摘要： Disclosed is an apparatus and method for generating a lighting value based on a number of lighting factors. A lighting accelerator first converts an ambient portion, a diffuse light portion, and a specular light portion of the lighting factors into the log domain. Then, data combination units operate on the lighting factors after they have been converted. Then, the lighting factors are converted back from the log domain using anti-log processing. Converting the lighting factors into the log domain is accomplished by using a series of linear equations using coefficients that are all based on powers of two, and are therefore easily calculable. Further, while in the log domain, the specular light portion of the lighting factor is operated on by a special purpose multiplier that uses a truncated partial product tree, saving area and power with only a negligible amount of error.

摘要翻译： 公开了一种基于多个照明因素产生照明值的装置和方法。 照明加速器首先将照明因素的环境部分，漫射光部分和镜面光部分转换成对数域。 然后，数据组合单元在转换后对照明因素进行操作。 然后，使用反日志处理将照明因素从日志域转换回来。 将照明因子转换为对数域是通过使用一系列线性方程来实现的，这些方程全部基于二次幂，因此易于计算。 此外，在对数域中，照明因子的镜面光部分由专用乘法器操作，该专用乘法器使用截断的部分乘积树，仅以可忽略的误差量来节省面积和功率。
