Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
As shown in Figure 1, be a common veneer model, in the communications field, arrange that on this veneer chip array has become the technology of comparatively popularizing.
Core concept of the present invention, it is the program section of being divided into by loading, by paragraph header stage casing each section of sequence number information identification index, the method that loads at interval each section one by one according to certain hour during loading procedure is avoided program loaded with traffic taking for a long time bus, to eliminate influence, after loading is finished, be reassembled into complete program file to newsletter, thereby the dynamic load of the program of realization can non-interrupting service communication when promptly program loads.
As shown in Figure 2, be the process flow diagram that the present invention loads.
The present invention is before loading, can load a very short primary control program, this primary control program carries program and loads required configuration information, loads which file such as needs, program start address or the like, and mainly finish control and message processing function to the process that loads.
The loading of this program, (HOST) finishes input by main frame, and this main frame can be the LOCAL CPU on the chip array veneer, also can be the master control veneer in the system, even can be the backstage of a system.
When loading this primary control program, except using the main frame loading, can also load by BIOS.
In the process that primary control program loads, if primary control program loads successfully, then return correct message, reload otherwise return error message and require.If when the number of times that reloads surpasses certain threshold value, then stop to load and reporting error event message.Such as, we are set to 3 at threshold value, when then surpassing 3 times, stop to load and reporting wrong time message.
For the program of desire loading, we cut apart big program earlier with its segmentation, are beneficial to data and transmit, and the size of section is big or small similar to normal business data packet, can differently according to concrete business decide.
Then to dividing good data segment to handle, added paragraph header before each data segment, the section of comprising sequence number information in this paragraph header also comprises the information of whole file fragmentation in the paragraph header, in the process that data transmit, can be according to the next segmentation of the section sequence number information index of present segment.
Load this program to chip then, when loading, load piecemeal, guaranteeing has certain time interval between section and the section, and this time interval size is similar with the time interval of business data packet, and this also is the influence that brings for fear of bus contention.In this time interval, can come the control time at interval by this timing mechanism by a timing mechanism is set.Such as controlling by the timer on the HOST, arrive when the time one, then begin to load next segment file; This timing mechanism also can be controlled by the chip timer that is loaded, when the time then, the chip that is loaded sends message to HOST and requires to load next section, HOST begins to load next section program after receiving this message.
In the process that loads, can judge whether the loaded data section is legal by information such as paragraph header stage casing sequence numbers, whether continuous etc.
When the file fragmentation of desire loading all was loaded on the chip, the paragraph header of dismantling sign also reassembled into complete program file.Dismantling of this paragraph header sign can be determined according to the difference of actual conditions, can all dismantle after the loaded at whole program segmentings, also can dismantle while loading, load the paragraph header sign of this section program of promptly dismantling after one section program, like this after loading all program segments, directly make up and get final product.
After the success of whole procedure file load, send load document to HOST and load success message; Otherwise then reporting file loads failed message, and requires to reload.
In actual the use, this loads the transmission of success message, it might not be necessary step, promptly not necessarily leave no choice but report by successful loading messages, can also detect whether load success by modes such as inquiry registers, same reason, above-mentioned failed message, also the mode that not necessarily sends by message obtains.
In practical operation, can a counter be set according to each situation that loads failure, be used for writing down the number of times that reloads, if surpass certain threshold value, then stop to load, and report error message.One side produces loop error.Setting up of this threshold value can be grasped flexibly, also can change setting in the threshold value of reloading counter.
When the business model (comprising the size of business data packet, the transmission time interval of business data packet etc.) of chip array when changing, the load time of the size of the section of adjustment and section at interval thereupon.
The above just loads the process of a program, in actual applications, may need to load many programs, at this moment, can be according to said method segmentation of the present invention, loading, control, principle is identical.
See a concrete loading example below.
As shown in Figure 1, be a speech processes veneer scheme, can realize the packet voice communication.The chip array that this scheme is made up of a HOST, some voice process chip, converge logic and packet processing unit is formed.Wherein, chip array converges to by service bus and converges logic, HOST also have one with converge configuration and the loading interface that logic is connected.The voice packet of each pronounciation processing chip is delivered to by service bus and converges logic, is delivered to packet processing unit again; HOST loads chip array via converging logic by the configuration loading interface, and loading data also is to be delivered to each pronounciation processing chip by service bus.
The loading of present embodiment may further comprise the steps:
1. will need the program file section of being divided into that loads, and be divided into the program segment that every segment length is 300BYTES, with the G.711 speech data packet length of 30ms similar (240 BYTES), the section of not enough 300BYTES can be filled slack byte.
Increase paragraph header in each section then, its form is:
| Segment identification 8 bits | End-of-file identifies 1 bit | Section sequence number 16 bits | Section effective length 15 bits | CRC check 8 bits | Section content 1-294 byte | Byte of padding 0-293 byte |
Wherein:
Segment identification: 01111110
End-of-file sign: 0: non-end-of-file; 1: end-of-file
The section sequence number: the section sequence number of first of each file section is 0, increases by 1 successively later on.
CRC check; Use the CRC-8 check polynomial
Section content: the program file content that needs loading
If byte of padding: 0XFF is during less than 300 bytes, in order to fill.
2. load the primary control program of about 250 bytes of length before loading earlier, this primary control program carries program and loads configuration information needed, and mainly finishes control and message processing function to the process that loads.If primary control program loads successfully, then return primary control program and load success message, primary control program loads failed message and requirement is reloaded otherwise return.
3. according to section sequence number loading procedure piecemeal, and every 30ms loads one section.A timer is set in pronounciation processing chip, and every 30ms sends a message to HOST, sends next section when HOST detects this message.
4. the every reception of speech processes then judges according to segment identification, section sequence number, section effective length and CRC check whether this section loading is correct for one section, if correct, then feedback section loads success message; As mistake, then feedback section loads failed message.When HOST receives the loading success message, then continue to load next section; Otherwise reload the preceding paragraph.
5. speech processes judges whether loaded whole procedure file according to the end-of-file sign, if whole file load is correct, then feedback file loads success message; As mistake, then feedback file loads failed message.When HOST receives the file load success message, then continue to load next file; Otherwise reload a file.
6. behind the All Files loaded, the program that brings into operation, if operation is normal, then feedback process loads normal messages; As mistake, then feedback process loads failed message.When the HOST program that receives loads success message, then begin normal operation; Otherwise reload one time.
7. after the number of times that reloads that causes because of section loading, file load and procedure failure surpasses 3 times, then stop to load, and report error event message.
8. when chip array uses 5ms G.711 encoding and decoding speech is professional, the size of each file fragmentation is decided to be 50 bytes (G.711 speech data size 40 bytes are similar to 5ms), and revises a section effective length information; Section is loaded the interval become 5ms.
Program the be divided into section of the present invention by loading, by paragraph header stage casing each section of sequence number information identification index, the method that loads at interval each section one by one according to certain hour during loading procedure is avoided program loaded with traffic taking for a long time bus, eliminated the influence of program loading to newsletter, thereby the dynamic load of the program of realization, program can non-interrupting service communication when loading, and effect is very obvious.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
