Abstract
Presented in this paper are energy-optinium reconfigurationstrutegies for channel codecs. These strategies are derived by solving an optimizationproblem, which has energy consumptionasthe objective function and a constraint on the bit error-rate (BER). Energy consumptionmodels for a reconfigurableReed-Solomon(RS) codec are derived via gate-level simulationof the finite field arithmetic modules. Theseenergy models along with the BER expressions are then employed to derive the energy-optimum reconfiguration strategies. The energy savings are computed by comparing the energy consumptionof the reconfigurablecodec with that of the static codec. The energy savings range from 0%-83% for channel signal-to-noiseratio (SNR)variations from 7dB-lOdB. On an average 55%energy savings are achieved.
