Description

aud_clk

[0:0]

Input

Clocked audio clock. All the audio input signals are synchronous to this clock.
aud_ready

[0:0]

Output

Avalon-ST ready signal. Assert this signal when the device is able to receive data.
aud_valid

[0:0]

Input

Avalon-ST valid signal. The core asserts this signal when it receives data.

aud_sop

[0:0]

Input

Avalon-ST start of packet signal. The core asserts this signal when it is starting a new frame.
aud_eop

[0:0]

Input

Avalon-ST end of packet signal. The core asserts this signal when it is ending a frame.
aud_data

[23:0]

Input

Avalon-ST data bus. This bus transfers data.
