with a large-scale data.
