Disclosed in the present invention is are a method and apparatus for implementing chip correlation for multi-path search. The method comprises: writing chip data into a memory array according to the receiving time order of the chip data; reading the chip data, which correlation operation is needed to be carried out on within a current clock period, from the memory array according to a demand of the search; and grouping the chip data which is read out by predetermined grouping manner, and carrying out the correlation operation for each chip group in multiple chip groups and a pseudo-noise (PN) code sequence, wherein the multiple chip groups are obtained by the grouping; the chip data of each chip group in the multiple chip groups are multiple chip data which are received consecutively, the number of the chip data in each chip group is equal to each other, and the second chip data of each chip group is the first chip data in the next chip group according to the receiving time order of the chip data. By way of the present invention, correlation operation with high correlation order can be completed using a small amount of memories, thus memory resources are effectively saved, the costs and hardware complexity are reduced; and the flexibility of correlation operation can be improved; in addition, the purpose of seamless handover can be achieved. |
