Wireless technology advancement had been initiated with the improvement in the microprocessor designs to accommodate a host of features and applications, like, web browsing, 3-D gaming, camera, video etc. The basic architectural designs that have been improvised are RISC and CISC processors…
The leading companies like, Intel, Motorola and Texas Instruments etc, have contributed significantly towards the growth of mobile processors. The paper compares and critically examines three different products (embedded microprocessors) on the basis of five comparison criteria; power consumption, code density, peripheral integration and chipsets, multimedia accelerators and performance.
Microprocessors came into existence with the advent of computer technology. Since then, there has been a steep increase in the technological advancement with each new technology replacing the old counterpart in a matter of a year or two. Power consumption and dissipation, among these processors, was not a cause of concern as the issue could be easily addressed by use of fans with processors to keep them cool apart from providing an air conditioned environment. This arrangement sounds good for desktop applications only, while mobile applications warrants good performance in open environment with stored power sources (batteries) and no cooling mechanism (Schlett, Manfred., 1998).
With the wireless technology boom and rising demands of services on mobile platforms like, PDAs, cellular and smartphones, the embedded processors faced a number of challenges, of which power management (for longer battery life), processing speed (for better access to services) and memory management became far to important (Conte, Thomas M., 1997). ...
