Signal

Width

Direction

Description

aes_clk

[0:0]

Input

Audio input clock.
aes_de

[0:0]

Input

Audio data enable.
aes_ws

[0:0]

Input

Audio word select.
aes_data

[0:0]

Input

Audio data input in internal AES format.

This table lists the Avalon-ST audio signals when you instantiate the SDI Audio Clocked Input IP core in Platform Designer (Standard).

Description

aud_clk

[0:0]

Input

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

[0:0]

Input

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

[0:0]

Output

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

aud_sop

[0:0]

Output

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

[0:0]

Output

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

[23:0]

Output

Avalon-ST data bus. The core asserts this signal to transfer data.

This table lists the direct control interface signals. The direct control interface is internal to the audio extract component.

Description

channel0

[7:0]

Input

Indicates the channel number of audio channel 1.
channel1

[7:0]

Input

Indicates the channel number of audio channel 2.
fifo_status

[7:0]

Input

Drive bit 7 high to reset the clocked audio input FIFO buffer.
fifo_reset [0:0] Output Assert this signal when the clocked audio input FIFO buffer overflows.
