(3) Calculation of
input position
(first row)
Description
•
Depending on the motion vector value, 8-dot data (8 bytes) or 9-dot data (9
bytes) is processed in succession.
Future frame U pointer address is calculated using a formula similar to that for
the past frame.
V pointer address is calculated using a formula similar to that for the U pointer
address.
* Calculation result for Recon_down/2>>1 is shown below:
Calculation result for Recon_right/2>>1 is the same.
Recon_
down
Recon_
down/2>>1
U/V input comparison address
Calculation formula: Past frame U point value (base point) + [(mbrow × 8 +
(Recon_down/2>>1)) × (width/2 + U padding)] + [mbcol × 8 +
(Recon_right/2>>1)]
Past frame U pointer value (base point): MCPUPR setting address
mbrow: Calculated from MCCF setting
mbcol: Calculated from MCCF setting
Recon_down: Calculated from MCCF setting
Recon_right: Calculated from MCCF setting
width: Calculated from MCWR setting
U padding: Calculated from MCUVPR setting
