摘要
三角形光栅化是图形处理器的关键环节。文中光栅化算法通过精确控制扫描边界,同时利用重心坐标计算属性值,过程中采用迭代的方式计算,极大地降低了运算量。文中经过System C系统建模验证,同时又利用Verilog进行硬件电路设计,然后通过硬件测试平台完成功能测试。测试结果表明完成了三角形光栅化基本功能,提高三角形光栅化速度,同时降低硬件资源的使用量和功耗。
Triangle rasterization is a key part ol the graphics processor. In this paper, the rasterization algorithm is used to control the scanning boundary accurately, and the attribute value is calculated by the coordinates ol the center ol gravity. The iterative method is used to calculate the value. The paper modeled and verified by SystemC system,and then uses Verilog to design the hardware c irc u it,and then completes the functional test through the hardware test platform. The test results show that the basic functions ol triangular rasterization are completed,and the triangular rasterization speed is improved,and the hardware resource usage and power consumption are reduced.
