Dedicated Digital Signal Processor (DSP)
A dedicated Digital Signal Processor (DSP) takes charge of all audio processing features and the
low frequency signal processing features of the demodulator. The internal 24-bit architecture will
ensure a high quality signal treatment and an excellent dynamic.
4.1
Back-end Processing
The “back-end” processing corresponds to the low frequency signal processing (32 kHz or higher
frequencies) of the demodulator and other inputs (I²S, ADC).
Figure 11 shows a flowchart of the back-end processing tasks. However, the figure shows that the
processing is only a SINGLE SOURCE PROCESSING flow (no processing is possible with
“Demod + SCART” and I²S inputs simultaneously) and that the selection of a headphone output
restricts the loudspeakers configuration to 2+1 instead of 5+1.
