A method for decoding coded data is executed to use a decoder composed of plural decoding units, those units being parallel processors. The coded data is divided into a first and a second coded areas. A first decoding unit starts to decode the coded data from the head of the first coded area, that is, from the head of the overall coded data. A second processor starts the decoding process from the head of the second coded area, that is, from any location of code sequence from the head. If conflict takes place in the decoded data, the decoding device operates to repeat a trial-and-error operation for re-starting the decoding process from a new location close to the head of the second coded area. When the decoding process of the first decoding unit reaches the second coded area, if a right answer is found in the decoded result given by the second decoding process, it is picked up as the proper result.
