Detailed description of the invention
2 × 2 two-dimensional process element array PE0-PE3(Fig. 1), these 4 processing units interconnect the two of composition 2 × 2 by neighbour
Dimension Processor Array.
Macro block 1-16(Fig. 2), English Macroblock, is a basic conception in video coding technique.Compile at video
In Ma, a coded image is commonly divided into some macro blocks composition, and a macro block is by a luminance pixel block and two added
Chroma pixel block forms.In general, luminance block is the block of pixels of 16 × 16 sizes, and the size of two colourity block of image pixels
Depending on the sample format of its image, such as: for YUV420 sampled images, chrominance block is the block of pixels of 8 × 8 sizes.Each
In image, some macro blocks are arranged sheet of form, and video coding algorithm is in units of macro block, and macro block encodes one by one, group
It is made into continuous print video code flow.
In MVC image be the macro block with 16 × 16 sizes as unit, each macro block is made up of 16 4 × 4 size block,
It is likely to occur blocking effect, so needing each border of macro block is filtered between each two adjacent block.For under yuv format
Macro block, its macro block is made up of luminance component Y and chromatic component U/V.Macroblock boundaries (Fig. 3) is divided into vertical boundary and horizontal sides
Boundary, left side is luminance block (data block that luminance component is corresponding), and right side is chrominance block (data block that chromatic component is corresponding).V0-
V3 is the vertical boundary of luminance block, and H0-H3 is the horizontal boundary of luminance block, and pixel to be filtered is macroblock boundaries often row both sides
8 pixels (p3, p2, p1, p0, q0, q1, q2, q3).In like manner, V0, the V1 on right side are the vertical boundaries of chrominance block, H1, H2
Being the horizontal boundary of chrominance block, same, pixel to be filtered is 8 pixels of Mei Hang both sides, chrominance block border.Deblocking is filtered
Ripple algorithm is exactly to be filtered calculating to 8 pixels of macroblock boundaries often row every time.
The step that implements of the present invention is:
A: luminance component Y is filtered (Fig. 4, in figure, a-l is filter sequence), on the left of PE0 loading processing on the left of luminance block R0(
4 × 4 adjacent data blocks, belong to another macro block) and the first row of right side luminance block 1, the second row, the third line, fourth line pixel；
4 × 4 data blocks adjacent on the left of luminance block R1(on the left of PE1 loading processing, belong to another macro block) and the first of right side luminance block 5
Row, the second row, the third line, fourth line pixel；4 × 4 data blocks adjacent on the left of luminance block R2(on the left of PE2 loading processing, belong to
Another macro block) and the first row of right side luminance block 9, the second row, the third line, fourth line pixel；Luminance block on the left of PE3 loading processing
4 × 4 data blocks adjacent on the left of R3(, belong to another macro block) and the first row of right side luminance block 13, the second row, the third line,
Four row pixels.After having loaded etc. data, PE0-PE3 carries out parallel filtering computing according to the data loaded respectively, to be filtered
After computing completes, the filtering to the vertical boundary V0 of luminance component calculates complete.
B: to chromatic component U (Fig. 5, in figure, b-k is filter sequence), V(Fig. 6, in figure, b-k is filter sequence) it is filtered
Process.The most also being 4 PE parallel processings, PE0-PE1 processes the vertical boundary of chromatic component U；PE2-PE3 processes colourity and divides
The vertical boundary of amount V.And in whole filtering calculates, for processing U, the PE of V component immobilizes, the advantage of do so
It is: the data process to chromatic component U, V is completely unrelated, can separately process, increase degree of parallelism；And process colourity and divide
Having data to be correlated with between 2 corresponding PE of amount U or V, such as PE0 may use any one data in PE1, this
Sample, it is necessary to make PE0-PE1, PE2-PE3 fix one U of process or the data of V component, communicates between data to facilitate.
The chrominance block processing procedure of component U: with PE0 process on the left of chrominance block R0 and the first row of right chroma block 1, second
Row, the third line, fourth line pixel；PE1 process on the left of chrominance block R1 and the first row of right chroma block 3, the second row, the third line,
Fourth line pixel.The chrominance block processing procedure of component V: PE2 process on the left of chrominance block R0 and the first row of right chroma block 1, the
Two row, the third line, fourth line pixel；PE3 process on the left of chrominance block R1 and the first row of right chroma block 3, the second row, the 3rd
Row, fourth line pixel.It is all parallel that PE0-PE3 filtering calculates, and now, their colourity filtering flag position chromaFlag is
It is 1, and need not recalculate BS value, but the BS value of corresponding brightness component directly is replicated.Treat that 4 PE have calculated
Cheng Hou, just completes the filtering of each self-corresponding vertical boundary V0 of chromatic component U, V.
C: for luminance block (1,5,9,13), use data the most processed separately for PE0-PE3 in a, it is not necessary to again
Load.So now, PE0-PE3 only need to load right side block 2, the pixel of 6,10,14 respectively.PE0 loads right side respectively and works as
The first row of front piece 2, the second row, the third line, fourth line pixel；PE1 load on the right side of the first row of current block 6, the second row, the 3rd
Row, fourth line pixel；The first row of current block 10, the second row, the third line, fourth line pixel on the right side of PE2 loading；PE3 loads the right side
The first row of side current block 14, the second row, the third line, fourth line pixel.After having loaded etc. data, PE0-PE3 basis respectively
The data loaded are filtered computing, and after computing to be filtered completes, the filtering to the vertical boundary V1 of luminance component has calculated
Finish.
D: in like manner, PE0-PE3 load the data corresponding with processing vertical boundary V2 according to the mode identical with c, and advance
Row filtering calculates.After 4 PE have filtered, the filtering just completing vertical boundary V2 calculates.
E: now need the vertical boundary V1 of chromatic component U, V is filtered.Now, the chrominance block 1,3 of V, U component needs
The data wanted are the data in b after PE0-PE3 process, so there being these data in PE0-PE3 the most respectively.The most only need
PE0-PE1 loads each row of data of U component chrominance block 2,4 respectively, and PE2-PE3 loads each row of data of the block 2,4 of V i.e. respectively
Can.Now, after data loaded, 4 PE just can carry out parallel filtering calculating, and the operation between them is independent of each other.Treat 4
Individual PE calculates complete, i.e. completes the filtering of the vertical boundary V1 of U, V.
F: same, according to the processing mode identical with c, loads the vertical boundary V3 of luminance component Y respectively by PE0-PE3
Corresponding data, are filtered calculating parallel.After 4 PE have filtered, the filtering just completing vertical boundary V3 calculates.
G: now, the vertical filtering to macro block is complete, and needs to be filtered the horizontal boundary of macro block.PE0 process
Adjacent 4 × 4 data blocks on the upside of luminance block T0(of upside, belong to another macro block) and the first row of downside luminance block 1, secondary series,
3rd row, the 4th row pixel；4 × 4 data blocks adjacent on the upside of luminance block T1(on the upside of PE1 process, belong to another macro block) and under
The first row of side luminance block 2, secondary series, the 3rd row, the 4th row pixel；PE2 process on the upside of on the upside of luminance block T2(adjacent 4 × 4
Data block, belongs to another macro block) and the first row of downside luminance block 3, secondary series, the 3rd row, the 4th row pixel；In PE3 process
4 × 4 data blocks adjacent on the upside of luminance block T3(of side, belong to another macro block) and the first row of downside luminance block 4, secondary series,
Three row, the 4th row pixel.
Now, when processing brightness border H0, PE0 only need to load the data of luminance block T0 and can calculate, and
PE1, PE2, PE3 need to load luminance block T1, the data of T2, T3 and luminance block 2 respectively, block 3, the data of block 4 just can be carried out also
Row calculates.Luminance block 2, block 3, the value of block 4 all leave in PE0, so these numerical value can be read by shared depositor.When
The desired data of PE0-PE3 can be carried out concurrent working after being ready to, and then completes the filter to luminance component horizontal boundary H0
Ripple.
The vertical boundary filtering of h: chromatic component U, V is complete.Need its horizontal boundary is filtered.Identical,
Still it is filtered processing to chromatic component U with PE0-PE1；Chromatic component V is filtered processing by PE2-PE3.Now, PE0-
PE1 only need to load the T0 first row data to the 4th row, other 4 number corresponding needed for then obtaining from PE0-PE1 respectively
According to.And PE2-PE3 need to load the T0 first row data to the 4th row respectively, and from PE0-PE1, obtain other 4 numbers
According to.For processing the PE2-PE3 of chromatic component V, it is also such that its data load.After DSR, just can hold parallel
Row filtering, completes the filtering of the horizontal boundary H0 to chromatic component U, V.

Information, so just can carry out horizontal boundary filtering after needing the vertical boundary filtering of whole macro block to be done；2 × 2 two-dimensional process units
Array (PE0-PE3) is respectively to 4 groups of vertical boundary (H0) both sides of luminance component Y, often 4 subgroup totally 16 subgroups of group, often son
Organize 8 pixels (p3, p2, p1, p0, q0, q1, q2, q3) and carry out data loading, wait data recordation to complete, respectively according to added
The data carried carry out parallel filtering computing, and after computing to be filtered completes, the filtering to the border (H0) of luminance component Y has calculated
Finish；2 × 2 two-dimensional process element array (PE0-PE1) are respectively to 2 groups of vertical boundary (H0) both sides of chromatic component U, often group 4
Subgroup totally 8 subgroups, 8 pixels (p3, p2, p1, p0, q0, q1, q2, q3) of every subgroup carry out data loading, meanwhile, 2 ×
2 two-dimensional process element array (PE2-PE3) are respectively to 2 groups of vertical boundary (H0) both sides of chromatic component V, often 4 subgroups of group totally 8
Subgroup, 8 pixels (p3, p2, p1, p0, q0, q1, q2, q3) of every subgroup carry out data loading, wait data recordation to complete, respectively
Parallel filtering calculating is carried out, the filtering after computing to be filtered completes, to the border (H0) of chromatic component according to described data
Calculating complete, during whole, 2 × 2 two-dimensional process element array (PE0-PE1) are for the BORDER PROCESSING to chromatic component U, and 2
× 2 two-dimensional process element array (PE2-PE3) are for the BORDER PROCESSING to chromatic component V, and immobilize；When processing luminance component
During vertical boundary (H1) of Y, due in border (H0) processing procedure to border (H1) upside, i.e. border (H0) downside, 4
The data of individual block (1,2,3,4) load, so only need to load the pixel of 4 blocks (5,6,7,8) of downside, border (H1)
Point, and border (H1) both sides 16 subgroup, 8 pixels of every subgroup are carried out parallel filtering calculating, after computing to be filtered completes, right
The filtering on the border (H1) of luminance component calculates complete；When processing vertical boundary (H2) of luminance component Y, due on border
(H1) to border (H2) upside in processing procedure, i.e. border (H1) downside, the data of 4 blocks (5,6,7,8) load,
So the pixel of 4 blocks (9,10,11,12) of downside, border (H1) only need to be loaded, and to border (H1) both sides 16 subgroup, every
8 pixels of subgroup carry out parallel filtering calculating, and after computing to be filtered completes, the filtering to the border (H1) of luminance component calculates
Complete；Equally when processing chromatic component U, V respective vertical boundary (H1), only need to load 2 blocks of its (H1) downside respectively
The data of the pixel of (3,4), have loaded etc. data, the corresponding processing elements (PE) 8 subgroups to boundaries on either side, every subgroup
8 pixels carry out parallel filtering calculating, and after calculating to be filtered completes, the border H1 filtering just completing component U, V is complete；With
Reason, remaining border of luminance component Y (H3) is filtered calculating according to the processing mode of border (H1).
