Splitting/Packing Options
Each EPPI word is zero filled or sign extended to 16 bits.
EPPI_CTL.SPLTEO =1.
EPPI_CTL.SUBSPLTODD =1 if necessary to separate chroma compo-
nents.
No splitting possible.
EPPI_CTL.PACKEN =1. Two EPPI words are zero filled or sign exten-
ded to 16 bits and packed to 32-bit DMA data.
EPPI_CTL.PACKEN =0. Each EPPI word can be zero filled or sign ex-
tended to 16 bits and sent as a 16-bit data on the 32-bit DMA bus. This
transfer consumes double the bandwidth of the 10-bit case with
EPPI_CTL.PACKEN =1;
Each EPPI word is zero filled or sign extended to 16 bits.
EPPI_CTL.SPLTEO =1
SEPPI_CTL.SUBSPLTODD = 0 since there are only two components.
No splitting possible.
EPPI_CTL.PACKEN =1. Two EPPI words are zero filled or sign exten-
ded to 16 bits and packed to 32-bit DMA data.
EPPI_CTL.PACKEN =0. Each EPPI word can be zero filled or sign ex-
tended to 16 bits and sent as a 16-bit data on the 32-bit DMA bus. This
transfer consumes double the bandwidth of the 12-bit case with
EPPI_CTL.PACKEN =1;
Each EPPI word is zero filled or sign extended to 16 bits.
EPPI_CTL.SPLTEO =1
EPPI_CTL.SUBSPLTODD =0 since there are only two components.
