摘要

A single-chip decoder LSI is developed for audio bit-stream specified by ISO/IEC MPEG (the International Organisation for Standardisation/the International Electrotechnical Commission Moving Pictures Expert Group). The applicable layers are Layer I and II of MPEG-1 and MPEG-2/lower-sampling-frequency mode. To reduce on-chip memory for audio signal synthesis the LSI employs a fast calculation algorithm that was developed when the decoder was realized by signal processors. The reliability in bitstream synchronization is improved by checking bitstream inconsistency. Bitstream error concealment by repeating previous audio data is supported. The decoding delay is adjustable when connected with an optional external memory.
