Abstract
A single-chip decoder LSI is developed for ISO/IEC MPEG (the Internati onal Organisation for Standardisation/the International Electrotechnic al Commission, Moving Pictures Expert Group) audio. The applicable lay ers are Layer I and LT of MPEG-1 and MPEG-2/Lower-Sampling-Frequency M ode. A fast calculation algorithm, which is also effective for on-chip memory reduction, is incorporated in audio signal synthesis. The reli ability in bitstream synchronization is improved by including bitstrea m inconsistency detection. Bitstream error concealment by repeating pr evious audio data is supported. The decoding delay is adjustable when an optional external memory is connected to the LSI.
