Abstract
Abstract A voice encoding/decoding apparatus has a data buffer holding voice data and encoded data, a decoding process unit which receives the voice data of one subframe from the data buffer to decodes the same and outputs obtained encoded data of one subframe to the data buffer, a decoding process unit which receives the encoded data of one subframe from the data buffer to decodes the same and outputs obtained voice data of one subframe to the data buffer, a frame synchronization detecting unit, a first clock generating unit providing timing of inputting/outputting the voice data to/from the data buffer, a second clock generating unit providing timing of inputting/outputting the encoded data to/from the data buffer, a word transfer information providing unit providing the number of words of the voice data and the number of words of the encoded data to be inputted/outputted to/from the data buffer, and information about positions of the voice data and the encoded data in the data buffer, and a control unit minimizing a time required from an inputting to an outputting of the data upon encoding and decoding the data of each subframe on the basis of the information provided by the word transfer information providing unit.
