3.9.4 Decoded Image Related Registers
3.9.4.1 Y0 Frame Buffer Start Address Register (H264Y0SA)
This register configures the Y0 Frame Buffer region which contains decoded Images stored by the H.264 Decoder.
Address: FFE0 1C20h
Bit
31 : 0
R/W
R/W
Description
Frame_Buffer_Y0 Start Address
Default Value
0h
Decoder uses 3 Frame Buffers for Y(Luminance). Scaler reads the Start Address of Y Frame Buffer from Decoder
during bank switching through Frame Sync signal synchronization.
