1/15/2003 - IBM and MontaVista Software Inc. announced a combination of technologies that could significantly extend battery life in consumer electronic products. The companies have shown that pairing the IBM PowerPC® 405LP embedded processor with MontaVista Linux Consumer Electronics Edition (CEE) may reduce processor power consumption as much as 50 percent. This could translate to an estimated 20-percent overall power savings in a wide range of products such as smartphones and personal digital assistants (PDAs), helping extend battery life and reducing their size and cost.
Limited samples of the IBM PowerPC 405LP are available now from IBM and volume production will be available in the third quarter of 2003; MontaVista Linux CEE is expected to be available from MontaVista Software in the first half of 2003.
"As pervasive computing becomes increasingly prominent in today's mobile world, enhanced low-power solutions that conserve precious battery charge are a critical customer requirement," said Lisa Su, director, PowerPC and emerging products, IBM Microelectronics. "From the architectural efficiency of PowerPC to the dynamic voltage and frequency scaling which we enable together with MontaVista Software, IBM is focused on delivering the underlying technologies to meet these needs."
The announcement is part of an ongoing effort by IBM and MontaVista Software to develop improved power saving techniques using what the companies call "Dynamic Power Management," specifically developed with the needs of power-sensitive embedded applications in mind.
"With this joint effort, MontaVista Software continues its track record of cutting-edge technology development and delivery. We are leading pioneering efforts in Open Source to enable embedded Linux systems to leverage the advanced power management in next-generation processors from leading chip suppliers like IBM, " said Kevin Morgan, vice president, Engineering, MontaVista Software.
Power management has traditionally focused on the reduction of power consumption in computer systems by placing them into static modes such as sleep and suspend when not in use. Dynamic Power Management techniques are designed to save power automatically, even as the system is in use, without requiring any action on the part of the user. For example, in the small amount of time between frames of an MPEG4 video clip, voltage can be ramped down and back up in time to handle the next frame, saving energy between each and every frame of the video.
White Paper Available
As part of the IBM, MontaVista power management efforts, a white paper titled "Dynamic Power Management for Embedded Systems" has been released for public access and to invite comment for interested software developers. The white paper proposes to standardize a dynamic power management and policy framework to support different power management strategies, either under control of operating system components or user-level policy managers. While dynamic power management has been the topic of research for many years, only recently have processors become available that could take full advantage of dynamic voltage and frequency scaling.

About the IBM PowerPC 405LP
The IBM PowerPC 405LP embedded processor is a 32-bit RISC processor offering high performance and ultra-low power for a wide variety of power-sensitive embedded applications, including mobile phones, PDAs and handheld computers. Using IBM's customer chip-making techniques, additional features can also be added to the PowerPC 405LP to adapt the device to other applications. IBM's low-power offering can help reduce the cost and time required to design new products, opening the door to all types of connected consumer electronics.
About MontaVista Linux Consumer Electronics Edition
MontaVista Linux Consumer Electronics Edition 3.0 (CEE), announced last week, is the first Linux operating system and cross-development environment specifically designed for consumer electronics applications such as mobile phones, digital televisions, set-top boxes and automotive telematics. CEE enhances Linux with dynamic power management, rich consumer-focused networking support and consumer-grade reliability. CEE targets consumer device specific CPUs such as the Texas Instruments OMAP1510 and OMAP5910 Innovator and the IBM PowerPC 405 LP, with others to follow. It forms the foundation of solution stacks from software partners in key vertical mobile, home and automotive markets. CEE is tailored to the demands of highly constrained mobile devices, which require low power consumption, restricted memory size and short boot and resume times. CEE 3.0 incorporates file system enhancements and new tools to measure performance, system timing and memory size. MontaVista Linux Consumer Electronics Edition supports XIP (eXecute In Place) of the kernel and applications as well as streaming media optimizations. It integrates with consumer market middleware such as the J2ME compatible WebSphere Micro Environment from IBM, and graphics packages such as QT/E from Trolltech and MontaVista Graphics.
