The block diagram of the pipelined residue-to-binary converter for the three-channel RNS-based DWT, P₇={127,128,255}. Four identical 2ⁿ⁺¹−1 MAs, three subtractors and two multiplexers are generally required for RBC. Two shift registers are used for extending the 7-bit input by one bit. In the real implementation this operation does not add any cost because this operation is just equivalent to appending 0 at the first location of the input signal
