S3C6400X RISC MICROPROCESSOR
one of YCbCr420, YCbCr422, and RGB 16/18/24 bit format.
All source and destination image data must be stored in memory system aligned with word boundary. It means
that neither byte nor half-word size DMA operations are supported. Therefore, the width of source and destination
image must be selected to satisfy the word boundary condition.
- FIFO Mode Operation
In FIFO Mode, (LCDPathEn =1), two types of color space conversion such as RGB2YCbCr and YCbCr2RGB
are available like a DMA mode operation. Destination image is transferred to the FIFO in display controller (or
some other IP with FIFO interface) without additional memory bandwidth such as FIMC-to-Memory and Memory-
to-Display Controller. Output data format is determined by only Output format register: OutFormat_xx=RGB format
(24bit RGB) or OutFormat_xx=YCbCr format (YCbCr444). The source image format and the destination image
format restriction are described in the following table.
In FIFO mode (LCDPathEnable =1), either progressive or interlace scan mode can be selectable according to
"interlace" control register. Register Files Lists. The "interlace" control bit is available only if LCDPathEn=1,
otherwise its value is unaffected to DMA mode operation which support only progressive.
Even if an interlaced scan mode is enable (LCDPathEn = 1 and Interlace = 1), per frame management, which
consists of even field and odd filed, is automic. This means that user interruption is unnecessary to inter field
switching in the same frame. Therefore, the frame management scheme is identical for both progressive and
interlace scan mode. Interlace is not supported when camera processor is selected input
