The i.MX range is a family of Freescale Semiconductor proprietary microprocessors for multimedia applications based on the ARM architecture and focused on low-power consumption. The i.MX application processors are SoCs (System-on-Chip), that integrate many processing units into one die, like the main CPU, a video processing unit and a graphics processing unit for instance. The i.MX products are qualified for automotive, industrial and consumer markets. Most of them are guaranteed for a lifetime of 10 to 15 years.[1]
Many devices use i.MX processors, such as Ford Sync, Amazon Kindle, Sony Reader, some Logitech Harmony remote controls and Squeezebox radio, some Toshiba Gigabeat mp4 players. The i.MX range was previously known as the "DragonBall MX" family, the fifth generation of DragonBall microcontrollers. i.MX originally stood for "innovative Multimedia eXtension".

Software solutions

Freescale proposes a layered approach of software with selection of software components optimized for its chips. The i.MX board support packages (BSP), common across all i.MX nodes, consists of kernel optimization, hardware drivers and unit tests. The company also provides a portfolio of multimedia Codecs (ARM and Video processing unit accelerated). The i.MX solution also includes middleware with reuse of open source frameworks like multimedia framework plugins, power management, security/DRM or graphics (OpenGL/OpenVG).

All software solutions for i.MX are publicly available on the company website.

Linux

Freescale i.MX development kits include a Linux software stack with a GNOME Mobile environment.

On the i.MX51 family, the reference user interface is Ubuntu. The last Ubuntu version supported is 10.04.1 (still available on mirrors). Ubuntu dropped the "official" i.MX51 family support since version 10.10.[2] Since Ubuntu 11.10 support for the i.MX53 Quickstart board is available as a preinstalled desktop or server SD card.[3]

The OpenEmbedded Linux distribution supports several i.MX platforms.

Commercial Linux support is available from companies like Lanedo, TimeSys, MontaVista, Wind River Systems and Mentor Graphics.

Support for the Freescale i.MX51 was added to FreeBSD on 2013-10-31. [4] Support for other members of the i.MX5 family has been added since.

Support for the Freescale i.MX6 family was added to FreeBSD on 2013-10-31.[5]

OpenBSD

Support for the FreeScale's i.MX6 series SoC was added to [6]OpenBSD's head on the 2013-09-06.

Windows CE

Freescale i.MX development kits include WinCE.

Android

In February 2010, Freescale launched an Android platform for the i.MX5x family.[7]

Chromium

In early 2010 Freescale demoed Chromium OS running on the i.MX515 processor.[8] The company has not disclosed any further plans about Chromium or Chrome.

Real-time OS

Freescale has a range of partners providing real-time operating systems and software solutions running on the i.MX processors, such as Trinity Convergence, Adeneo, Thundersoft, Intrinsyc, Wind River Systems, QNX, Green Hills and Mentor Graphics.[9]

Reference designs

In January 2010, Freescale announced the first platform of its Smart Application Blueprint for Rapid Engineering (SABRE) series.[10] It is a smartbook (tablet form factor with 7" touch screen resistive), running on i.MX515.

In February 2010, Freescale demoed the SABRE platform for eReaders,[11] based on i.MX515.

Many more reference boards are mentioned and supported through the Freescale i.MX community website. These include:

  • i.MX23EVK
  • i.MX25PDK
  • i.MX28EVK
