Thee transform coding is a major block in any compression technique.Transform coding helps in decorrelating the input data and for energy compaction which are required to implement compression.DCT is standard transform used in JPEG image compression standard and DWT is used in JPEG2000image compression standard.The DHT is a transform which provides flexibility in terms of hardware as well as reduces complexity in evaluation inverse transform because it is inverse is same as forward transform hence recently DHT is also using in image compression techniques so low hardware required, high speed architecture is required for DCT, DWT and DHT.In this paper DA based optimized adder tree architecture was presented
