In　the　recent　audio　codec　standard　LC3　plus,　a　good　balance　between　low　latency　and　algorithm　complexity　has　been　achieved　This　standard　introduces　a　new　quantization　algorithm.　To　reduce　system　resource　consumption　and　area　usage,　as　well　as　to　increase　operation　speed,　this　paper　implements　an　efficient　hardware　architecture　for　the　dead-zone　plus　uniform　threshold　scalar　quantization　(DUTSQ)　algorithm　under　low-latency　modified　discrete　cosine　transform　(LD-AMUR,　based　on　low-latency　time-domain　diming　cancellation　(LD-TDAC)　technology.　The　proposed　quantization　hardware　architecture,　based　on　state　machines　and　folded-multiplexed　data　paths　(SFDP)　technology,　significantly　reduces　system　resource　consumption.　Verified　using　Altera　MAX　10　technology,　the　hardware　architecture　operates　at　a　frequency　of　75　MHz,　with　logical　resources　occupying　16%　of　the　total　resources.
