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