1 OVERVIEW
Mixer overlaps or blends the input data such as graphic, video, background and sends the result data to the
TVOUT module that generates all the video control signals.
Graphic data is transferred to the mixer from External DRAM memory through AXI interface. However, the video
data is transferred to the mixer through direct connection with pre-defined protocol. The data generated from
mixer is directly transferred to TVENC/HDMI module for the real time transfer.
