Embodiment
Software is realized compatible method behind a kind of single board hardware change proposed by the invention, and it mainly may further comprise the steps: at first, be provided with on single plate hardware and change the plate sign, this sign is used to write down the current plate number of times that changes of described single plate hardware; Then, read and change the plate sign on the described single plate hardware, and from the single board software edition file, find corresponding software document according to changing the plate sign, be loaded on the described single plate hardware.
LTE Baseband Processing Unit BP with the NodeB of WCDMA (Wideband Code Division Multiple Access, wideband CDMA) is that example describes the present invention below.Above-mentioned LTE Baseband Processing Unit BP changes plate through 3 times, and three times the plate sign that changes is respectively that the software version file that changes the plate correspondence for 1,2,3, three times is respectively swbp1, swbp2, swbp3, and these three file sizes are respectively 1000byte, 1200byte, 1300byte.
When adopting method of the present invention, at first can in the hardware memory of LTE Baseband Processing Unit BP, preserve and change plate sign Flag, be used to write down the current plate number of times that changes of single plate hardware.Single plate hardware changes plate at every turn, all upgrades changing plate sign Flag, and it is as the unique sign that changes plate, as the foundation of carrying out software loading later on.For example, LTE Baseband Processing Unit BP obtains the BP1 plate through changing plate for the first time, and it changes plate sign Flag is 1, and corresponding software version is swbp1, and its size is 1000byte; LTE Baseband Processing Unit BP obtains the BP2 plate through changing plate for the second time, and it changes plate sign Flag is 2, and corresponding software version is swbp2, and its size is 1200byte; LTE Baseband Processing Unit BP obtains the BP3 plate through changing plate for the third time, and it changes plate sign Flag is 3, and corresponding software version is swbp3, and its size is 1300byte.It is compatible for above-mentioned BP1 plate, BP2 plate and BP3 plate can be realized when carrying out software loading, the unified single board software edition file swbpAll that makes of the present invention, comprising software version file swbp1, swbp2 and swbp3, and the one-to-one relationship that changes plate sign Flag and software version, arrive corresponding software version file according to the plate tag lookup that changes on the single plate hardware when being convenient to carry out software loading.
Above-mentioned single board software edition file swbpAll can adopt following dual mode:
One: described single board software edition file swbpAll adopts the form of database, sets up and change plate sign 1 (expression value be 1 change the plate sign), change plate sign 2 (expression value be 2 change the plate sign), changes plate sign 3 one-to-one relationship of (expression value be 3 change the plate sign) and software version file swbp1, swbp2 and swbp3.That is to say, described single plate hardware changes the pairing plate sign Flag, described single plate hardware of changing of plate at every turn and changes corresponding software version and the described one-to-one relationship that changes plate sign Flag and described software version behind the plate at every turn, can adopt the mode basis of tabling look-up to change the corresponding software version of plate tag lookup like this.
Its two: referring to Fig. 1, single board software edition file swbpAll is divided into file header and file content two parts, in file header, change at every turn that plate is pairing to change plate sign Flag and this changes the content size value of the pairing software document of plate sign, leave in successively in its continuous mark position according to the sequencing that changes plate, wherein, the content size value of described software version is placed on corresponding changing after the plate sign.As: can place successively in a plurality of flag bits of file header: change plate sign 1, change the corresponding software document of plate sign 1 veneer size ..., change plate sign N, change the size of the corresponding software document of plate sign N veneer;
Deposit the content of each version software file in the continuation address of file content successively according to the sequencing that changes plate, deposit successively as, file content part: change the corresponding software document content of plate sign 1 veneer ..., change the corresponding software document content of plate sign N veneer.Above-mentioned N is the natural number more than or equal to 1.
Certainly in file header part, what described single plate hardware can be deposited in the first place changes the plate total degree, and when the standard of comparison that stops as loading procedure according to this is convenient to judge when carrying out software loading termination process below to describe in detail in the concrete grammar step.
When adopting the above-mentioned second way to set up single board software edition file swbpAll,, when then making single board software edition file swbpAll, only above-mentioned N need be got 3 just passable because LTE Baseband Processing Unit BP has only changed plate three times.As shown in Figure 2, the concrete form following (according to 16 system forms) of the file header of the single board software edition file swbpAll of LTE Baseband Processing Unit BP part:
03 01 03E8 02 04B0 03 0514
The file content part is deposited successively: swbp1, swbp2, swbp3.
Like this, the BP single board software edition file swbpAll that changes behind the plate 3 times has comprised swbp1, swbp2, three softwares of swbp3 and has changed the plate sign.
When adopting the single board software edition file swbpAll form of above-mentioned form shown in Figure 1 that single plate hardware is carried out software loading, idiographic flow is as follows.
As shown in Figure 3, at first carry out the work of Board Power up program initialization, and read from single plate hardware (being the BP2 plate) and to change plate sign Flag, and from single board software edition file swbpAll, read the file header part; Carry out following software loading flow process then:
111, default address offset amount offset, and its initial value is composed is zero, i.e. offset=0; A default cyclic variable i, and the initial value of this variable i is composed is 1, i.e. i=1; And read among the single board software edition file swbpAll and to change plate total degree N in the file header;
112, judge that whether cyclic variable i is less than changing plate total degree N; Be that then execution in step 113; Not, then stop loading flow process, fault processing is carried out in the failure of expression load software then;
113, read in the file header of single board software edition file swbpAll i change plate sign (promptly changing plate sign i), and this indicate sizes values (promptly changing the size of the corresponding software document of plate sign i veneer) of pairing software document content;
114, judge in the described file header change on plate sign i and the described single plate hardware whether change plate sign Flag consistent; Be that then execution in step 115; Not, then execution in step 116;
115, the first address from the file content of single board software edition file begins, be offset described address offset amount offset backward, and read file content according to the sizes values of software document content in the file header that reads, obtain currently to change the pairing software document of plate number of times, and be loaded on the single plate hardware;
116, described address offset amount is superimposed with the sizes values (being the size that address offset amount offset=offset+ changes the corresponding software document of plate sign i veneer) of software version content in the file header that reads;
117, cyclic variable i is added 1, be repeated to step 112.Introduce a cyclic variable i in the said process, be used to write down cycle-index, and the plate total degree N that changes among itself and the single board software edition file swbpAll is compared, guaranteed the normal operation of loading procedure, determined the program termination time.
In the above-mentioned idiographic flow, if be example with the software loading process that changes for the second time the BP2 plate of plate, the single board hardware change sign Flag=2 that then reads, its step 111 specifically can be undertaken by following process to 117:
121, at first address offset amount offset is changed to 0, cyclic variable i is changed to 1, reads to change plate total degree N=3 in the single board software edition file swbpAll file header;
122, judge cyclic variable i less than 3, then carried out for 123 steps and handle.
123, read the sizes values that changes plate sign 1 and swbp1 in the file header (promptly 1000), judge change on plate sign 1 and the BP2 plate to change plate sign Flag unequal, then address offset amount offsett is added the file size 1000 of swbp1, carried out for 124 steps and handle;
124, cyclic variable i is added 1 (being i=2), judge cyclic variable i, then carried out for 125 steps and handle less than 3;
125, read the sizes values that changes plate sign 2 and swbp2 in the file header (promptly 1200), judge that change plate sign 2 equates with the plate sign Flag that changes on the BP2 plate, then the log file size equals the size 1200 of swbp2, the BP2 veneer from the file content of software version file partly then, be offset 1000 addresses backward, read size and be 1200 file content (just in time being the file content of swbp2), and it is loaded.What above-mentioned steps 121 to 125 was explained is a specific embodiment of above-mentioned steps 111 to 117.From above example, but the technical scheme that the present invention proposes not only has the board hardware change advantage of software version compatibility afterwards, can also reduce the advantage of the complexity of hardware version management.And the present invention not only is suitable for WCDMA base station system, the also hardware single board of suitable other communication systems.
Illustrating of above-mentioned each concrete steps is comparatively concrete, can not therefore think the restriction to scope of patent protection of the present invention, and scope of patent protection of the present invention should be as the criterion with claims.
