Centrino II: The new Intel Centrino mobile technology platform (codenamed Sonoma) is a 90nm process Dothan core (2MB L2 cache, 533MHz FSB) PentiumM processor, new Aviso chipset, and new wireless module Calexico2 ( Intel PRO/Wireless 2915ABG or 2200BG Wireless LAN Components) consists of three main components.
New additions: New Intel Graphics Media Accelerator 900 graphics core, energy-efficient 533MHz front-side bus, and dual-channel DDR2 memory support, enabling the use of a mobile Intel 915GM Express chipset system with integrated graphics for double graphics Improve performance. In addition, the new Intel Centrino mobile technology also supports the latest PCI Express graphics interface, providing up to 4 times more graphics bandwidth for high-end systems with discrete graphics. With the support of system manufacturers, options such as TV tuners, Intel HD audio, personal video recorders, and remote controls supporting Dolby Digital and 7.1 surround sound are also available, while continuing to enjoy durable batteries for Intel Centrino mobile technology computing Use time advantage. Features that help manufacturers achieve long-lasting battery life include: Display Energy Saving Technology 2.0, Low-Power DDR2 Memory Support, and Enhanced Intel SpeedStep Technology.
1. The new Pentium M processor: The Dothan processor introduces many features of the more mature NetBurst architecture based on Banias, and adds Enhanced Data Prefecher and Enhanced Register Data Retrieval. Two new technologies.
Compared to the Banias core product, the Dothan processor has three main changes. First of all, the production process was upgraded from 0.13 micron to a new 90 nanometers, and smaller and faster transistors can be manufactured. Therefore, the Dothan processor's size and power consumption are basically the same when the number of caches is double that of Banias. Second, Dothan adopted new "strained silicon" material technology. According to Intel's test, the flow rate of electrons in strained silicon is much faster than that of other current silicon materials, which has greatly improved Dothan's frequency, and it has now reached a maximum of 2.13G. In addition, Dothan's L2 cache is boosted to 2MB. Compared with the original Banias Pentium-M processor, the performance of the same-frequency Banas Pentium-M processor is about 20% higher. Dothan CPU achieves the purpose of saving energy and reducing consumption in many aspects. Its L2 cache adopts an 8-way combined operation mode, and each path is divided into 4 power consumption areas, since only the processor can work at the same time. One of the power consumption areas is used, so that the current power consumption area cannot be used under the control of a dedicated stack management technology, thereby greatly reducing the power consumption of the second level cache. In addition, the Dothan CPU supports the new Enhanced SpeedStep energy-saving technology. This technology is completely completed by the processor's voltage adjustment mechanism, and has little to do with the chipset. The operations to switch between these modes are all automatic and completely based on the load of the processor at the time. This will enable the energy consumption to be accurately controlled and achieve more energy-saving purposes.
2. The new Aviso chipset: The core of the Sonoma platform In addition to the Dothan CPU, the key is the Alviso (915PM/915GM) chipset, which contains a lot of the latest technology, in addition to supporting the PCI Express bus architecture, including support for low-power DDR-2 memory And the new EG3 graphics core, in addition, Alviso chipset also with a code named ICH6-M Mobile South Bridge chip, can provide four serial ATA hard disk interface, and integrates a new generation of Azalia audio chip and the new ExpressCard external expansion interface . "Sonoma" is an alternative to "Centrino" and its wireless, display and audio functions have been further improved. The calculation speed has also increased by about 30%.
The PCI Express bus will completely replace the AGP bus and the PCI bus on the Alviso chipset. This is the most gratifying advancement, and there is no need to worry about the bottleneck of data transmission. The huge increase in bandwidth has played a significant role in video processing and multimedia production. The PCI Express bus also features low power consumption, which is also critical for notebooks. At the same time, the new system will also be combined with high-performance, low-power DDRII memory, and support dual-channel, will be able to provide a maximum bandwidth of 8.4G / s, this can meet the development needs of the processor for a long time later, while the integrated graphics The performance improvement is also a great benefit. With the Sonoma platform, Intel will launch the "Extreme Graphics 3" integrated graphics chip, hardware support for PS 2.0 and VS 2.0, and DirectX 9, while also using special power management techniques to reduce power consumption, allowing users in performance and power consumption Free choice between. The new memory integrated packaging model, the display core and memory on the same substrate, the advantage of doing so is to improve the speed of data exchange between the memory and the core, and effectively reduce the size.
The biggest advantage of the "Azalia" sound technology integrated on the Sonoma mobile platform is its outstanding performance, namely parallel processing functions and standardized architecture. Azalia technology supports up to 32bit/192kHz audio sample rate and 7.1 channel output. In addition, Azalia uses the unified bus driver for control because any Azalia audio device can use the same driver. Azalia sound technology will bring unprecedented audio effects to notebooks. With more and more powerful mobile display technology, it will make playing games with laptops a pleasure.
On the Sonoma mobile platform, PCMCIA Cards that have been used for many years will also undergo great changes. With the popularity of high-bandwidth video and network applications, traditional PCMCIA PC Cards are becoming less and less suited to this situation. There is an urgent need for a new type of technology to replace. ExpressCard is a technology that will be lighter, thinner, faster, and easier to use than traditional PC Card technology. In addition to the ExpressCard 34 for laptops, there is an ExpressCard 54 for desktops, which provides another bridge between laptops and desktops. Because ExpressCard achieves a better balance between features such as form factor, performance, reliability, adaptability, hot swapping, and auto-setup, it is likely to replace PC Cards that have been used for many years.
3. The new wireless module Calexico2: One of the most important trends in mobile computing is the large-scale promotion of wireless local area network (Wi-Fi) applications. Support for wireless connectivity One of the core elements of Intel Centrino technology. However, compared to the Dothan processor and Alviso chipset, the Calexico2 wireless module's technological innovation level is obviously insufficient, because the same technology actually had an independent product as early as two years ago, and Intel just integrated it into the Sonoma mobile platform. And named it Calexico2.
On the Sonoma mobile platform, the wireless communication module, which is an important part of Centrino technology, will be equipped with the latest Calexico2 wireless communication module, and adds support for the IEEE 802.11a/g wireless technology on the basis of IEEE 802.11b support. Among them IEEE802.11a works under the 5.0GHz frequency band, can avoid the interference from 2.4GHz frequency band easily. In addition to the different frequency bands, IEEE 802.11a uses an improved information encoding method, which allows transmission speeds up to 54 Mbps. IEEE 802.11g technology has both IEEE 802.11a features and IEEE 802.11b features. IEEE 802.11g operates in the 2.4 GHz band, and thus achieves the purpose of compatibility with IEEE 802.11b. However, IEEE 802.11g uses the same information coding method as IEEE 802.11a, which also enables the transmission frequency to reach 54 Mbps.
