Phone architecture multiprocessor communication between the three main alternatives, namely the use of general-purpose embedded interface, laptop battery proprietary programs and multi-port memory. Multi-port program, designers can ensure sufficient bandwidth, not only to support existing 3G standard CDMA2000 1xEV-DO, etc., but also to support the running speed HSPDA 10Mbps and 54Mbps 802.11g next-generation wireless data interface.Although these phones have coverage and computing performance required by today's wireless applications, but they also bring potential performance bottlenecks. The new multimedia to process the request has been improving, forcing design engineers turned to dual-processor phone architecture, most multimedia tasks to be delivered to a separate application processor. In addition, both support 3G wireless standards can also support 802.11 and Digital Multimedia Broadcasting (DMB) high-speed wireless data interface, high-performance mobile phones is on the rise, which laid the foundation for the new generation of multi-mode mobile phone with three embedded processors.When the phone 802.11b Wi-Fi network access rate of 11Mbps or higher, these limitations will become more apparent. The notebook battery associated with the non-cellular wireless standard data transmission rate far exceeds the performance limits of 3G wireless systems. In order to best possible use of the performance of the DMB or 802.11 high-speed wireless interface specification, these phones must be able to support this high-speed transfer rate of inter-processor communication program.The second optional solution is to use proprietary solutions, this approach is more practical from a performance standpoint. The multiprocessor communication program can be customized ASIC or the proprietary bus provided by some embedded processor vendors. Asus A32-F82 accu Asus UL50 accu Asus X51R accu LG SQU-524 accu
