Chapter 12: Color Plane Sequencer MegaCore Function 12–5
Parameter Settings
January 2013 Altera Corporation Video and Image Processing Suite
User Guide
The latency is measured with the assumption that the MegaCore function is not being
stalled by other functions on the data path (the output ready signal is high).
1 The latency associated with the initial buffering phase, when a MegaCore function
first receives video data, is not included.
Parameter Settings
Table 12–3 lists the Color Plane Sequencer MegaCore function parameters.

Note to Table 12–2:
(1) O refers to a small number of clock cycles, and is not of zero value.
