Napa is the name of Intel's third-generation mobile technology platform. It consists of an Intel 945 series chipset, a Yonah Pentium M processor, and an Intel 3945ABG wireless network adapter module. Compared to the second-generation Centrino Sonoma platform, it has the largest technology upgrade. The system bus speed is increased to 667MHz. The Yonah processor introduces single- and dual-core technology and uses 65nm process. The IntelPro/Wireless 3945ABG wireless module is compatible with 802.11a/b/g three network environments. Among them, the Yonah Pentium M processor began to introduce dual-core technology, which is a key technology of Napa.
1. The Yonah Pentium M processor in the Napa platform, most notably the dual-core Yonah Pentium M processor, is a new generation of mobile processors using 65nm process, but still using Socket 479 pins. In addition to the introduction of dual-core technology, the front-side bus speed has been increased to 667MHz, SmartCache technology, a new generation of power management technology, and the beginning of support for SEE3 multimedia instruction set due to the existence of dual-core.
Yonah Pentium M dual-core is Intel's first product to introduce dual-core technology into mobile processor products. It has two core units embedded in one processor and shares 2M L2 secondary cache through SmartCache technology, according to the load of processing tasks. The degree of coordination between the two core processing units, and then perform instruction operations at the same time, so as to achieve more efficient processing capabilities. Dual-core technology addresses the overall performance of concurrent multi-tasking operations.
Although the Yonah dual-core Pentium M has two cores, but the cache is shared using SmartCache technology to use 2M L2 cache, and the two cores are not separately designed for the second-level cache, so increasing the bus speed to 667MHz will reduce the number of processors and chips accordingly. There is a possibility of bottlenecks in communication between groups.
The introduction of dual-core technology, although the performance has been an absolute improvement, but also improves the processing efficiency of multi-task concurrent operations, but for mobile processor products, power consumption has not been the corresponding control is also the user's most concerned . In the Yonah Pentium M processor product line, the single-core Yonah processor consumes the same power as the Dothan processor, while the dual-core Yonah regular version has a maximum operating power of 31W and the ultra-low voltage dual-core Yonah Pentium M has only 9W. Single-core 15W, common single-core 27W, single-core Yonah processor power consumption than the corresponding Dothan processor remains the same level, while the dual-core version of the Yonah processor power consumption has increased, so Intel introduced the name Intel Dynamic Power Coordination technology and Enhanced Intel Deeper Sleep energy-saving technology enable the Napa platform to adjust power consumption according to the user's application more rationally. Combined with Intel SPeedstep automatic frequency modulation technology, the Napa platform will improve overall power consumption accordingly.
Intel Digital Media Boost is also a new technology introduced by the Yonah processor. Its main focus is on SSE/SSE2 Micro Ops Fusion, increased SSE decoder capacity, and support for the SSE3 instruction set. The introduction of this technology will increase the number of Yonah processors. The performance of multimedia applications will be improved for home users. For example, video clips, video playback, and other applications will improve performance and effectiveness.
2. The Intel 945 chipset series Calistoga is the codename of the mobile Intel 945 series chipset. Compared to the Intel 915 series chipset, the Calistoga chipset provides a system bus to 667MHz, supports DDR2 dual channel memory, and supports 667MHz (PC5300) at the highest speed. Support PCI-Express x16 interface technology, Intel 945GM integrated Intel Graphics Media Accelerator 950 display unit, 400MHz display core, and enhance shared system DDR2 667MHz memory for memory.
The Intel 945 Northbridge is equipped with the ICH7-M South Bridge, which supports six PCI-Express x1 interfaces. It also supports PCI and SATA-300 hard disk interfaces, supporting up to 3Gbps transfer rates. In addition, HD Audio audio technology is also supported.
3. The Intel Pro/Wireless 3945ABG wireless module Napa will use the Intel Pro/Wireless 3945ABG wireless module, which supports the IEEE 802.11a/b/g wireless network protocol and will be used in Napa to change the PCI interface used in Sonoma and previous Carmel platforms. Start using the PCI-Express x1 interface, and the module's specifications have also changed to a smaller mini-card.
The undoubted maximum benefit of the WiFi-based mini-card based on the PCI-Express x1 interface is that it can save some resources for the machine, and it can be more portable in line with the laptop body size. However, at present, some of the Napa platform's engineering prototypes are still based on PCI. Interface Intel 2200BG wireless module, so in the future Napa products, these two wireless modules will exist at the same time, need a transition period to complete the transfer of two generations of wireless modules.
Compatible with 802.11a/b/g three wireless network protocols, which can make Napa have a wider range of applications. With the wireless network market developed with Centrino technology, it is currently compatible with 802.11b/g dual-mode wireless. Environment, and 802.11a wireless environment with stronger anti-interference ability are used in some special fields.
