Figure 7: Three data pattern settings: (a) “R2C2”: there are 2×2 blocks (2 row
clusters and 2 column clusters), each of which contains 2×2 cells, thus the data
size is 4×4. (b) “2*R2C2”: the block size is doubled in the “R2C2” setting, thus the
data size is 8×8. (c) “R4C4”: there are 4×4 blocks (4 row clusters and 4 column
clusters), each of which contains 2×2 cells, thus the data size is 8×8. |
