Color space conversion coefficients are defined with one sign bit, 2 integer bits and 7 fractional
bits. The range of the CSC coefficients is defined below with a step of 1/128.
(Note)
Additionally a set scaling factor {Yoff, Cboff, Croff} can be applied.
The High End Overlay (HEO) data path includes a hardware scaler that allows image resize in
both horizontal and vertical direction.
The XMEM_SIZE field of the LCDC_HEOCFG4 register indicates the horizontal size minus one
of the image in the system memory. The XSIZE field of the LCDC_HEOCFG3 register contains
the horizontal size minus one of the window. The SCALEN field of the LCDC_HEOCFG13 regis-
ter is set to one. The scaling factor is programmed in the XFACTOR field of the
LCDC_HEOCFG13 register.
The YMEM_SIZE field of the LCDC_HEOCFG4 register indicates the vertical size minus one of
the image in the system memory. The YSIZE field of the LCDC_HEOCFG3 register contains the
vertical size minus one of the window. The SCALEN field of the LCDC_HEOCFG13 register is
set to one. The scaling factor is programmed in the YFACTOR field of the LCDC_HEOCFG13
register.
The LCD module integrates a hardware cursor database. This layer features only a minimal set
of color among 1, 2, 4 and 8 bpp palletized and 16 bpp to 32 bpp true color. The cursor size is
limited to 128 x 128 pixels.
The LCD module provides hardware support for multiple “overlay plane” that can be used to dis-
play windows on top of the image without destroying the image located below. The overlay
image can use any color depth. Using the overlay alleviates the need to re-render the occluded
portion of the image. When pixels are combined together through the alpha blending unit, a new
color is created. This new pixel is called an iterated pixel and is passed to the next blending
stage. Then, this pixel may be combined again with another pixel. The VIDPRI field located in
the LCDC_HEOCFG12 register configures the video priority algorithm used to display the lay-
CSC values for all matrix coefficients.
