Image port output formatter
(subaddresses 84H to 87H)
The output interface consists of a FIFO for video and for
sliced text data, an arbitration circuit, which controls the
mixed transfer of video and sliced text data over the I port
and a decoding and multiplexing unit, which generates the
8 or 16-bit wide output data stream and the accompanied
reference and supporting information.
The clock for the output interface can be derived from an
internal clock, decoder, expansion port, or an externally
providedclockwhichisappropriatefore.g.VGAandframe
buffer.Theclockcanbeupto33 MHz.Thescalerprovides
the following video related timing reference events
(signals), which are available on pins as defined by
subaddresses 84H and 85H:
Output field ID
Start and end of vertical active video range
Start and end of active video line
Data qualifier or gated clock
Actually activated programming page (if CONLH is
used)
Threshold controlled FIFO filling flags (empty, full, filled)
Sliced data marker.
The discontinuous data stream at the scaler output is
accompanied by a data valid flag (or data qualifier), or is
transported via a gated clock. Clock cycles with invalid
dataontheI portdatabus(includingtheHPDpinsin16-bit
output mode) are marked with code 00H.
The output interface also arbitrates the transfer between
scaled video data and sliced text data over the I port
output.
The bits VITX1 and VITX0 (subaddress 86H) are used to
control the arbitration.
As a further operation the serialization of the internal 32-bit
Dwords to 8-bit or optional 16-bit output, as well as the
insertion of the extended ITU 656 codes (SAV/EAV for
video data, ANC or SAV/EAV codes for sliced text data)
are done here.
For handshake with the VGA controller, or other memory
or bus interface circuitry, programmable FIFO flags are
provided; see Section 8.5.2.
