Intel and AMD death spell chip giant Bipin PMP market

Intel Corporation in the fourth quarter of 2003 launched the high-performance embedded processor-based XSCALE PXA270, architecture, up to maximum clock speed 624MHz. PXA270 most notably joined the Wireless MMX technology, greatly improving the multimedia processing power; at the PXA270 has also joined the Intel SpeedStep dynamic power management technology, ensuring the CPU performance, minimize mobile device power consumption! not specifically for the PXA270 PMP design, it initially appear on the PDA (such as Hewlett Packard HP4700) and smart phones (such as MOTO E680). Chose the PXA270 processor as PMP is derived from its powerful multimedia processing capacity and unique energy-saving technology. These two technologies are critical to the PMP products! plus Intel specifically for its tailor-made 2700G Multimedia Acceleration chip, the PXA270-based PMP programme would be unprecedented powerful! AMD company is not to reinvent the PMP market, 2005 introduced specifically for design of processor AU1200 PMP. AMD in embedded market injustices, this can be tailored to the PMP market launch of a dedicated processor, there seems to be very optimistic about the market AMD. In fact, these two years the explosive growth of MP3 and MP3 is high-end, we can clearly see the future of the PMP market claims its hot! AU1200 have strong multimedia processing power and very low power consumption.　　And PXA270, AU1200 provides rich interfaces, such as camera interface, SD/SDIO/MMC etc. The following breakdown, we will compare the processor's features and performance: a PXA270 312MHz, clock speed: ~ core high-performance scalable 624MHz AU1200: 333 MHz ~ 500MHz MIP32 core simple comparison of clock speed and not much significance, from the official announcement of product standards, and the frequency of processing power and PXA270 AU1200. PXA270 tie 2700G maximum video output resolution is 1280 × 1024, and AU1200 up to 1024 × 768. But WirelessMMX technology for multimedia processor performance of approximately 30 per cent, the ability to convert multimedia processing, the same frequency than the PXA270 AU1200 should also be 30 percent. 2. energy-saving technology AU1200 PXA270: SpeedStep Technology: dynamic sleep technology Intel SpeedStep technology originally used for mobile processor, this technology is used in popular language expression is the system needs more high frequency, it will adjust to high frequency, the system does not need, it will be the processor clock speed regulation to a minimum, not wasting a little. From the technical information we can learn, SpeedStep technology can be the clock speed in the PXA270 26MHz ~ 624MHz (highest) adjustable between! this means that the system is completely idle, PXA270 can run on the clock speed of 26MHz! now its power consumption is less than 0.1 Ma! AU1200 claimed power consumption is less than 400 Ma, for power saving technology and not very detailed descriptions. Third, the multimedia format supports PXA270 and are embedded processor AU1200. Processor-based solutions for the multimedia audio and video are processor computing capacity, combined with the software, which is the so-called soft solutions or soft pressure. In theory, software decoding methods for multimedia format support is not restricted. In other words, as long as capacity allows the PXA270 and AU1200 can support any format. Currently available with AU1200 PXA270 support MPEG-4 MPEG-1, MPEG-2, DIVx, XVID, AVI, WMV9, and other formats. But at the moment of the PMP programme based AU1200 will not support RealVideo! current Internet movie files most RM/RMVB format for, AU programme does not support RM format, say that it is a great pity!, the current domestic company launched the PXA270-based PMP solution enables RM/RMVB format support.　　4. extended interfaces PXA270: SD/SDIO/MMC and CF/PCMCIA, CMOS/CCD CAMERA, MS/MSPRO, USB2.0, OTG, IDE, LAN, SIM interface, KEYBOARD, etc. AU1200: SD/SDIO/MMC, CMOS CAMERA, USB2.0, OTG, IDE, etc extension interface, PXA270 to richer! this mainly originate from the PXA270 does not develop specifically for PMP, but rather a broader ground on PDA, smart phone, PMP, etc. AU1200 interface, while not abundant, but it should be said that more practical, and cost savings. 5. extended features in the extended functions PXA270 is much more advantageous AU1200!, after all, the market position of 270 is a handheld multimedia entertainment center! so PXA270 have 3D acceleration, satisfying game application; up to 4 million pixel CCD camera, digital camera with powerful; support LAN interface, you can extend the Web application. 6. programme launched by the time of maturity because of the relatively late, the current domestic solutions based on AU1200 No. Internationally, only Taiwan FIC of mature solution, but the FIC is OEM, facing the customers mainly heavyweight international consumer electronic brands. PXA270 although introduced a long time, but in the PMP applications also few manufacturers are doing. As far as I know, the only Shenzhen deep uni-video company launched the PXA270-based PMP solutionCase. From the above analysis, market positioning with AU1200 PXA270 is not the same, AU1200 specifically for PMP market launch, and PXA270 is multimedia digital entertainment center. In a regular audio and video processing capabilities, the difference with AU1200 PXA270 is not obvious, but the audio and video format support, a slight advantage PXA270.
