6. A resource access control method for use in an audio signal decoder having first and second decoding units which decode first and second encoded audio signals respectively, and a memory in which data under decoding as well as data which has been decoded by the first and second decoding units are stored, said resource access control method comprising:
-
receiving a completion notification from one of the first and second decoding units, the completion notification indicating that decoding of a predetermined unitary amount of the encoded audio signal is completed; and selecting one of the first and second decoding units as a device having access to the memory, in response to the completion notification.
