Jaluna has ported its Linux software to the Texas Instruments DSP-based digital media processor

The result is a single DSP solution for IP set top box products, reducing manufacturers' design time and enabling a consumer-friendly end product. "With our innovative Linux support for TI's digital media processors, Jaluna is making it possible to bring high-end equipment functionality, services and applications to mid-range and low-end consumer products", said Michel Gien, President and CEO of Jaluna.

"The ability to use only one processor to run both Linux and real-time multimedia applications means significantly lower costs for designers and therefore a better choice for consumers".

Jaluna reckons that, by allowing both Linux and DSP/BIOS to share the same DM64x media processor, its novel Jaluna/OSware technology significantly reduces the bill of materials without compromising functionality for IP-based consumer equipment such as set top boxes, video phones or digital recording surveillance systems.

This solution gives designers and system developers new options that will allow them to combine the richness of Embedded Linux with the versatility and processing power of the DSP to rapidly bring fully DSP-driven devices to the market.

"Jaluna is offering great possibilities to DSP developers to leverage the power of embedded Linux", said Arnaud Duclap, DSP Business Development Manager for TI's video/imaging solutions in Europe.

"Embedded Linux is the perfect complement to the unparalleled media processing power and flexibility of the DM64x generation of DSPs, providing the application programming interfaces and device drivers of a system processor".

"Developers can now create IP set-top boxes both faster and at lower cost".

Jaluna/OSware allows the Linux and DSP/BIOS environments to run independently and concurrently from each other on the same media processor.

This avoids any GPL contamination of DSP/BIOS services, drivers and applications.

Jaluna's solution offers an open OS architecture designed to allow OEM products to evolve, and its native DSP/BIOS functionality means that it supports expressDSP-compatible multimedia codecs from TI's many third party vendors.

Linux features offered by Jaluna/OSware include: ucLinux 2.4.20 with standard real-time patches - Linux 2.6 will be available at the end of the year; a Linux root file system with standard Linux features, customised for embedded and MMU-less processors; and a Posix API and C library tailored to MMU-less and tiny memory footprint.

The DM642 offers cost-effective solutions to high-performance DSP programming challenges.

The DM642 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors.

Offered at a range of price-points and performance specifications, the DM64x generation as stand-alone system processors provide superior price/performance for device manufacturers.

The rapidly expanding Linux support for modern peripheral buses such as USB, ATA and PCI allows users to lessen the effort to maintain full connectivity to a rich set of peripherals.
