Am I understanding it correctly that it takes analog signals as input, digitizes them, processes them, and then outputs them as analog again? Strange indeed. I've always thought of DSPs as specialized chips that process an already digital signal that may come from an ADC but also from memory for example.
@grishka Yes, that's how the chip works. It has 4 analog inputs and 8 analog outputs and the analog/digital conversion is done on the chip. There are no digital inputs or outputs (unless you use an analog I/O as digital).
