Description
Base address byte offset DMA #3
Bits define pixel offset within multi pixel 64-bit words (e.g., a 16-bit
pixel can be placed on any 16-bit boundary).
Base address DMA #4
Used depending on PFU_BAMODE setting.
Base address DMA #5
Used depending on PFU_BAMODE setting.
Base address DMA #6
Used depending on PFU_BAMODE setting.
Phase mode
Disable line length cropping
Chroma sample re-sequence
(Used for striped scaling tasks in 4:2:x transposed mode if stripe
would start on an odd pixel location.)
Horizontal filter components
In color space matrix mode this value has to remain zero.
0: 64 phases
1: 32 phases
2: 16 phases
3: 8 phases
4: 4 phases
5: 2 phases
6: fixed phase
7: linear phase interpolation (only valid for 4 component mode)
0: cropping enabled (default)
1: cropping disabled, used for striped scaling tasks
0: normal sequence (default)
1: skip first chroma sample
0: three components, 6 tap FIR each
1: four components, 3 tap FIR each
