Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The business information of the polycaryon processor that the embodiment of the invention is mentioned comprises inner control information and outside data message; All kernels that the bright embodiment of this law mentions can be positioned at same polycaryon processor, this moment kernel between through internuclear data bus or shared drive business transferring information; All kernels also can be positioned at different polycaryon processors, and pass through data bus or shared drive business transferring information between polycaryon processor between the kernel this moment; All kernels can also be positioned at the different circuits plate, and pass through data bus business transferring information circuit board between between the kernel this moment.
The embodiment of the invention provides a kind of backup method of polycaryon processor business information, and wherein said polycaryon processor comprises a plurality of kernels, and is as shown in Figure 1, and said method comprises:
11, predefined kernel receives the business information of other kernel and sends to the corresponding backup kernel of said predefined kernel.
Particularly; For example predefined kernel is a kernel 1, and other kernel is kernel 2 and kernel 3, and the backup kernel of kernel 1 is a kernel 4; The backup kernel of kernel 2 and kernel 3 is respectively kernel 5 and kernel 6, and kernel 1 receives the business information of kernel 2 and kernel 3 and sends to kernel 4.
As optional, predefined kernel can also send to the business information of himself the corresponding backup kernel of said predefined kernel.
The business information of other kernel that the backup kernel that 12, said predefined kernel is corresponding will receive sends to the corresponding backup kernel of said other kernel.
Particularly, for example kernel 4 receives the business information of kernel 2 and kernel 3, and kernel 4 sends to kernel 5 with the business information of kernel 2, and the business information of kernel 3 is sent to kernel 6.
Further; For example if the business information of kernel 2 based on the business information of kernel 3; Because the business information of all kernels that need back up all will could be accomplished backup through kernel 1 and kernel 4; Accomplish backup through kernel 1 and kernel 4 earlier so the business information that produces earlier is certain; So the corresponding service information that the business information that produces owing to kernel 3 produces prior to kernel 2, so the business information that kernel 3 produces is bound to backup to kernel 6 earlier through kernel 1 and kernel 4, the corresponding service information of having avoided kernel 2 generations occurring is by first backup; And the situation that the business information that kernel 3 produces is not also backed up, thereby the sequence requirement of the business information of internuclear backup in having guaranteed.
In the said method; Predefined kernel can receive the business information that external transmission is given other kernel simultaneously with other kernel, and the said external transmission that predefined kernel will receive sends to the corresponding backup kernel of said predefined kernel for the business information of other kernel; The said external transmission that the corresponding backup kernel of said predefined kernel will receive is given the business information of other kernel and is sent to the corresponding backup kernel of said other kernel.For example; The external transmission business information is given kernel 2; This moment, predefined kernel 1 received the business information that external transmission is given kernel 2 simultaneously with kernel 2 so; The said external transmission that kernel 2 will receive sends to kernel 4 (the backup kernel of kernel 1 correspondence) for the business information of kernel 2, and kernel 4 sends to kernel 5 (the backup kernels of kernel 2 correspondences) for the business information of kernel 2 external transmission.Save kernel 2 like this business datum of this external transmission has been issued the step to kernel 1 again, thereby shortened the BACKUP TIME of business information.
The embodiment of the invention provides the backup method of another polycaryon processor business information, and is as shown in Figure 2, comprising:
21, kernel is saved in shared drive with the business information of self.
Particularly; Kernel according to the size of the business information of himself to shared drive application corresponding memory space; And the identity information of the backup kernel that said kernel is corresponding is as the sign of the corresponding memory space of said application, and self business information is saved in the corresponding memory space of said application.For example the backup kernel of kernel 1 is a kernel 4; The backup kernel of kernel 2 is kernels 5, and the business information size of kernel 1 is 15k, and then kernel 1 is to the storage space of shared drive application more than or equal to 15k; The business information of 15k is saved in this storage space; And with the identity information of kernel 4 sign as this storage space, the identity information of kernel 4 can be the numbering 4 of himself, also can be other information that is used to distinguish this kernel and other kernel.As optional, if shared drive is to share buffer queue, the storage space of kernel application all distributes from a high position to the low level successively so.
As optional; The sign of the storage space of above-mentioned kernel application also can be the identity information of said kernel self, and the identity information according to said kernel when predefined backup kernel reads the sign of this storage space sends to its corresponding backup kernel with the business information in the storage space.
22, predefined backup kernel reads the business information of said shared drive, the business information of the kernel that reads is sent to the backup kernel of said kernel correspondence.
Particularly; Predefined backup kernel reads the business information of said shared drive, the business information in the corresponding memory space of said application is sent to the corresponding backup kernel of sign of said storage space according to the sign of the corresponding memory space of said application.For example, if the numbering 4 that is designated kernel 4 (being the backup kernel of kernel 1) of the storage space of kernel 1 application, then predefined backup kernel sends to kernel 4 according to the sign (numbering 4) of storage space with the business information in this storage space.
Further; If predetermined backup kernel is the backup kernel (kernel 4) of kernel 1; And the business information of kernel 1 is based on the business information of kernel 2; Because the business information of all kernels that need back up all will be saved in the shared drive successively, and the business information of the needs backup that will preserve through kernel 4 is distributed in the corresponding backup kernel of each kernel successively, so the business information of generation necessarily is saved in earlier in the shared drive earlier; So because corresponding service information that the business information that kernel 2 produces produces prior to kernel 1; So the business information that kernel 2 produces is bound to be saved in earlier in the shared drive, then backups to kernel 5 earlier through kernel 4, the corresponding service information of having avoided kernel 1 generation occurring is by first backup; And the situation that the business information that kernel 2 produces is not also backed up, thereby the sequence requirement of the business information of internuclear backup in having guaranteed.
In the said method, kernel and shared drive receive the business information that external transmission is given said kernel simultaneously, and said shared drive is preserved the business information that said external transmission is given said kernel; Predefined backup kernel reads the business information of the said external transmission of said shared drive preservation to said kernel, sends to the corresponding backup kernel of said kernel for the business information of said kernel the said external transmission that reads.For example the external transmission business information is given kernel 1; This moment, shared drive and kernel 1 received the business information that external transmission is given kernel 1 simultaneously so; Shared drive is preserved the business information that said external transmission is given kernel 1, and predefined kernel 4 (the backup kernel of kernel 1) reads the external transmission of shared drive preservation and also backs up for the business information of kernel 1.Save kernel 1 like this business datum of this external transmission has been saved in the step of shared drive, thereby shortened the BACKUP TIME of business information.
The embodiment of the invention also provides a kind of employing master-slave mode that the polycaryon processor business information is carried out backup method; As shown in Figure 3; Main use kernel is 301,302 and 303; Its corresponding backup kernel is respectively 311,312 and 313, and kernel 320 responsible reception external datas are transferred to corresponding master and use kernel.
The business information that preestablishes kernel 302 and kernel 303 need send to kernel 301 and back up, and kernel 301 sends to kernel 311 completion backups with the business datum of self; The business information that kernel 302 will back up sends to kernel 301, and is distributed to kernel 312 completion backups via kernel 311; The business information that kernel 303 will back up sends to kernel 301, and is distributed to kernel 313 completion backups via kernel 311.If the business information of kernel 302 is based on the business information of kernel 303; Must be the business information that kernel 303 generations earlier need backup so; The business information of the needs backup of kernel 303 generations this moment sends to kernel 301 and backs up; Send to kernel 302 simultaneously and carry out the subsequent treatment of business information, further kernel 301 sends to kernel 311 with the business information of kernel 303, and sends to kernel 313 by kernel 311 and accomplish backup; And the business information that kernel 302 will back up after the business information of kernel 303 is carried out subsequent treatment again sends to kernel 301, and is distributed to kernel 312 completion backups via kernel 311.The sequence requirement of the business information of internuclear backup in so just having guaranteed.Simultaneously as optional; Kernel 320 receives external transmission when giving the business information of kernel 302; Can simultaneously this business information be sent to kernel 301 and kernel 302, kernel 301 directly sends to kernel 311 with this business information, and kernel 311 sends to kernel 312 to accomplish backup with this business information; Save kernel 302 like this this business information has been sent to the step of kernel 301, shortened the time of business information backup.
Said method is that business is shared mode the polycaryon processor business information is carried out backup method if Fig. 3 adopts; Then be that the business information that kernel 301, kernel 302 and kernel 303 are responsible for is backuped to kernel 311, kernel 312 and kernel 313 respectively, the business information that kernel 311, kernel 312 and kernel 313 are responsible for backups to kernel 301, kernel 302 and kernel 303 respectively.Preestablishing kernel 302 sends to kernel 301 and sends to corresponding kernel 312 and 313 respectively to accomplish backup via kernel 311 with kernel 303 responsible business information; The business information that kernel 312 and kernel 313 are responsible for send to kernel 311 and send to corresponding kernel 302 respectively via kernel 301 and back up to accomplish with kernel 303; Kernel 301 sends to kernel 311 to accomplish backup with the business information of self being responsible for, and kernel 311 sends to kernel 301 to accomplish backup with the business information of self being responsible for.
The embodiment of the invention also provides another to adopt master-slave mode that the polycaryon processor business information is carried out backup method; As shown in Figure 4; Main use kernel is 401,402 and 403; Its corresponding backup kernel is respectively 411,412 and 413, and kernel 420 is responsible for receiving external data and is transferred to the corresponding main kernel of using, and shared drive 430 is responsible for receiving main business information of sending with kernel 401,402 and 403; It should be noted that when shared drive and will lead the business information of sending when from a high position to the low level, preserving successively, also will read successively when reading according to the order from a high position to the low level with kernel.
