Display Interface Unit (DIU)
10.4.3
The DIU has been designed for maximum flexibility in the format of its input data. Each pixel can contain
as many as four basic components: alpha, red, green, and blue. The contents of several registers in an area
descriptor (see
The first step is to define the size of each pixel (PIXEL_S+1) and the number of bits for each component
of a pixel (COMP_0 to COMP_3) in the data stream. The next step is to assign the components of the pixel
(alpha, R, G, and B) to the components of the data stream (COMP_0 to COMP_3). The RED_C,
GREEN_C, BLUE_C, and ALPHA_C fields in the pixel format (word 0) of the AD are used to control the
assignments, selecting which component is red, which is green, and so on. The three color components
(red, green, and blue) must be mapped to one of the components of the data stream; alpha can be assigned
to a fourth component of the data stream or the pixel can use the global alpha value specified for the current
area descriptor (G_ALPHA in word 2).
The pixel format (word 0) of the AD also contains the BYTE_F bit, which can have a significant impact
on the way the DIU interprets the pixel data. If the BYTE_F bit in the AD is set (that is, flipping is disabled)
then the pixel is constructed as shown in
If the BYTE_F bit in the AD is cleared (that is, bytes in the pixel are flipped) then the pixel is constructed
as shown in
