Mali 是一款由ARM Holdings(ARM,安谋科技)研发设计的移动显示芯片组(GPUs)系列。该显示芯片组的电路设计和架构研发完全由ARM自主设计,ARM特别设立了ARM Norway(ARM挪威)显示处理事业部来负责研发设计ARM Mali显示芯片系列,该部门的前身是Falanx。
Mali显示技术细节
[编辑]和其他基于IP核心(IP cores)嵌入式技术的3D显示芯片一样,Mali显示芯片组没有提供特别用来驱动LCD显示器显示图像的显示控制器(类似于显卡),相反地,它是一个纯3D显示引擎,它将图像载入到缓存中,并且由专门负责图像显示处理的内置显示核心来显示这些图像。
其内置的那些不同渲染API,例如OpenGL ES、OpenVG等等,都实现了shader图像处理程序。ARM还提供了开发工具用来进行针对其显示芯片的处理,如Mali GPU Shader Development Studio和Mali GPU User Interface Engine。
型号
[编辑]Mali显示芯片组改进自Falanx公司研发生产的显示技术芯片组,目前Mali显示芯片组有如下型号:

Lima FOSS 驱动
[编辑]2012年1月21日,Phoronix报道称Codethink最主要的开源显示技术开发商:Luc Verhaegen已经开始尝试为Mali显示芯片组系列提供技术支持,特别是Mali 200 以及 Mali 400 型号。该项目称为Lima(利马)并且开始提供对OpenGL ES 2.0的全面支持。[26]
FOSDEM已于2012年2月4日提供主要支持,[27][28] 并且提供了 limadriver.org[永久失效連結] 网站用于展示新的研发进展。
2013年2月2的Verhaegen展示「雷神之锤III竞技场」timedemo模式,于利马驱动上运行。[29]
