Abstract

[0059] The first embodiment of the present invention provides a vector sorting device, see below. Figure 1 ,include

[0063] The merging unit includes an element merging unit and a vector fragment merging unit.
[0064] The selection unit selects the vector segment according to the sorting status of the vector segment, so that the elements in the sorted vector segment require fewer comparisons than the elements in the unsorted vector segment.
[0065] In some embodiments, the vector fragment selection unit is used to perform fragment selection in a sorting instruction on the input vector. The sorting instruction is a first sorting instruction, a second sorting instruction, or a third sorting instruction that matches the element type of the input vector. The first sorting instruction is used to establish a sort between data vectors and index vectors; the second sorting instruction is used to establish a sort between data vectors; and the third sorting instruction is used to establish a sort between index vectors.
[0066] See Figure 2 In some embodiments, the execution of the first sorting instruction includes the following steps:
[0067] The input vectors are data vector vds0 and index vector vds1. The data vector vds0 is sorted by the first operation instruction op0, the second operation instruction op1, or the third operation instruction op2 to obtain the sorted data vector change info.
[0068] Based on the sorted data vector change info, the index vector vds1 is sorted to obtain the sorted index vector;
[0069] Store the sorted data vector change info back as the output data vector vds0, and store the sorted index vector back to obtain the output index vector vds1.
[0070] See Figure 3 In some embodiments, the execution of the second sorting instruction includes the following steps:
[0071] The input vectors are the first data vector vds1 and the second data vector vds2. Select the first segment vds1.hi of the first data vector vds1 and the second segment vds1.lo of the second data vector vds0.
[0072] Merge the first segment vds1.hi of the first data vector vds1 with the second segment vds1.lo of the second data vector vds0;
[0073] The first segment vds1.hi of the merged first data vector and the second segment vds0.lo of the second data vector are sorted using the first operation instruction op0, the second operation instruction op1, or the third operation instruction op2 to obtain the sorted data vector change info.
[0074] At the same time, the first segment vds1.hi.rank of the sorted data vector is merged with the second segment vds1.lo of the first data vector, and the first segment vds0.hi of the second data vector is merged with the second segment vds0.lo.rank of the sorted data vector.

[0076] See Figure 4 In some embodiments, the execution of the third sorting instruction includes the following steps:
[0077] The input vectors are the first index vector vds1 and the second index vector vds2. Select the first segment vds1.hi of the first index vector vds1 and the second segment vds1.lo of the second index vector vds0.
[0078] Merge the first segment vds1.hi of the first index vector vds1 with the second segment vds1.lo of the second index vector vds0;
[0079] Based on the sorting information of the sorting data vector change info saved in the prior instruction, sort the first segment vds1.hi of the merged first index vector vds1 and the second segment vds1.lo of the second index vector vds0;
[0080] Merge the first segment of the sorted index vector vds1.hi.rank with the second segment of the first index vector vds1.lo, and merge the first segment of the second index vector vds0.hi with the second segment of the sorted index vector vds0.lo.rank.
[0081] The number of elements contained in the first segment vds1.hi of the first index vector is equal to the number of elements contained in the second segment vds1.lo of the first index vector, and the number of elements contained in the first segment vds0.hi of the second index vector is equal to the number of elements contained in the second segment vds0.lo of the second index vector.
[0082] In some embodiments, the element selection unit is used to select vector segments between the first operation instruction op0 and / or the second operation instruction op1 and / or the third operation instruction op2 based on the vector segment selected by the vector segment selection unit.
[0083] See Figure 5The first operation instruction op0 is used to sequentially establish the sorting between two adjacent elements; the second operation instruction op1 is used to sequentially establish the sorting between two adjacent elements after excluding the first and last elements; the third operation instruction op2 is used to sequentially select one element in the first half and the second half of the vector, respectively, and establish the sorting of the two elements selected in the first half and the second half of the vector.
[0084] In some embodiments, the comparison and exchange unit includes a comparison unit and an exchange unit. The comparison unit compares the size between two elements, and the exchange unit, according to ascending or descending sorting instructions and based on the size between the two elements output by the comparison unit, exchanges or maintains the order of the two compared elements.
[0085] In some embodiments, the element merging unit is used to place the sorted elements back into segments of a vector. The segment merging unit is used to merge segments into a vector.
[0086] In some embodiments, the vector sorting device further includes a register R, which is used to store data that needs to be temporarily placed during the execution of the vector sorting device.
[0087] A second embodiment of the present invention provides a vector sorting method, see below. Figure 6 It includes the following steps:
[0088] The segment selection in the sorting instructions is executed on input vector 1 and input vector 2. The sorting instructions are the instructions that match the element type of the input vectors from the first, second, and third sorting instructions. The first sorting instruction is used to establish the sorting between data vectors and index vectors; the second sorting instruction is used to establish the sorting between data vectors; and the third sorting instruction is used to establish the sorting between index vectors.
[0089] In some embodiments, the execution of the first sorting instruction includes the following steps:
[0090] The input vectors are data vector vds0 and index vector vds1. The data vector vds0 is sorted by the first operation instruction op0, the second operation instruction op1, or the third operation instruction op2 to obtain the sorted data vector change info.
[0091] Based on the sorted data vector change info, the index vector vds1 is sorted to obtain the sorted index vector;
[0092] Store the sorted data vector change info back as the output data vector vds0, and store the sorted index vector back to obtain the output index vector vds1.
[0093] In some embodiments, the execution of the second sorting instruction includes the following steps:
[0094] The input vectors are the first data vector vds1 and the second data vector vds2. Select the first segment vds1.hi of the first data vector vds1 and the second segment vds1.lo of the second data vector vds0.
[0095] Merge the first segment vds1.hi of the first data vector vds1 with the second segment vds1.lo of the second data vector vds0;
[0096] The first segment vds1.hi of the merged first data vector and the second segment vds0.lo of the second data vector are sorted using the first operation instruction op0, the second operation instruction op1, or the third operation instruction op2 to obtain the sorted data vector change info.
[0097] At the same time, the first segment vds1.hi.rank of the sorted data vector is merged with the second segment vds1.lo of the first data vector, and the first segment vds0.hi of the second data vector is merged with the second segment vds0.lo.rank of the sorted data vector.
[0098] The number of elements contained in the first segment vds1.hi of the first data vector is equal to the number of elements contained in the second segment vds1.lo of the first data vector, and the number of elements contained in the first segment vds0.hi of the second data vector is equal to the number of elements contained in the second segment vds0.lo of the second data vector.
[0099] In some embodiments, the execution of the third sorting instruction includes the following steps:
[0100] The input vectors are the first index vector vds1 and the second index vector vds2. Select the first segment vds1.hi of the first index vector vds1 and the second segment vds1.lo of the second index vector vds0.
[0101] Merge the first segment vds1.hi of the first index vector vds1 with the second segment vds1.lo of the second index vector vds0;
[0102] Based on the sorting information of the sorting data vector change info saved in the prior instruction, sort the first segment vds1.hi of the merged first index vector vds1 and the second segment vds1.lo of the second index vector vds0;
[0103] Merge the first segment of the sorted index vector vds1.hi.rank with the second segment of the first index vector vds1.lo, and merge the first segment of the second index vector vds0.hi with the second segment of the sorted index vector vds0.lo.rank.
[0104] The number of elements contained in the first segment vds1.hi of the first index vector is equal to the number of elements contained in the second segment vds1.lo of the first index vector, and the number of elements contained in the first segment vds0.hi of the second index vector is equal to the number of elements contained in the second segment vds0.lo of the second index vector.
[0105] Element selection is performed on the split and selected vector segments. In some embodiments, the element selection unit is used to select vector segments between the first operation instruction op0 and / or the second operation instruction op1 and / or the third operation instruction op2 based on the split and selected vector segments by the vector segment selection unit.
[0106] The first operation instruction op0 is used to sequentially establish the sorting between two adjacent elements; the second operation instruction op1 is used to sequentially establish the sorting between two adjacent elements after excluding the first and last elements; the third operation instruction op2 is used to sequentially select one element in the first half and the second half of the vector, respectively, and establish the sorting of the two elements selected in the first half and the second half of the vector.
[0107] In some embodiments, to keep unselected data in sync with selected data and avoid timing errors, a register is also set up during the element selection process to place the selected element.
[0108] Compare the size between the two selected elements, and swap or maintain the order of the two compared elements according to the ascending or descending sorting instructions.
[0109] The sorted elements are placed back into the segments of the vector, and the segments are merged into output vector 1 and output vector 2.
[0110] In one embodiment, see Figure 7 The input vectors vds0 and vds1 are both completely unsorted and irregular data vectors. After element selection, N completely unsorted and irregular data are obtained. After looping through the first operation instruction op0 N / 2 times and the second operation instruction op1 N / 2 times, the N completely unsorted and irregular data are completely sorted and stored back into the vector as the output vector.
[0111] In one embodiment, see Figure 8The input vectors vds0 and vds1 are the first half of the data vectors, which are already sorted and represent regular data vectors. The second half is the remaining unsorted data vector. During the sorting process, the first and second halves are merged and then sorted. The sorting process sequentially goes through one third operation instruction op2, one second operation instruction op1, and repeats the first operation instruction op0 and the second operation instruction op1 (N / 4-1) times, completing the complete sorting of N data vectors and storing them back into the output vector.
[0112] For vectors with pre-existing patterns that have already been sorted, this embodiment, based on the regularity of the input vector, performs reasonable slicing and integration of the input vector and adjusts the operation instructions, so that sorting can be completed with a small number of operation instructions, avoiding repeated sorting of regular segments within the vector and improving vector sorting efficiency.

[0114] Those skilled in the art will understand that all or part of the processes in the methods of the above embodiments can be implemented by a computer program instructing related hardware. The program can be stored in a computer-readable storage medium, and when the program is executed, it can include the processes of the embodiments of the methods described above.
[0115] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of the present invention.
