(3) Calculation of
input position
(first row)
Description
The following formulae are used to compute input position (first row) (DDR2-
SDRAM input address).
First row input address formulae
•
Depending on the motion vector value, 16-dot data (16 bytes) or 17-dot data
(17 bytes) is processed in succession.
Future frame Y pointer address is calculated using a formula similar to that for
the past frame.
* Calculation result for Recon_down>>1 is shown below:
Calculation result for Recon_right>>1 is the same.
Recon_
down
Recon_
down>>1
Y input comparison address
Calculation formula: Past frame Y point value (base point) + [(mbrow × 16
+ (Recon_down>>1)) × (width + Y padding)] + [mbcol × 16 +
(Recon_right>>1)]
Past frame Y pointer value (base point): MCPYPR 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
Y padding: Calculated from MCYPR setting
