Linux development platform targets multimedia SoCs

Dec 11, 2009 — by Eric Brown — from the LinuxDevices Archive — 13 views

Timesys announced that its LinuxLink embedded Linux development framework supports NetLogic Microsystems' MIPS32-based Alchemy Au1250 and Alchemy Au1300 system-on-chips (SoCs). The LinuxLink framework provides access to hundreds of open source Linux middleware packages, as well as automated development tools for processors used in mobile consumer electronics, says the company.

The power-efficient, MIPS32-based Au1250 and Au1300 SoCs were produced by Raza Microelectronics (RMI Corp.) before the company was acquired by NetLogic Microsystems earlier this year. They primarily target multi-function portable media players (PMPs), portable navigation devices (PNDs), mobile Internet devices (MIDs), and digital photo frames (DPFs), and both SoCs are available with Linux development support.

When announced in 2007 as the heir to the Au1200, the Au1250 was offered in versions clocked from 400MHz to 600MHz. The following year a 700MHz version was delivered. The Au1250 is notable for being the first MIPS SoC to be supported by the Android for MIPS platform developed by Mentor Graphics and MIPS Technologies.

In January of this year, a similar Au1300 family debuted in versions topping out at 800MHz, with plans to offer versions that clock up to 1GHz.

As usual with LinuxLink, customers receive hundreds of open source middleware packages, designed for developing "footprint-optimized Linux platforms with a rich set of APIs well matched to their end applications," says Timesys. Its online and desktop-hosted "Factory" build tools support the integration of third-party packages, custom applications, and proprietary software, with the desktop version offering more flexibility, says the company.

LinuxLink development tools include debugging tools, as well as the Eclipse-based TimeStorm IDE (integrated development environment). Documentation, tutorials, technical support, and professional services are also said to be available.

In November, Timesys followed up on its previous support for various MIPS32 cores by announcing LinuxLink support for MIPS Technologies' new M14K core and the M14Kc cores.

Stated Mike Wodopian, VP of marketing, Alchemy Processor products at NetLogic Microsystems, "We are delighted that Timesys has delivered a robust Linux development environment and professional services for our Alchemy Au1250 and Alchemy Au1300 platforms. The combination of Timesys' product, service and expert support makes them a valuable resource for our customers who want commercial support to complement their in-house capabilities and enable faster time to market."


The LinuxLink subscription for the the Au1250 and Au1300 processors is available now, says Timesys. For a limited time, developers can obtain free trial access to LinuxLink by registering here, and entering promotion code NETLAU1250.
