Bit 10-1

LineSize[10:1]

This register defines the maximum number of bytes to be captured

per line. The value in this register must be written prior to initiating the

video capture. Bit 0 is a constant zero in order to ensure that line size

is an even number, i.e., on the word boundary.

If the number of actual data is more than this value, then the actual

data will be truncated. It should be noted that at the end of every line,

one or two byte of zeros will be added in order to indicate the end of

line, and at the same time the additional zeros will guarantee that the

line length is on the word boundary. Whenever the actual data does

not match the LineSize, the “Video Error” bit in “Video Capture Config”

Note: The jump or skip parameter in DMA setting must be at least 1 halfword bigger than the

“LineSizeCfg” in order to take into account the additional zeros at the end of line.

Example of line too short

VidLineCfg = 10 bytes

Number of actual data from video decoder = 9 bytes

Number of actual data stored into memory = 9 bytes

Number of zeros inserted into memory = 1 byte

Final line size = 10 bytes

Example of line too long

VidLineCfg = 10 bytes

Number of actual data from video decoder = 11 bytes

Number of actual data stored into memory = 10 bytes

Number of zeros inserted into memory = 2 byte

Final line size = 12 bytes

Example of line is just right

VidLineCfg = 10 bytes

Number of actual data from video decoder = 10 bytes

Number of actual data stored into memory = 10 bytes

Number of zeros inserted into memory = 2 byte

Final line size = 12 bytes
