Description

A kind of modularization mobile hand-held device with bus structures

Technical field

The utility model belongs to field of communication technology, particularly belongs to a kind of modularization ambulatory handheld with bus structures and sets It is standby.

Background technique

Demand of the world market to mobile hand-held device is in the ascendant at present, and developing history is mainly small from desktop computer Type is derived, and several big systems are presented, the Windows CE system including X86 system, Android, Linux of ARM core System and the Symbian system of Nokia.Windows CE system belongs to PCI/PCIE bus from hardware structure X86-based, Android and Symbian, IOS system belong to the AMBA bus architecture of ARM core, and linux system is software system System, can reduce and operate on any one hardware system of X86 and ARM core.Mobile hand-held device is based on above-mentioned several hardware It is developed with software systems, i.e., using X86 kernel or using ARM kernel as hardware handles core, in core processor Perhaps functional module or offer dedicated service interface complete corresponding function to integrated diversification business interface bus.Current master The equal onboard data processing and exchanging module of processor and instruction repertorie processing module, this has become a kind of general technological means.

As mobile hand-held device is to miniaturization, energy conservation, multi-functional multi-service development, market is gradually presented uniform technical and becomes Gesture, i.e. Windows CE system and Symbian system disappear substantially, only have fragmentary utilization in part industrial application.And it adopts It is largely used with the IOS system of the android system of ARM core AMBA bus and Apple Inc..And ARM core becomes shifting on hardware The ruler in mobile handset field, X86 kernel are almost no longer used as the hardware-core in mobile hand-held device field.So Become this patent selective analysis field for the mobile hand-held device of ARM kernel, exists in hardware development and software development Following disadvantage:

[1] primary processor/modular service interface and service bus can not be reduced or be added.Mobile hand-held device main process task Device/module in order to reduce power consumption, improves chip processing capabilities, reduces peripheral circuit area, is integrated with commonly fixation mostly Interface, such as DCI, DSI, audio, Sensor etc. flexibly can not reduce or add main place according to the business demand of reality scene Manage the hardware interface of device.Cause there are problems that hardware interface redundancy or hardware interface deficiency in the application of certain concrete scene.

[2] primary processor/module model is chosen limited.Substantially it is monopolized by producers such as high pass, Samsung, Lian Fake.And apple The primary processor of company and Huawei Company/module not export trade substantially, causes purchase cost excessively high, development platform solidification, for spy The small lot exploitation scene for determining scene is unable to satisfy the demand of development platform flexible Application.

[3] software development efficiency is lower.After dedicated primary processor/module, internal drive program is by primary processor/mould The solidification of block producer, software system development can only call, and bottom code optimization or modification can hardly be made to it, cause debugging fixed Position development efficiency is lower.Software Development Platform needs multi-person synergy to develop, and the division of labor is clear, for Small Groups exploitation maintenance cost compared with It is high.

[4] purchase cost is excessively high.After application specific processor/module, there are buying master chips, it is necessary to purchase software kit Module or Integrated Development configuration surroundings, since little company's bargaining power and acquisition producer's technical support response speed cause more slowly Complete machine develops link higher cost, and especially after technical solution binds certain type primary processor, later procurement delivery cycle can not be controlled System causes the development cycle of project and purchase cost can not autonomous control.

[5] due to technical scheme binding chip producer technical solution, so unavoidably using chip producer Patented technology certainly exists license and charging problem after product large-scale production, to raise product cost, drops Low product profit is unfavorable for product and is mass produced and is quickly dominated the market with high performance-price ratio.
