Creating Performance with Stamina for Wireless Communications White Paper, Rev. 2

Freescale Semiconductor
law—Shannon’s Law. It shows that communication system performance requirements are doubling every
eight-and-a-half months—about twice the rate of processor performance and
over fourteen times the rate
of improved battery life
.
This is why we work so hard to save energy in our designs, from transistor-level to system-level. We must
continue to push the performance limits, however, we cannot afford to emphasize speed over stamina. We
know that battery technology will never keep up with us, so it is up to us to close the gap between system
power requirements and the availability of battery power. Expectations are very high. We must offer
components and systems that OEMs and ODMs can use to build what consumers are
demanding—pocket-sized wireless communicators and business tools that are on whenever they need
them.
Think System
It’s important to keep in mind that i.MX is part of a larger Motorola wireless application system. The fully
integrated Innovative Convergence Platform offers the cutting edge chipset, software engine, and
development environment necessary for 2.5G and 3G cellular development that supports Bluetooth and
Java 2 Micro Edition (J2ME) implementation. Smartphone development hinges on successfully
combining cellular functionality with application processing in one handset. The platform is designed to
integrate the i.MX seamlessly with a companion cellular processor. Using this approach, we can change
and enhance the DragonBall processor without requiring the need to re-certify the cellular functionality of
the smartphone with the carriers. Motorola has leveraged over twenty years of cellular experience to
develop the i.250 platform for GSM/GPRS handsets and the i.300 for GSM/UMTS appliances.
Similarly, we’ve developed the CPU Platform for handheld computer applications, such as new PDAs with
such multimedia features as audio and video playback, as well as imaging capabilities. The Motorola i.MX
platforms are multi-OS and real-time-OS ready and include Bluetooth wireless technology-enabled
interfaces. Each platform is compact, highly integrated, and very power efficient, having been designed
and manufactured using the low-power, yet performance enhancing techniques discussed earlier. In
addition, we are among the first companies to offer an application processor with 1.8V I/O, offering an
efficient interface with the advanced 1.8V memory products. And we are continually expanding these
systems to offer support for new technologies and new services as they emerge in the marketplace—new,
advanced display technologies, including smart panels; streaming video; multiple operating systems; and
the far-reaching capabilities of the personal server.
