THD with prescalar enabled is 6dB less than the specification.
SNR with prescalar enabled is 6dB less than the specification.
SINAD with prescalar enabled is 6dB less than the specification.
For the Quartus II software version 15.0 and later, Altera Modular ADC and Altera Modular Dual ADC IP cores handle the 64 samples averaging.
For the Quartus II software versions prior to 14.1, you need to implement your own averaging calculation.
