POWER EFFICIENT BATCH-FRAME AUDIO DECODING APPARATUS, SYSTEM, AND METHOD

摘要

PROBLEM TO BE SOLVED: To reduce battery consumption in audio decoding in a mobile device.SOLUTION: Generated audio samples are transferred into at least one memory bank in a power saver block within a mobile device. The power to parts of a decoding system not involved in storing the generated audio samples are switched off after batch decoding of a bitstream associated with multiple audio frames is completed. The bitstream includes fewer bits than those included in one audio file. The memory bank allows power shutoff. Fetching of the decoded can be synchronized with a paging channel of a modem in the mobile device. The transferred audio samples are a lossless compression and may occur after re-encoding.
