Product data sheet
Destination pixels always reside in memory. Source pixels may either come from
memory (if they are in the same color format as the destination) or from the host data
port. In addition to accepting pixels in the destination format, the host data port also
accepts 4 or 8-bit alpha values. In this case, the color values for each source pixel
come from the MonoHostBColor register (address 1424h).
The source pixels may contain either ‘normal’ or ‘pre-multiplied’ color values. If the
source pixel is pre-multiplied, the alpha value in the source pixel is not applied to the
source pixel. ‘Normal’ color values will have the source alpha applied.
In addition to blending source and destination data using the source’s alpha, the
drawing engine also has a global “surface alpha.” The surface alpha is applies to all
pixels in a alpha BLT. Surface alpha is stored in the MonoHostFColor register
(address 1420h).
Two aYUV:8888 formats are supported. One of the formats (PFormat=1) assumes full
range YUV data i.e., 0xff..0x00. The other format, (PFormat=2) assumes the normal
D1 limited range of values: Y:235:16, U/V:240:16.
The following algorithm describes the alpha blending data flow. We assume that all
values have been normalized to a range of 1..0. In reality, this will be represented by
actual values of 0xFF..0x00.
