RAME GENERATION
The output frame contains three main regions:
Blanking region
Border region
Active video region.
The blanking region contains all front and back porch as
well as the synchronization intervals. The border region is
visible on the panel and is used for positioning the active
video region inside this visible area. To ensure a great
flexibility in the ‘sync to input’ mode there are 3 different
horizontal length counters (h_len_blank, h_len_border,
h_len_active) with independent length control
(see Fig.17).
A maximum value must be programmed in h_max_len
which is the upper limit for line lengthening during
activated control mechanism. In free running mode all
3 counters should be programmed with the same
minimum values.
If no border is needed, because the active video region
covers the visible area of the panel, the active video length
counters should point to the same positions as the border
length counters. Then the active video length counters
have a higher priority.
The border colour inserted by the output interface is the
same as the blank colour in the memory interface;
blank_colour_red, blank_colour_green,
blank_colour_blue.
