The invention relates to a multi-parameter configurable Viterbi decoder with low resource consumption. The multi-parameter configurable Viterbi decoder comprises an input configuration unit used for standardizing decoding inputs, a standard code calculation unit used for calculating standard recurrent codes, a branch metric calculation unit used for calculating branch metric values, a grid computation unit used for reconstructing a grid chart and calculating survival paths, a status metric storage and comparison unit, a survival path storage unit, and a backtracking unit used for reconstructing a decoding sequence according to the survival paths and the grid chart. The invention provides a recursive reuse method for the standard code calculation unit. The method comprises the following steps: enumerating four groups of status codes as standard code elements, calculating the standard recurrent codes of the standard code elements, sequentially overturning the highest five digits and the lowest digit of each standard code element, carrying out iterative computation of the standard recurrent codes of the standard code elements and the overturned bits, and obtaining the standard recurrent codes of all the status codes after the iterative computation has been carried out for six times. The method has the advantages that the standard code elements are reused for calculation, so that resource consumption is reduced.
