Description
Technical field
The present invention relates to a kind ofly can pass through computer network, guiding is based on the computing equipment of Godson framework, the remote boot chip and the correlation method of network computer that especially can the transparent computation schema of remote boot.
Technical background
Demand with the people is the center, and it is that main main frame calculates the network calculations stage that tabletop machine is the master that the development of computing technique has been experienced by large scale computer.Current, again just towards the immanent network calculations that comprises various mobile devices (for example mobile phone, notebook computer, PDA etc.) and digital household appliances, general fit calculation direction just develops based on the network calculations of tabletop machine.
But, in general fit calculation up to now and the computation schemas such as network calculations before general fit calculation: which kind of computing machine no matter, must will and corresponding operating system, supporting tool and application software be installed for its development from the beginning, otherwise this machine just can not carry out application corresponding calculating or running corresponding software system.This caused present to PC index (for example internal memory, hard disk, cpu frequency and speed etc.) require more and more higher, operation system of software becomes increasingly complex and huge situation.Those can only install the mobile device (as PDA, mobile phone etc.) of low profile edge operating system and digital household appliances (as ISDN phone etc.) though the less software that can turn round, but they are difficult to satisfy the growing types of applications demand of people, and be faced with very difficult and general calculation machine network system, for example INTERNET interconnects and the problem of intercommunication.The continuous upgrading of the one-to-one relationship of hardware system and software systems and hardware system makes software systems become increasingly complex, and user's operation and maintenance cost is more and more higher.Simultaneously, the old computer equipment of constantly eliminating forms many new rubbish again and causes new environmental pollution.
Transparent calculating is (referring to list of references: Zhang Yaoxue, " transparent calculating: notion, structure and example ", electronic letters, vol, Vol32, No12A, 12,2005) be the place that a kind of user need not perception computer operating system, supporting tool and application program, and can from employed various device (comprising various kinds of equipment fixing and mobile and family), find the correlation computations service, and these services be the computation schemas that are stored in the server that is arranged in distributed network according to the demand of oneself.
This pattern is made up of server and client computer, and is similar to traditional client/server on hardware system.Different is that in transparent computation schema, its client computer can be multiple different terminal device (PDA, portable terminal, household electrical appliances etc.).
Be not both with another of computation schemas such as legacy clients/server is important, in other any computation schemas, each different computing equipment is all corresponding with a specific operating system, this is not only the physical layer interface of hardware device and the needs of operating system nucleus coupling, also is traditional mode up to now; Transparent calculating then makes the user can see through an equipment and goes a plurality of operating systems and the application program selecting and use the user to need and like, and, these operating systems and application program are not to be fixed in this equipment, download from the server that stores these operating systems, instrument and application program etc. and obtain but see through various communication networks.As long as the hardware interface of equipment is to support these operating systems, the user is dynamic download and these operating systems, instrument and application program etc. dynamically are installed as required just, and the existing system and program in the covering client computer, thereby save the storage space and the computing time of client computer in a large number.
Another strong point of transparent calculating is that its server only is used for the storage of various resources, does not calculate and be not engaged in to use, and calculates and is finished by client device.The load that this has reduced server has improved user's response speed.
The characteristics of above-mentioned transparent calculating make to adopt the computing equipment of this pattern or system when need not the user and carrying out loaded down with trivial details installation/customization work one by one, satisfy the demand of user capitally for types of applications such as multimedia, internet, electronic offices, and because client need not to carry out in advance any configuration and management, calculate as required and take place, computational resource and service are stored and are managed by server, so also have high manageability, ease for use and security, it disposes also very easy.
Godson CPU is China's first item high performance universal central processing unit, supports the MIPS instruction set, has high security, high universalizable, high reliability and low in power consumption.The Godson hardware structure is made of Godson series CPU and corresponding mainboard, is suitable for using in all kinds of computing equipments.Godson series CPU succeeds in developing, broken CPU industry a situation in the world by the monopolization of several companies, but present Godson series CPU compares other main flow processors, its dominant frequency and computing velocity are all lower, its promotion and application are on the whole or all demand urgently on the amount improving that this also becomes one of factor of its industrialization of restriction.
As a kind of pattern of general fit calculation, the characteristics of transparent calculating have determined in its computing equipment applicable to various hardware architectures and computing power: even if the computing power of client is limited, also can support to move various large-scale application software admirably.Therefore,, not only will more effectively utilize its limited computational power to support more eurypalynous application to calculate, satisfy user's demand better as if the computing equipment that can on the Godson framework, develop based on transparent computation schema; And help expanding its range of application to need more client is carried out in (as the network classroom, E-Government, IT application in enterprises or the like) application scenarios that scale disposes.
In transparent computation schema, the local no hard disk of client device, the computational resource that comprises operating system etc. all needs obtain from server by network, and therefore for realizing transparent computation schema, client at first needs the remote boot chip that can support transparent computation schema.But in the prior art, still there is not the remote boot chip that to support Godson framework under the transparent computation schema, therefore the present invention proposes a kind of remote boot chip of the transparent computing equipment based on the Godson framework, how to have solved problem in the enterprising line operate system bootstrap of this computing equipment.
