Abstract: In Low power VLSI design, the significance of the lifting scheme is enhanced nowadays due to high throughput. The concept of lifting scheme is mainly based on spatial domain technique and split, predict, and update the three different steps associated with the system. Data compression, Signal transmitting algorithm, information translation, weather forecasting, processing the audio signal, and the primary work using the Discrete Wavelet Transform (DWT). In very few applications, need to concentrate on scalability and degradations before developing the core concept in it. In this project, an efficient Multiplier less predict and update the structure for lift up based DWT. This proposed method is to reduce the complexity in Multiplier based lifting architecture. Even though, the architecture is less efficient in area requirement is compared to conventional lifting based method. Our work presents a Multiplier less structure which is better when compared to traditional convolution and lifting based DWT architecture. The design reduces the power, some transistors, and a critical path. The proposed model incorporates a pipelining architecture by which the speed can be improved. It predict and update blocks are implemented using adder and shifter for the proposed method. The proposed method is described using Quartos II 9.1 software. The proposed circuit improves power by 56% ofthis system.
