GD32H757xx Datasheet



Supports stereo stream from 8 to 192 kHz.



Supports automatic symbol rate detection.



Genrate symbol clock.



Check the parity bit of the received data.



Support multiple data processing methods, which can process audio data and user

channel information separately or together.



Supports using DMA communication to receive audio data and user channel

information respectively.

The receiver of Sony/Philips Digital Interface (RSPDIF) module provides the function of

receiving and decoding RSPDIF audio data streams.

Serial Audio Interface (SAI)



Two independent audio sub-blocks.



Each audio sub-block can be configured as any of the master/slave and

transmitter/receiver combination with 8-word FIFO.



Local clock divider logic to satisfy the various audio sampling rates.



Flexible audio protocol configuration such as I2S, PCM/DSP, AC’97, LSB or MSB-

justified and TDM.



PDM interface, supporting up to 3 microphone pairs.



Mono/Stereo audio capability with mute option.



Frame Synchronization configuration (active level, active length and offset).



Each audio frame contains up to 16 configurable slots.



Slot length is flexible, and can be configured as active or inactive.



Each slot can hold a data of size 8-, 10-, 16-, 20-, 24-, and 32-bits with configurable first

bit offset, and configurable LSB or MSB data transfer.



Two independent DMA interface for each audio sub-block. Support slave mode with a

frequency up to 4MHz.

The Serial Audio Interface (SAI) is designed to target a wide range of commonly used audio

protocols, both in mono and stereo modes, such as I2S, PCM/DSP, AC’97, LSB or MSB-

justified and TDM. SPDIF output is offered when the audio block is configured as a transmitter.

The SAI can be configured to any of the master/slave and transmitter/receiver combination,

full/half-duplex operating mode depends on synchronous/asynchronous configuration of the

audio sub-blocks.

3.32.

Image processing accelerator (IPA)



Copy one source image to the destination image.



Convert one source image to the destination image with specific pixel format.



Convert and blend two source images to the destination image with specific pixel format.



Fill up the destination image with a specific color.
