OMAP-L13X or C674X DSP
Channels desired for mixing are communicated by the DSP to the FPGA,
which acts as the traffic controller in the system. Once the signals are
digitized or normalized, they are sent to the DSP which performs the
audio mixing/processing requested by the user. The mixed audio signals
are then sent out to speakers, headphones or other digital devices.

Pre-ADC Signal Chain
• The following covers
– Mic Pre-amps, Signal Chain Op-amps
ADC Front End
Amp/Buffer
A/D
Converter
• Real world signals in professional audio can go from tiny mV signals
(microphones) through to broadcast level
• Pre-ADC front end circuitry must be able to handle input voltages and
scale them to the ADC input voltage.
– Low noise gain stages and high voltage (±15V) op-amps.
