4.5. Full-Raster I/O Signals

Table 10.  Full-Raster Transmitter Interface Signals
Signal Name Width Direction Default Value Optional or Required Description
TUSER[0]

As per Intel FPGA streaming video protocol specification.

For TDATA bus, extend the number of color planes by 1, to consider the extra full-raster stream.

Output Low Required Full-raster start of frame. Indicates full-raster true start of frame, i.e., where video geometry counters are in coordinates (0,0), irrespective of where the actual leading edge of VSYNC occurs.
TDATA Output - Required Data payload
TVALID Output - Required Indicates that the transmitter interface is driving a valid transfer. A transfer takes place when both TVALID and TREADY are asserted.
TREADY Input - Optional

Indicates that a receiver interface can accept a transfer.

When TREADY is not present in the transmitter interface, it indicates that this interface does not support backpressure.

TLAST Output Low Required Full-raster end of line. Indicates the last pixel of the full-raster line.
Table 11.  Full-Raster Receiver Interface Signals
Signal Name Width Direction Default Value Optional or Required Description
TUSER[0]

As per Intel FPGA streaming video protocol specification.

For TDATA bus, extend the number of color planes by 1, to consider the extra full-raster stream

Input - Required Full-raster start of frame. Indicates full-raster true start of frame, where video geometry counters are in coordinates (0,0), irrespective of where the actual leading edge of VSYNC occurs.
TDATA Input - Required Data payload
TVALID Input - Required Indicates that the transmitter interface is driving a valid transfer. A transfer takes place when both TVALID and TREADY are asserted.
TREADY Output High Optional

Indicates that a receiver interface can accept a transfer.

When TREADY is not present in the receiver interface, indicates that this interface can always accept a transfer.

TLAST Input - Required Full raster end of line. Indicates the last pixel of the full-raster line.
