摘要： A method for conditionally stopping execution of a turbo decoder is proposed. The decoder has elementary decoders. Each elementary decoder performs a sequence of decoding operations and is arranged to receive an input from at least one other elementary decoder. The method determines for each specific decoding operation if the sequence of elementary decoding operations of the specific elementary decoder has substantially converged or substantially diverged. The method terminates the execution of decoding operations if a number of sequences has substantially converged or substantially diverged.

摘要： The invention relates to the domain of turbo decoders. Such a decoder comprises a first decoder (14) and a second decoder (16), each decoder being able to calculate extrinsic output data from extrinsic input data coming from the other decoder. The decoding circuit according to the invention comprises a single memory (31) for storing the extrinsic data. When a decoder calculates an extrinsic output data from an extrinsic input data coming from the other decoder and stored in the single memory at a certain address, this extrinsic output data is then written at this same address.
