The subsampler partitions the frame into windows using the size, count, and starting location parameters shown on the left in Figure 6-69. Each window is further sampled down to a set of 2 × 2 blocks. The horizontal and vertical distances between the start of blocks within a window is programmable using the parameters shown on the right in Figure 6-69.
Figure 6-69 RAWFE H3A AE/AWB Window ConfigurationsTable 6-122 lists the bit fields that configure the window and block sizes, counts, and starting positions.
| Bit Field | Bit Width | Description |

| VISS_RAWFE_H3A_AEWWIN1[31:24] WINH | 7 | Window height (in lines) |
| VISS_RAWFE_H3A_AEWWIN1[5:0] WINHC | 6 | Window count for horizontal direction |
| VISS_RAWFE_H3A_AEWWIN1[12:6] WINVC | 7 | Window count for vertical direction |
| VISS_RAWFE_H3A_AEWINSTART[11:0] WINSH | 12 | Window start position H |
| VISS_RAWFE_H3A_AEWINSTART[27:16] WINSV | 12 | Window start position V |
| VISS_RAWFE_H3A_AEWSUBWIN[3:0] AEWINCH | 4 | Horizontal distance between subsamples |
| VISS_RAWFE_H3A_AEWSUBWIN[11:8] AEWINCV | 4 | Vertical distance between subsamples |
