1. Introduction
1.1 Features
The Audio Input block can have up to four audio input ports. Each audio input port
supports single or dual-channel sources. Hence the Audio In block can support up to
8 channels of audio input (4 stereo channels).
The Audio In module provides a DMA-driven serial interface to an off-chip stereo A/D
converter, I
needed to connect to high quality, low cost oversampling A/D converters. The Audio
In module and external A/D converter (or I
generating a programmable sample clock by dividing a precise oversampling clock,
which is an input to this block. It is assumed that a programmable clock generator for
a precise oversampling A/D system clock is present elsewhere in the chip.
Remark: AC-97 codecs are not supported.

Four channels of audio input per port
16 or 32-bit samples per channel
Programmable 1 Hz to 100 kHz sampling rate
(Note: This is a practical range. The actual sample rate is application dependent.)
Internal or external sampling clock source
Audio In autonomously writes sampled audio data to memory using buffering
(DMA)
16-bit and 32-bit mono and stereo PC standard memory data formats
Raw mode where the bits from all the active inputs are sampled by bit clock along
with the frame sync signal (WS) and packed into one 8 bit byte in memory for
software to tear apart.
Little or big-endian memory formats.
