The Mali and Immortalis series of graphics processing units (GPUs) and multimedia processors are semiconductor intellectual property cores produced by Arm Holdings for licensing in various ASIC designs by Arm partners.
Mali GPUs were developed by Falanx Microsystems A/S, which was a spin-off of a research project from the Norwegian University of Science and Technology. Arm Holdings acquired Falanx Microsystems A/S on June 23, 2006 and renamed the company to Arm Norway.{{Cite web|url=https://www.arm.com/company/news|title=News|website=Arm }}
It was originally named Malaik, but the team shortened the name to Mali, Serbo-Croatian for "small", which was thought to be fitting for a mobile GPU.{{cite web|url=https://community.arm.com/arm-community-blogs/b/graphics-gaming-and-vr-blog/posts/happy-10th-birthday-mali|title=Happy 10th Birthday Mali!|website=community.arm.com|publisher=Arm Limited|date=2016-06-17|accessdate=2021-12-19|author=Freddi Jeffries}}

= Technical details =
Like other embedded IP cores for 3D rendering acceleration, the Mali GPU does not include display controllers driving monitors, in contrast to common desktop video cards. Instead, the Mali ARM core is a pure 3D engine that renders graphics into memory and passes the rendered image over to another core to handle display.
ARM does, however, license display controller SIP cores independently of the Mali 3D accelerator SIP block, e.g. Mali DP500, DP550 and DP650.{{cite web |url=http://lkml.iu.edu/hypermail/linux/kernel/1604.0/00503.html |title=Initial support for ARM Mali Display Controller |publisher=Linux kernel mailing list |date=2016-04-01}}
ARM also supplies tools to help in authoring OpenGL ES shaders named Mali GPU Shader Development Studio and Mali GPU User Interface Engine.
Display controllers such as the ARM HDLCD display controller are available separately.{{Cite web | url=https://lwn.net/Articles/667575/ |title = DRM: Add support for the ARM HDLCD display controller [LWN.net]}}

Video processors
Mali Video is the name given to ARM Holdings' dedicated video decoding and video encoding ASIC. There are multiple versions implementing a number of video codecs, such as HEVC, VP9, H.264 and VP8. As with all ARM products, the Mali video processor is a semiconductor intellectual property core licensed to third parties for inclusion in their chips. Real time encode-decode capability is central to videotelephony. An interface to ARM's TrustZone technology is also built-in to enable digital rights management of copyrighted material.
= Mali-V500 =
The first version of a Mali Video processor was the V500, released in 2013 with the Mali-T622 GPU.{{cite news|last1=Lal Shimpi|first1=Anand|title=ARM MaliT622 V500 Video Block Complement Cortex A12|url=http://www.anandtech.com/show/7010/arm-malit622-v500-video-block-complement-cortex-a12|access-date=16 June 2016|publisher=Anandtech.com|date=2 June 2013}} The V500 is a multicore design, sporting 1–8 cores, with support for H.264 and a protected video path using ARM TrustZone. The 8 core version is sufficient for 4K video decode at 120 frames per second (fps). The V500 can encode VP8 and H.264, and decode H.264, H.263, MPEG4, MPEG2, VC-1/WMV, Real, VP8.
= Mali-V550 =
Released with the Mali-T800 GPU, ARM V550 video processors added both encode and decode HEVC support, 10-bit color depth, and technologies to further reduced power consumption.{{cite news|last1=Smith|first1=Ryan|title=ARM Announces Mali V550 Video Processor and Mali P550 Display Processor|url=http://www.anandtech.com/show/8650/arm-announces-maliv550-video-processor-malidp550-display-processor|access-date=16 June 2016|publisher=Anandtech.com|date=27 October 2014}} The V550 also included technology improvements to better handle latency and save bandwidth.{{cite news|last1=Sims|first1=Gary|title=Mali-T860 GPU headlines new range of integrated media designs from ARM|url=http://www.androidauthority.com/mali-t860-range-media-designs-543790/|access-date=24 June 2016|publisher=Android Authority|date=27 October 2014}} Again built around the idea of a scalable number of cores (1–8) the V550 could support between 1080p60 (1 core) to 4K120 (8 cores). The V550 supported HEVC Main, H.264, VP8, JPEG encode, and HEVC Main 10, HEVC Main, H.264, H.263, MPEG4, MPEG2, VC-1/WMV, Real, VP8, JPEG decode.

On January 21, 2012, Phoronix reported that Luc Verhaegen was driving a reverse-engineering attempt aimed at the Mali series of GPUs, specifically the Mali 200 and Mali 400 versions. The project was known as Lima and targeted support for OpenGL ES 2.0.{{Cite web|title=Announcing The Lima Open-Source GPU Driver|url=https://www.phoronix.com/news/MTA0OTQ| date=January 27, 2012| access-date=2023-01-15 |website=www.phoronix.com|language=en}} The reverse-engineering project was presented at FOSDEM, February 4, 2012,{{Cite web|title=An Open-Source, Reverse-Engineered Mali GPU Driver|url=https://www.phoronix.com/review/arm_mali_reverse| date=January 27, 2012| access-date=2023-01-15|website=www.phoronix.com|language=en}}[http://fosdem.org/2012/schedule/event/mali "Liberating ARM's Mali GPU"].
