Embodiment
Hereinafter with reference to accompanying drawing, also describe the present invention in detail in conjunction with the embodiments.It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.
Consider in implementation process, the wire rate of Serdes is normally unknown, need auto-negotiation mode to mate, but the various rate frame forms of the upper transmission of Serdes is normally known.Therefore the present embodiment is unknown at the wire rate of Serdes, but under the condition that on Serdes, the various rate frame forms of transmission are known, the method for the rate consulation carrying out and device.The method is not confined to the agreement of some standards, such as remote radio unit (RRU) (Remote Radio Unit, referred to as RRU) and base station baseband unit (Baseband Unit, referred to as BBU) between interface (Interface between the RRU and the BBU, referred to as IR), CPRI, open base station architecture tissue (Open Base Station Standard Initiative, referred to as OBSAI) etc., can be also user-defined frame format.It is consistent with high speed serialization speed that the method can complete Serdes speed fast, correctly receives the function of data, has short, the feature such as reliability is high, implementation complexity is low of time.
A kind of Serdes speed matching method is provided in the present embodiment, and Fig. 1 is that as shown in Figure 1, the method comprises the steps: according to the flow chart of the Serdes speed matching method of the embodiment of the present invention
Step S102, is Serdes configuration the first stringization/speed of unstringing, and with this first stringization/speed of unstringing string/unstring;
Step S104, judges whether the output data of the Serdes synchronization parameter corresponding with the string of the configuration/speed of unstringing mates;
Step S106, judgment result is that be in the situation that, determines that the string/speed of unstringing of configuration is identical with the input rate of Serdes.
The present embodiment passes through above-mentioned steps, the output data of Serdes are mated with the corresponding synchronization parameter of the string/speed of unstringing of configuration, due to only in the situation that the input rate of Serdes and the string of the configuration/speed of unstringing is identical, the output data of Serdes could be identical with the normal output of the string/speed of unstringing of above-mentioned configuration, in this case, synchronization parameter corresponding to the output data of Serdes and the string of the configuration/speed of unstringing just can mate.Therefore, in the situation that the output data of Serdes are mated with the corresponding synchronization parameter of the string of the configuration/speed of unstringing, illustrate that the input rate of Serdes is identical with the string of the configuration/speed of unstringing, thereby obtained the input rate of Serdes.Which can be used in wire rate the unknown of Serdes, but carry out rate consulation under the known condition of the various rate frame forms of the upper transmission of Serdes, solved in correlation technique the problem that the mode for the wire rate auto-negotiation of Serdes can not satisfy the demands, can complete fast the requirement of Serdes speed auto-negotiation, implementation complexity is low.
Preferably, in the situation that step S104 the determination result is NO, string/the speed of unstringing of proof configuration is not identical with the input rate of Serdes, now, can configure the second string/speed of unstringing for Serdes, and rejudge the output data of the Serdes synchronization parameter corresponding with the string of the configuration/speed of unstringing and whether mate, wherein, this second stringization/speed of unstringing and the first stringization/speed of unstringing is unequal.In this way, can in the incorrect situation of the string/speed of unstringing of configuration, re-start the configuration of the stringization/speed of unstringing, thereby can get the input rate of correct Serdes, which reliability is high.It should be noted that, above-mentioned " first " " second " only described for convenient, not as the restriction to order priority or specific meanings.
Preferably, incorrect in the first string/speed of unstringing, in the situation that need to reconfigure, can be by the rate set setting in advance incompatible above-mentioned the second stringization/speed of unstringing of choosing, this second stringization/speed of unstringing is different from the first stringization/speed of unstringing.In this way, dwindle the speed range of choice while reconfiguring stringization/unstring speed, therefore shortened negotiation time.The set-up mode of this speed set has a variety of, and for example, speed set can be user oneself definition, can be the full rate set that current agreement is supported, or can be also the speed set that starting equipment is supported.The mode of choosing the second string/speed of unstringing from speed set can be random, also can choose according to user-defined order, for example, can choose from low to high or from high to low.
As a kind of preferred implementation, judge that the mode whether the output data of the Serdes synchronization parameter corresponding with the string of the configuration/speed of unstringing mate can be undertaken by the sync mark in output data.For example, can be according to the sync mark in the output data of the corresponding duration detection of the string/speed of unstringing of configuration Serdes; In the situation that sync mark is mated with duration, can determine that the output data of the Serdes synchronization parameter corresponding with the string of the configuration/speed of unstringing matches; In sync mark and the unmatched situation of duration, can determine that the output data of the Serdes synchronization parameter corresponding with the string of the configuration/speed of unstringing do not mate.Whether judgement output data mate with synchronization parameter in this way, easy operating, and realizability is strong.
Whether preferably, can detect by the mode of timer sync mark mates with duration.Particularly, can judge when timer corresponding to above-mentioned duration overflows, default sync mark whether be detected, and/or whether accumulative total misdata does not surpass predetermined threshold value; Judgment result is that be in the situation that, can determine that sync mark mates with duration; In the situation that the determination result is NO, can determine that sync mark do not mate with duration.
Preferably, after definite sync mark is mated with duration, prove that the input data of current Serdes are identical with the string of the configuration/speed of unstringing, now, can be again according to the sync mark in the output data of the corresponding duration detection of the string/speed of unstringing of configuration Serdes, for example, can be by timer zero clearing corresponding to above-mentioned duration.In this way, in the time of can changing in the input data of Serdes, carry out rapidly auto-negotiation next time, compare in correlation technique and just only send normal data flow after having consulted, do not send the mode of certain code word, can complete more quickly the auto-negotiation of Serdes speed.
In addition, as a kind of preferred implementation, in the situation that the input data of current Serdes are identical with the string of the configuration/speed of unstringing, can also directly the string configuring/speed of unstringing be applied in to follow-up local data processing module, for example, in local parallel data processing module, thereby can carry out local data processing according to the string/speed of unstringing of configuration.In this way, in local data processing module, just can save the function of carrying out auto-negotiation with the output speed of Serdes, save logical resource.
