VOICE PROCESSING LSI

摘要

PROBLEM TO BE SOLVED: To reduce the scale of an error check circuit in the voice formats of AC-3 Standard and MEPG Standard. SOLUTION: An error check circuit 2 is used to check whether an error is present or not in the voice format of AC-3 Standard before decode processing and the voice fomtat of MEPG Standard after decode processing. In addition to s first memory circuit 4 for decode processing, a second memory circuit 5 is installed for outputting the voice format in compliance with the interface standard of IEC 958 to commonly use the signal required for write operation of two memory circuits.
