Jaluna Ports Real-Time Linux Kernel to Texas Instruments Digital Media Processor for Network, Appliance and Terminals Applications

Combination of Real-time Multimedia with General Purpose Applications on a Single DM64x Processor to be Demonstrated at IBC in Amsterdam

Sep 9, 2004

AMSTERDAM (September 10, 2004) -- Building on the strength of the DSP-based TMS320DM64x digital media processor generation as the leading engine for networking and multimedia consumer products, Jaluna announced that it has ported its Linux software to the Texas Instruments Incorporated (TI) [NYSE:TXN] 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. This solution will be showcased on the TI booth (Hall 4 Stand 161) at IBC in Amsterdam from Sept 10-14, 2004.
"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 SA. "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 notes that, by allowing both Linux and DSP/BIOSTM to share the same DM64x media processor, Jaluna´s unique, innovative Jaluna/OSwareTM technology significantly reduces the bill-of-material without compromising functionality for IP-based consumer equipment such as set top boxes, video phones or digital recording surveillance systems. The IP set top box demonstration at the TI booth will show how a single DSP-based solution can achieve the following:

  • Using Linux for the ease and richness of application, communication layers, and GUI software components 
  • Using TI´s DSP/BIOS real-time kernel for handling all critical system tasks such as audio and video decoding, synchronization and rendering.

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 noted that its 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 
  • Linux root file system with standard Linux features, customized for embedded and MMU-less processors 
  • POSIX API and C library tailored to MMU-less and tiny memory footprint.

TI noted that, with performance of up to 4800 million instructions per second (MIPS) at a clock rate of 600 MHz, the DM642 device 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 standalone 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.
