Embodiment
The embodiment of the present invention provides a kind of data processing method and device, in order to realize, according to bus bandwidth, adjust in real time the data processing rate of the unit in RAKE receiver, thereby realize the Dynamic Matching of the transmission rate of each unit in bus actual bandwidth and RAKE receiver.
The embodiment of the present invention relates to 3-G (Generation Three mobile communication system), specifically, relates to the multi-path demodulation of Adaptable System bus bandwidth and the hardware resource management scheme of MRC in a kind of WCDMA band processing system.
Referring to Fig. 2, in table, the 2nd column data provides the interface transmission symbol speed between multi-path demodulation unit and MRC unit, and spreading factor SF, multipath number N, clock frequency F1(are the minimum interval of transmission symbol between multi-path demodulation unit and MRC unit) relation.As can be seen from the table, if the multipath number that band processing system is supported is more, the excursion of the interface transmission symbol speed between multi-path demodulation unit and MRC unit is larger, and hardware must can be processed large-scale rate variation, tackle paroxysmal two-forty, guarantee the stability of system.
In table shown in Fig. 2, the 3rd column data has provided the interface transmission symbol speed between multipath merge cells and bus in MRC unit, with the relation of SF, N, F1.Equally, as can be seen from the table, also there is paroxysmal two-forty problem in the interface transmission symbol speed between multipath merge cells and bus.Suppose bus working clock frequency F2, hardware is when design, and requiring bus coideal symbol transmission speed is that bus optimum wideband is 32F2.
Interface transmission rate in comparison diagram 1 between each unit, can find out, when clock F1=F2, can meet the demands in the ideal case, and hardware can stream treatment.But, in actual applications, because the factors such as the arbitration of bus multi-source, external cache unit readwrite bandwidth can affect the actual bandwidth of bus, actual bandwidth relative ideal bandwidth can decay to some extent, the multipath symbol that is transferred to so MRC unit from multi-path demodulation unit there will be accumulation, suppose that bus bandwidth decay factor is a, in the table shown in Fig. 2, the 4th column data provides the relation of multipath symbol accumulation rate and SF, N, a, F1, F2.
Real system is very high to the data integrity of multi-path demodulation, multipath assembling section and requirement of real-time, and the estimation difficulty of bus bandwidth decay factor a is large, this has brought challenge to the estimation multipath data volume that symbol is piled up, the size of piling up symbol data amount directly has influence on the spatial cache that MRC unit is opened up, if it is too little that spatial cache arranges, easily cause symbol data to be lost, arrange and too greatly waste hardware resource, increase the area of circuit.If reduce accumulation rate by improving the mode of bus working clock frequency F2, can in design, introduce different clock-domains, in design, need to increase the processing of cross clock domain, increased the complexity of design.
In addition, between MRC unit and symbol level processing unit, be the mode of length-specific memory space in external cache unit of reading and writing by circulation, realize the transmission of user data.In the local uneven situation of bus actual bandwidth, if MRC processing speed is higher than the processing speed of symbol level processing unit, the mode of this circulation read-write can cause the problem of the data that data cover symbol level processing unit that MRC unit is write do not read.
Therefore, in order to realize the Dynamic Matching of the transmission rate of bus actual bandwidth and each unit of RAKE receiver system.The technical scheme that the embodiment of the present invention provides, Real-Time Monitoring bus bandwidth is also controlled multi-path demodulation and MRC cell processing speed according to monitoring result, reach the Dynamic Matching that maintains transmission rate between each unit interface of RAKE receiver system, guarantee that upstream data service speed is not restricted by hardware resource.

Take minimum demodulating task as unit, antenna data is carried out to multi-path demodulation.
Preferably, the method also comprises:
The multipath symbol that multi-path demodulation is obtained carries out multipath merging, obtains and buffer memory multipath merged data;
When the multipath merged data amount of buffer memory surpasses default first threshold, stop antenna data carrying out multi-path demodulation.
Preferably, the method also comprises:
When obtaining same user's the multipath merged data of all RAKE of same Transmission Time Interval TTI, many RAKE data that buffer memory is corresponding with this user merge task;

Preferably, the method also comprises:
When many RAKE of buffer memory data merging task surpasses the 3rd default threshold value, stop antenna data carrying out multi-path demodulation.
That is to say, preferably, step S102 is: when the antenna data amount of obtaining meets multi-path demodulation demand, and, the multipath merged data amount of current cache does not surpass default first threshold, and, when many RAKE merging tasks of current cache do not surpass the 3rd default threshold value, antenna data is carried out to multi-path demodulation.

In MRC dynamic management unit, multipath merge cells receives the multipath symbol from the output of multi-path demodulation dispatch unit, completing channel compensation and multipath merges, merge symbol buffer unit and be responsible for buffer memory multipath merged data, and to outside buffer unit, initiate write data requests by bus, when its write request of external cache cell response, just corresponding data is sent.
The memory space of buffer memory multipath merged data is arranged to rational threshold value, merge first threshold default in symbol buffer unit, for example, suppose that storage size is L, first threshold is preset as to 1.5 times of k time slot data volume that L deducts spreading factor 2*2.When buffer data size surpasses first threshold, feed back flow control information to bus interface and monitoring means.When all RAKE data of the complete user's of hardware acquisition a TTI, RAKE merging task is cached to many RAKE and merges task buffer unit, and read address (externally data address during read data in buffer unit) according to the symbol level of symbol level processing unit feedback, judge whether that allowing to carry out many RAKE merges task, when the difference of reading address when the write address of MRC unit (data address while externally writing data in buffer unit) and symbol level is less than default Second Threshold, do not allow to carry out many RAKE and merge task, wherein, described Second Threshold predeterminable for spreading factor be 2*2+2*4 and the unique user symbol data amount that is modulated to 16QAM mode 1 times, 1.5 times or 2 times.If allow to carry out many RAKE, merge task, by many RAKE merge cells, by bus, from external cache unit, read the symbol of corresponding RAKE, complete many RAKE and merge, and amalgamation result is write in external cache unit.When many RAKE of buffer memory merging task surpasses the 3rd default threshold value, many RAKE merge buffer unit feedback flow control information to bus interface and monitoring means, wherein, described the 3rd threshold value can be supported number of users setting according to system, for example for example be set to the 80%(of system support number of users, system supports that number of users is at 100 o'clock, and the 3rd threshold value is 80).
The operation that bus interface and monitoring means are carried out comprises: the read-write operation of bus; Realize the read and write access of each unit to outside buffer unit in embodiment of the present invention device; Receive the flow control information that merges symbol buffer unit and many RAKE merging task buffer unit, and feed back to multi-path demodulation dispatch unit, reach flow control object, the speed of each interface of system realizes Dynamic Matching.
