(2) Calculation of
output position
(nth row and
below)
Description
The following formulae are used to compute output positions (nth row and
below) (DDR2-SDRAM output address).
Output address formulae for nth row and below
•
Subsequently, data for 16 dots (= 16 bytes) is processed in succession
•
Subsequently, data for 8 dots (= 8 bytes) is processed in succession
V pointer address is calculated using a formula similar to that for the U pointer
address.
Y output target address
Calculation formula: Output frame Y point value (base point) + [(mbrow ×
16 + n - 1) × (width + Y padding)] + [mbcol × 16]
Output frame Y pointer value (base point): MCOYPR setting address
mbrow: Calculated from MCCF setting
mbcol: Calculated from MCCF setting
width: Calculated from MCWR setting
Y padding: Calculated from MCYPR setting
U/V output target address
Calculation formula: Output frame U point value (base point) + [(mbrow ×
8 + n - 1) × (width/2 + U padding)] + [mbcol × 8]
Output frame U pointer value (base point): MCOUPR setting address
mbrow: Calculated from MCCF setting
mbcol: Calculated from MCCF setting
width: Calculated from MCWR setting
U padding: Calculated from MCUVPR setting
