Signal
Clocked audio clock. All the audio input signals are synchronous
to this clock.
Input
[0:0]
aud_clk
Avalon-ST ready signal. Assert this signal when the device is able
to receive data.
Output
[0:0]
aud_ready
Avalon-ST valid signal. The core asserts this signal when it receives
data.
Input
[0:0]
aud_valid
Avalon-ST start of packet signal. The core asserts this signal when
it is starting a new frame.
Input
[0:0]
aud_sop
Avalon-ST end of packet signal. The core asserts this signal when
it is ending a frame.
Input
