Each AXI input
interface has its own reset signal.
The reset signals, s_axi_cpu_aresetn
, s_axis_video_aresetn
, and s_axis_audio_aresetn
are for S_AXI_CPU_IN
, VIDEO_OUT
(AXI4-Stream
Video Interface), and AUDIO_OUT
respectively.
These three reset signals are
active-Low. Because the reset signal is used across multiple sub-blocks in the
subsystem, keep the system in the reset state until all the clocks are stabilized.
You can use the locked
signal from the clock
generation block as a reset signal.
Note: There is
no dedicated hardware reset for NATIVE_VID_OUT interface when Native Video or Native
Video (Vectored DE) interface is selected. However, the HDMI 1.4/2.0 RX Subsystem outputs a
video_rst
signal, which you can use to reset its supporting Native Video or Native Video (Vectored
DE) Source processing modules.
