second generation Centrino: the new Intel Centrino Mobile technology platform (codenamed Sonoma), the platform by the Dothan core 90nm process (2MB L2 cache, 533MHz FSB) PentiumM processor , New Calexico2 Aviso chipset, new wireless modules (Intel PRO/Wireless 2200BG or 2915ABG wireless local area network components) made up of three main parts.
main features:
with the Banias core compared to Dothan processor has three main areas of change. First promoted from 0.13 Micron production process to the new 90 nm to create smaller and faster transistors, Dothan in 1 time-fold increase over the Banias processor Cache case, volume and power consumption has remained virtually unchanged. Second Dothan used a new "strain of Silicon" material technology. According to Intel tested strain in Silicon electronic flow faster than other Silicon electronic current faster, make Dothan at up to be a large upgrade, now has reached the highest 2.13G. In addition Dothan secondary cache upgrade to 2MB, in the case remain roughly the same energy consumption, relative to the original with the frequency of Banias around 20% Pentium-M processor performance gains. Dothan CPU from multifaceted to reached energy saving consumption of purpose, its second level cache used has 8 road joint of run mode, and each road and was segmentation became 4 a power regional, because in processor work process in the same time only using which of a power regional, so in dedicated of stack management technology control Xia close current cannot was using to of power regional, to greatly reduce has second level cache of power. In addition, Dothan CPU support Enhanced SpeedStep technology on energy saving of the new, the technology simply done by the processor voltage adjustment mechanism, and the chipset's relationship is unlikely. Switching between these modes of operation, all is automatic, based entirely on the processor load at the time, which will enable energy consumption to obtain precise control, achieve the purpose of more efficient.
Centrino concepts: Intel Centrino Mobile technology is Intel's best notebook technology. It's not just a processor, but also feature integrated wireless LAN capability, excellent mobile performance, light and portable, thin notebook form factor provides durable battery use time. These components include the Intel Pentium m processor, Mobile Intel 915 Express Chipset family or Intel 855 chipset family, Intel Pro/wireless network connection family.
3. Supports durable battery use time: Intel Centrino Mobile technology delivers exceptional mobile performance, at the same time with the following energy-saving technologySupports durable battery operation time, intelligent power distribution technology to power assigned to the application processor demands the highest level of the system. New energy-efficient transistor technology to optimize the use and consumption of energy in order to reduce the energy consumption of the CPU. Enhanced Intel SpeedStep technology support to dynamically enhance application performance and power usage.
2. Outstanding mobile performance: facing today's multitasking mobile computing life, when away from home or Office, also want outstanding mobile performance. In view of the mobile computing application becomes more complex, and require faster, more efficient computing performance, Intel Centrino Mobile technology is designed, aimed at providing faster order execution speed with lower energy consumption, which fully meet the needs of emerging and future applications. Intel Centrino Mobile technology supports the outstanding mobile performance in some of the main features include: micro-ops fusion, to merge operations, thus reducing the time and energy required to execute instructions. Energy-saving second-level cache and enhanced data prefetch capability can reduce external memory access times, and improve the availability of valid data in the secondary cache. Advanced instruction prediction analyzes past behavior and predicts which operations may need in the future, so as to eliminate duplication of CPU processing. Dedicated stack manager can perform general "housekeeping" functions to improve processing efficiency.

increase of new technologies: new Intel Graphics Media Accelerator 900 graphics core, energy-saving 533MHz front side bus and dual channel DDR2 memory support, help with integrated mobile Intel 915GM graphics express chipset system, get double the graphics performance boost. In addition, the new Intel Centrino Mobile technology also supports the latest PCI Express graphic interface can provide high-end system with discrete graphics with up to 4 times the graphics bandwidth. In support of the system manufacturer, also available such as TV tuner, supports Dolby Digital and the Intel high definition audio with 7.1 surround sound, personal video recorder and remote control options, while continuing to enjoy the Intel Centrino Mobile technology computation with durable battery life benefits. Can help manufacturers achieve durable battery characteristics include: display the energy-saving technology 2, low-power DDR2 memory support, and enhanced Intel SpeedStep technology.
4. A wide variety of notebook designs: Intel Centrino Mobile technology can support a lighter thin to full size design of the latest laptop. To integrate high performance processors into the latest slim and ultra slim laptop Hp Pavilion Zv5000 Battery, Tablet PC and other leading computer design, Intel Centrino Mobile technology uses Micro FCPGA (flip chip pin grid array) and FCBGA (flip chip ball grid array) technologies, to support specifically for the thinner, lighter notebook designs optimized for packaging processor chips. New laptops and smaller form factor design need special consideration to reduce energy consumption Dell Inspiron 9400 Battery, to control the heat dissipation. In order to meet this requirement, Intel Centrino Mobile technology with the low voltage (LV) and ultra low voltage (ULV) technology supports processors running at a lower voltage, thereby reducing the heat dissipation of flat and ultra slim design laptop.
3. new wireless module Calexico2: mobile computing one of the most important trend of development is to promote large-scale wireless local area network (Wi-Fi) application. Support for wireless connectivity Intel Centrino technology one of the core content. However compared to Dothan processor and Alviso, chipset, Calexico2 wireless module technology innovation degree manifestly inadequate Dell Vostro 2510 battery, because the same technology as early as two years ago, actually has a separate product, Intel just be integrated into the Sonoma mobile platform, and named Calexico2.
at the Sonoma mobile platform integration "Azalia" sound technology , The biggest advantage is to have excellent performance, that is, parallel processing and standardization framework. Azalia technical support up to 32bit/192kHz the audio sample rate, and 7.1-channel output. In addition, Azalia unified bus driver control will be used, because any Azalia audio devices can use the same drive. Azalia audio technology will bring unprecedented laptop audio effects, combined with increasingly strong performance moved display technology, will allow laptop play games become a pleasure.
PCI Express bus in Alviso chipset will fully replace the AGP bus and PCI bus. This is one of the most gratifying progress, no more data transfer bottleneck and troubled in the future. Great upgrade of bandwidth for video processing, multimedia production lead role not to be ignored. PCI Express bus also has low power consumption characteristics, is quite critical for notebooks. At the same time the new system will also be used with a high performance, low power DDRII memory, and supports dual-channel, will be able to provide the maximum bandwidth of 8.4G/s so well after the meetLong time processor development needs, at the same time also a lot of good to the promotion of integrated graphics performance. With the Sonoma platform Dell Inspiron E1705 Battery, Intel will launch "Extreme Graphics 3" integrated display chip, hardware support PS 2 VS 2 and DirectX 9, also uses a special power management technology to reduce power consumption, can let users freedom of choice between performance and power consumption. New memory consolidation package model, core and memory in the display on the same substrate, doing so is to increase the benefits of video memory with the speed of data exchange between the core and effectively reduce the volume.
