摘要:
A PAM equalization optimization system includes a BIOS coupled to a PAM engine and an equalization engine. The BIOS determines an effective equalization tap number of equalization taps that each provide an equalization result above a predetermined amount. The BIOS then determines whether the effective equalization tap number is greater than a predetermined fraction of an available equalization tap number of equalization taps that are available for equalizing a signal. When the effective equalization tap number is greater than the predetermined fraction of the available equalization tap number, the BIOS causes the equalization engine to perform per-symbol equalization on signals modulated using the PAM engine. When the effective equalization tap number is not greater than the predetermined fraction of the available equalization tap number, the BIOS causes the equalization engine to perform per-bit equalization on signals modulated using the PAM engine.
