The slogan “More GHz for less energy consumption” has become a motto in the development of the modern market of mobile devices – exactly this movement vector has led to the appearance of new low-power processors with integrated multimedia interfaces on chips, created especially for this segment of devices. In spite of the fact that solutions on the basis of ARM architecture have already become de-facto a standard in mobile electronics a long time ago, chip manufacturers keep surprising users and developers by capabilities of their processors (SoC – systems-on-chip).
Promwad Innovation Company reviews the most popular processors and software platforms for mobile devices capable of satisfying even the boldest demands of both product companies and consumers.
Samsung is one of the indisputable leaders in the market of mobile electronics – it produces highly-integrated systems-on-chip (SoC) built on the basis of ARM926-EJS and ARM920 processor cores. The family of S3Cxxxx processors is designed for application in portable and embedded devices – smartphones, pocket computers and navigators (PDA and PND), etc. The fact that Samsung also manufactures Flash and SDRAM memory gives it a certain advantage in price and form-factor. This is particularly obvious for SoCs used in mobile phones where PiP (Package-in-Package) and Stackable Package technologies are applied (i.e. RAM, Flash and processor in one package).
Another favorite is Freescale, who follows the policy of consecutive development of its ARM processors from the i.MX family – specially designed for application in smartphones, portable media players, navigation devices and in many other consumer, industrial and medical embedded systems. Built on the basis of different ARM® core versions (ARM9, ARM11 and ARM Cortex A8) i.MX family is created with application of Smart Speed technology providing high performance with low power consumption.
Marvell has become a remarkable player in the market of processors for mobile devices after purchasing XScale technology and PXA family from Intel. Further development of XScale has led to the appearance of high-performance and low-power Sheeva architecture.
Software platforms for mobile devices
It is certain that all power and diversity of interfaces and capabilities of System-on-Chip can be only implemented in full extent only by applying developed operating systems together with modern software platform meeting modern requirements of the market of mobile devices. Different consortiums were created for promoting software platforms on the basis of Linux. The most popular and developed among them are – Moblin, Android and Maemo.
