Mali (GPU)

From Wikipedia, the free encyclopedia

The Mali series of graphics processing units (GPUs) are semiconductor intellectual property cores produced by ARM Holdings for licensing in various ASIC designs by ARM partners.

The GPU cores are mainly developed by ARM Norway, at the former Falanx company site.

Technical details[edit]

Like other embedded IP cores for 3D support, the Mali GPU does not feature display controllers driving monitors (such as the combination often found in common video cards).

Instead the Mali ARM core is a pure 3D engine that renders graphics into memory and hands the rendered image over to another core that handles the display.

ARM supplies tools to help in authoring OpenGL ES shaders named Mali GPU Shader Development Studio and Mali GPU User Interface Engine.

Variants[edit]

The Mali core grew out of the cores previously produced by Falanx and currently constitute:

Some Malis support cache coherency for the L2 cache with the CPU.[8][9]

The Lima FOSS driver[edit]

On January 21, 2012, Phoronix reported that Luc Verhaegen is driving a reverse-engineering attempt aimed at the Mali series of GPUs, specifically the Mali 200 and Mali 400 versions. The project will be known as Lima and support OpenGL ES 2.0.[35] The reverse-engineering project was presented at FOSDEM, February 4, 2012,[36][37] followed by the opening of a website demonstrating some renders. On February 2, 2013, Verhaegen demonstrated Quake III Arena in timedemo mode, running on top of the Lima driver.[38]
