Embedded Linux SDK supports TI ARM+DSP dual-core chips

Feb 1, 2001 — by LinuxDevices Staff — from the LinuxDevices Archive — views

New York; LinuxWorld — (press release excerpt) — RidgeRun, Inc. announced today that it is partnering with DevelopOnline to offer RidgeRun's DSPLinux SDK, based on Texas Instruments' TMS320DSC21 digital signal processor (DSP), through DevelopOnline's Web-based open platform development site. The platform, to be fully online by April, will give developers easy access to the complete DSPLinux simulation and hardware environment via DevelopOnline. Now leading digital camera and other Internet appliance manufacturers can leverage the performance of TI's DSP technology and shorten time to market by capitalizing on the depth of Linux-based applications.

DSPLinux is optimized for multimedia applications in which DSP's offer tremendous processing power with very low battery consumption. DSPLinux is focused on dual-core ARM+DSP architectures, with its Linux kernel residing on the ARM processor to control the operation of the DSP. DSPLinux provides a powerful Open Source API, its Open Multimedia Interface (OMI), to give access to the multimedia power of the DSP to any Linux programmer without requiring DSP algorithm development. Furthermore, DSPLinux includes powerful proprietary features such as memory compression, power management, and the DSPLinux Bridge, which controls the resources of the DSP.

The DSC21 is the industry's first fully programmable DSP-based processor designed exclusively for the unique challenges of digital imaging applications. It is a single-chip processing engine for digital still cameras that combines a TMS320C5000(TM) and an ARM7TDMI RISC processor for media processing and system control functions. The DSC21 enables real-time frame capture in burst mode to the full resolution of a 2-megapixel image sensor.

In a combined push to bring more Web-enabled electronic devices to market faster, RidgeRun, the leading provider of the Linux operating system for DSPs, will also offer a 30-day support package service to users of DevelopOnline via its online product development accelerator center. Working together, RidgeRun and DevelopOnline will enable shorter time-to-market by allowing the exploding community of Linux software programmers to access new technology platforms over the Web.

Through RidgeRun's support and DevelopOnline's site, developers can test drive RidgeRun's DSPLinux on one or more alternative new open platforms. Next, they can choose the best fit for their new product design, whether it is a set-top box, Internet appliance, Web pad, or PDA. Then, they can sign up for development support and begin to build their new electronic device — all on the same site.
