Adreno

The Adreno series of graphics processing units (GPUs) are semiconductor intellectual property cores developed by Qualcomm and used in a variety of their SoCs. The core was initially developed under the Imageon brand name by ATI Technologies, which was acquired by AMD in 2006. After the buyout in January 2009,[1] Qualcomm renamed the Imageon products to Adreno.

Operating system support

There are proprietary drivers for the Linux-based mobile operating system Android available from Qualcomm themselves. There are no drivers available for any other Linux-based operating systems, but through libhybris, it became possible to use the Android drivers. Especially mer-based systems such as the Sailfish OS rely on this solution.

There is an ongoing endeavor of writing a Gallium3D-style graphics device drivers for the Adreno series of GPUs called freedreno.

As of September 2013, the kernel components (DRM and KMS driver) of freedreno have been accepted into mainline Linux kernel version 3.12.[16] These components are used together with user-space parts libDRM and Mesa 3D.

History

The Imageon (previously ATI Imageon) is a line of media processors developed by ATI providing graphics acceleration and other multimedia features for handheld devices such as mobile phones and Personal Digital Assistants (PDA).

Designed as system-on-a-chip (SoC), the Imageon line of media processors was introduced in 2002 to bring integrated graphics (from 2D in 2002 to 3D in latest products) to handheld devices, cellphones and tablet PCs.

The system-on-a-chip design incorporates an embedded CPU core, baseband sub-system CPU interface, memory controller, power management (ATI PowerPlay), internal RAM and stacked RAM with memory buffer, two display engines (for dual monitors on cellphones), imaging engine, image/video/audio capture engine, TV and audio output, dual digital signal processors for audio and video, and video acceleration engine.

The Imageon line was rebranded under AMD, after AMD acquired ATI in Q3 2006, as AMD Imageon, with official claims to have shipped nearly 250 million Imageon units to customers since 2003. However, as a result of company restructuring, AMD divested the handheld chipset business starting from the second quarter of 2008, thus the line is deemed officially discontinued.

At the end of 2008, the handheld branch was sold off to Qualcomm,[17] following an earlier sale of the Xilleon branch to Broadcom. AMD retained the Imageon name and will provide support for existing customers, although no future Imageon products will be introduced.[18]

Product line

Discontinued/Past generations

Current generation

Newest Brazilian Tectoy Console called Zeebo uses the ATI Imageon Chip to deliver fast and reliable graphics plus 3G access to download updates and new games for the console.

Announced in 2008 Mobile World Congress in Barcelona, AMD renews the Imageon line with the following products:

In addition to the application processor and the mobile TV solution chip, AMD also licenses several technologies to other firms and partners, such technologies include audio and graphics processors, as listed below:
