Notes to
(1) It is assumed that the MegaCore function is not being stalled by other functions on the data path (the output ready signal is high).
(2) Add 1 cycle if Allow color planes in sequence input is turned on.
(3) Minimum latency case when video input and output rates are synchronized.
Table
5–28:
1
The latency associated with the initial buffering phase, when a MegaCore function
first receives video data, is not included. For example, the Deinterlacer MegaCore
function in motion-adaptive mode initially buffers four fields of video in external
memory without outputting data. After the initial buffering phase, the latency from
field input to frame output (assuming the output frame rate is the same as the input
field rate) is one field + O (lines).
