[non-BE] Resolve: "ivas_param_mc_dec_reconfig sums Pow2 mantissas with mismatched exponents"

Mohammadreza Naghibzadehrequested to merge
basop-2627-ivas_param_mc_dec_reconfig-sums-pow2-mantissas-with-mismatched-exponents into main

Reason why this change is needed

  • In the ivas_mc_param_dec_fx.c, ILD loop, each p_ild_new_fx is computed with BASOP_util_Pow2, this function returns a mantissa and an exponent, but p_ild_new_e is overwritten in each loop iteration. The code accumulates the raw mantissas while only using the exponent from the last iteration during the dB conversion, which can lead to an incorrect result when the exponents differ.

Description of the change

  • Accumulate 10^(ILD/10) using a dynamic exponent.

Affected operating points

  • non-BE

Closes #2627 (closed)
