TM1300 Data Book
As with the video units, the audio-in and audio-out units
buffer incoming and outgoing audio data in SDRAM. The
audio-in unit buffers samples in either 8- or 16-bit format,
mono or stereo. The audio-out unit transfers 16- or 32-bit
sample data for mono, stereo or up to 8 audio channels
from memory to the external DACs. Any manipulation or
mixing of sound data is performed by the DSPCPU since
this processing will require only a small fraction of its pro-
cessing capacity.
2.5.8
The Sony/Philips Digital Interface Out (SPDO) unit al-
lows output of a 1-bit high-speed serial data stream. The
primary application is output of digital audio data in Sony/
Philips Digital Interface (S/PDIF) format to an external
electrically isolated transformer. The SPDO unit can also
be used as a general purpose high-speed data stream
output device such as a UART.
The SPDO unit supports 2-channel PCM audio, one or
more Dolby Digital six-channel data streams, or one or
more MPEG-1 or MPEG-2 audio streams (embedded
per Project 1937). It supports arbitrary programmable
sample rates independent of and asynchronous to the
AO unit sample rate.
2.5.9
The on-chip synchronous serial interface (SSI) is spe-
cially designed to interface to high integration analog mo-
dem frontends or ISDN frontend devices. In the analog
modem case, all of the modem signal processing is per-
formed in the TM1300 DSPCPU.
