Loeffler Dct, Chi‐Chia Sun, Shanq-Jang Ruan · 2006
In this paper, alow-power andhigh-quality pre- Thispaperisorganized asfollows. Section IIbriefly intro- serving DCT architecture ispresented. Itisobtained byopti-ducesthealgorithms oftheCordic basedDCT.InSection III, mizing theLoeffler DCT basedontheCordic algorithm. The wewill present thesolution approach oftheproposed Cordic experimental results showthattheproposed DCT architecture occupies 19%oftheareaandconsumes about 16%ofthepowerbased Loeffer DCT algorithm anditsflowgraphdiagram. The compared totheoriginal Loeffler DCT.Additionally thegood experimental results areshowninSection IVwhileSection V transformation quality isretained. Inthis regard, theproposedconcludes this paper. Cordic basedLoeffler DCT isverysuitable forlow-power and high-quality CODECs,especially forbattery-based systems.
