Operator LineEndToSignal

Operator Library: Signal

The operator generates a signal pulse when the end of a input image line is detected. The operator input is an image stream. The operator waits for the end of lines at the input image stream. When the line end is detected, a signal pulse of one clock cycle is output. Note that the end of a line might not occur directly after the last line pixel. See the following figure for explanation:

The end of a frame always occurs at the same time as the end of the last frame line. Note that empty lines can exist in VisualApplets. The operator will generate a signal pulse for empty lines, too.

This operator is excluded from the VisualApplets functional simulation.
