Description
Technical field
The present invention relates to moving communicating field, be meant the means of communication of a kind of portable terminal and processing module thereof especially.
Background technology
Along with to portable terminal intellectualities such as mobile phones, the requirement of multimedization is more and more higher, and is also more and more higher to the functional requirement of the processor in the mobile phone.In order to realize that a mobile phone can support many nets, support 2G and 3G simultaneously as mobile phone, the demand of multi mode terminal has been proposed.In the exploitation of multi mode terminal, for the application end exploitation that makes mobile phone get in touch still less with the exploitation of wireless side or correlation littler, promptly the software for same application end can mate more eurypalynous mobile phone wireless communication, as GSM (Global System for MobileCommunications, global system for mobile communications), WCDMA (Wideband Code DivisionMultiple Access, Wideband Code Division Multiple Access (WCDMA)), TD-SCDMA (Time Division-Synchronous CodeDivision Multiple Access, the code division multiple access that time-division is synchronous) etc., the mobile phone framework of dual processor or multiprocessor is more and more favored in design, but communication between the multiprocessor and power consumption become a key issue in this framework.
For example, double-core (dual processor) platform software framework at existing mobile phone can be divided into AP (ApplicationProcessor, application processor) and CP (Communication Processor, communication processor) two subsystems, AP mainly comprises multimedia and other related application modules, embedded OS (as Symbian, Windows mobile, Linux etc.).CP comprises the protocol stack communication module, as GPRS (General Packet Radio Service, GPRS), and EDGE (Enhanced DataRate for GSM Evolutio, enhanced data rates for gsm evolution), 3G ﹠amp; HSDPA (High SpeedDownlink Packages Access, high speed downlink packet inserts).
The implementation of existing multi mode terminal mainly contains two classes:
1. as shown in Figure 1, AP, CP are individual chips, undertaken alternately by the universal serial bus mode between AP and each CP, as USB (Universal Serial BUS, USB), UART (UniversalAsynchronous Receiver Transmitter, UART Universal Asynchronous Receiver Transmitter) etc., wherein AP is provided with master controller and links to each other with universal serial bus, links to each other with universal serial bus and each CP is provided with slave controller; This mode because the rate limit of serial communication can not satisfy the above handset demand of 3G and 3G, is the USB FS mode of 12M even adopt bandwidth, and its payload bandwidth can not meet the demands.Especially carry out communication for serial modes such as adopting USB,,, then can increase the stand-by power consumption of complete machine, shorten the stand-by time of mobile phone if USB does not sleep at holding state; If the USB sleep then when needs AP/CP carries out communication USB is waken up, and the time that USB wakes up can not be satisfied the requirement of user experience at present.
2. AP and one of them CP constitute a SoC (System on a Chip, system level chip) chip, for example Qualcomm MSM7200 as shown in Figure 2, other each CP are individual chips, communication modes between SoC chip and other each CP adopts the universal serial bus mode, USB for example, UART etc.Wherein SoC is provided with master controller and links to each other with universal serial bus, links to each other with universal serial bus and other each CP are provided with slave controller.Be to adopt serial mode equally between the multiprocessor of this framework, have the problem of above-mentioned framework shown in Figure 1 equally, and with AP as main equipment, and each CP can't directly carry out communication as slave unit between each CP, and must participate in by AP.
The inventor finds that there are the following problems at least in the prior art in realizing process of the present invention:
Adopt serial mode to connect between each processor, and need AP as main equipment, each CP is as slave unit, and the communication between each CP must be passed through AP, makes that the communication efficiency between each processor is low.
