The new laptops more compact design requires special consideration to reduce energy consumption, to control heat dissipation. To meet this requirement, Intel Centrino mobile technology uses low-voltage (LV) and ultra low voltage (ULV) technology to support the processor to run at lower voltages, thus reducing the tablet and ultra-slim design of the laptop heat dissipation.



Second-generation Centrino


Centrino generation: the new Intel Centrino mobile technology platform (codenamed Sonoma), the platform consists of Dothan core 90nm process (2MB L2 cache, 533MHz FSB) of PentiumM processor, the new Aviso chipset, the new wireless module Calexico2 ( Intel PRO / Wireless 2915ABG or 2200BG wireless LAN components) of three main components.


Added new technology: The new Intel Graphics Media Accelerator 900 graphics core, energy-efficient 533MHz FSB, and dual-channel DDR2 memory support, facilitate the adoption of systems with integrated graphics Mobile Intel 915GM Express chipset, double the graphics performance. Additionally, the new Intel Centrino mobile technology also supports the latest PCI Express graphics interface and can deliver up to four times the graphics bandwidth for high-end systems with discrete graphics. In the system manufacturer's support, are also available, such as a TV tuner, support for Dolby Digital 7.1 surround sound and the Intel High Definition Audio, personal video recorders and remote controls and other options, while continuing to enjoy computing with Intel Centrino mobile technology for durable battery time advantage. Can help manufacturers achieve durable battery features include: Display Power Saving Technology 2.0, low-power DDR2 memory support, and Enhanced Intel SpeedStep technology.


1. The new PentiumM Processor: Dothan processor on the basis of Banias on the introduction of a more mature NetBurst architecture of many other features, and adds Enhanced Data Prefecher (advanced data prefetch) and Enhanced Register Data Retrieval (advanced recording data re eligible) two new technologies.

Compared with Banias core products, Dothan processors have major changes in three areas. First, from a 0.13-micron manufacturing process to a whole new 90-nanometer, can produce smaller, faster transistors, Dothan processor adds Cache doubled the case, volume and power consumption remained unchanged compared Banias. Secondly Dothan adopted a new "strained silicon" material technology. According to Intel testing, strained silicon electrons flow much faster than the electron current to other silicon materials, so Dothan clock speed has been greatly improved, the highest has reached 2.13G. In addition Dothan secondary cache upgrade to 2MB, while maintaining approximately the same energy, the same frequency with respect to the original Banias Pentium-M processor performance by about 20%. Dothan CPU in many ways to achieve energy-saving purposes, the secondary cache uses 8-way set-associative mode of operation, and every road has divided the four-power region, since the processor work during the same time only use one power area, so close the current can not be used to power the region under special control stack management techniques, thereby greatly reducing the power consumption of the secondary cache. In addition, Dothan CPU Enhanced SpeedStep support the new energy-saving technology, which entirely by the voltage adjustment mechanism processor to complete, and little to do with the chipset. Operation switch between these modes, all is automatic, based solely on the processor load at the time, which would make the energy consumption be accurately controlled to achieve more energy-saving purposes.


2. The new Aviso Chipset: core Sonoma platform, in addition to Dothan CPU, but the key is the Alviso (915PM / 915GM) chipset, contains a lot of the latest technology, in addition to support PCI Express bus architecture, also includes support for low-power DDR- EG3 2 memory and a new graphics core, in addition, Alviso chipset codenamed ICH6-M with mobile Southbridge provides four Serial ATA hard disk interface, and integration of a new generation Azalia audio chip with the new ExpressCard external expansion interface. "Sonoma" as "Centrino (Centrino)" alternative products, its wireless, display and audio capabilities has been further improved, the calculation speed is improved by about 30%.

PCI Express bus in the Alviso chipset will completely replace the AGP bus and PCI bus. This is the most delightful progress, after no longer the bottleneck of data transmission to feel troubled. Bandwidth is a huge boost for video processing, multimedia production has brought can not be ignored. PCI Express bus also at the same time have a low power consumption, for the laptop is quite critical. While the new system will also match high-performance, low-power DDRII memory, and supports dual-channel, will be able to offer maximum 8.4G / s of bandwidth to meet the development needs after such a long period of time the processor, while integrated graphics improved performance is also good. With the Sonoma platform, Intel will launch "Extreme Graphics 3" integrated graphics chip, hardware support for PS 2.0 and VS 2.0 and DirectX 9, also uses a special power management technology to reduce power consumption, allowing the user in terms of performance and power consumption between the freedom of choice. The new memory integrated package mode, the graphics core and memory to do in the same piece of substrate and benefits of doing so is that you can increase the speed of data exchange between the memory with the core, and effectively reduce the volume.

On Sonoma mobile platform integration "Azalia" audio technology, the biggest advantage is with excellent performance, namely the parallel processing capabilities and standardized architecture. Azalia technology supports up to 32bit / 192kHz audio sample rate, and 7.1 channel output. In addition, Azalia uses unified bus driver control, because any Azalia audio devices can use the same driver. Azalia audio technology will bring unprecedented audio performance for notebook computers, with more robust performance of mobile display technology, will make playing games with the laptop becomes a pleasure.

On Sonoma mobile platform, the extension of the years of PCMCIA Card will be a great change. With the popularity of high-bandwidth video and network applications, traditional PCMCIA PC Card increasingly unsuited to such a situation. There is an urgent need for a new technology to replace. ExpressCard is one such technology, than the traditional PC Card technology lighter, thinner, faster, and easier to use. Except for the laptop ExpressCard34, as well as for desktop computers ExpressCard54, resulting in between laptops and desktops set up another bridge. Because ExpressCard between dimensions, performance, reliability, adaptability, hot-swappable and auto-set and other properties reached more ideal balance, and therefore used for many years it is likely to replace PC Card.


3. The new wireless module Calexico2: mobile computing One of the most important trends is a large scale wireless LAN (Wi-Fi) applications. One of the core content for wireless connections support Intel Centrino technology. But in terms of comparing Dothan processor and Alviso chipset, degree of technological innovation Calexico2 wireless module is obviously insufficient, because the same technology is actually two years ago have separate products appear, Intel just to integrate into the Sonoma mobile platform in, and name Calexico2 only.

On Sonoma mobile platform, Centrino technology as an important part of the wireless communication module, the configuration Calexico2 latest wireless communication module, supports IEEE 802.11b basis adds support for IEEE 802.11a / g two wireless technologies. Which operate in 5.0GHz band IEEE802.11a under, you can easily avoid interference from 2.4GHz band. In addition to the different frequency bands, IEEE 802.11a uses an improved information coding scheme, so that the transmission speed of up to 54Mbps. IEEE 802.11g and IEEE 802.11a technology has both the characteristics, but also has the characteristics of IEEE 802.11b. IEEE 802.11g operate in the 2.4GHz band, the thus achieve the purpose of compatibility with IEEE 802.11b, IEEE 802.11g but with IEEE 802.11a uses the same information coding scheme, so that the transmission frequency of the same 54Mbps.
