Common architecture for discrete wavelet transform analysis and synthesis with sequential and constant processing elements
Pedro Henrique Cox, Aparecido Augusto de Carvalho · 2004
This paper addresses the problem on processing biological data such as cardiac beats, audio and ultrasonic range, calculating wavelet coefficients in real time, with processor clock running at frequency of present ASIC's and FPGA. The parallel filter architecture for DWT has been improved, calculating wavelength coefficients in real time with hardware reduced to 60%. The new architecture, which also processes IDWT, is implemented with the Radix-2 or the Booth-Wallace constant multipliers. Including series memory register banks, one integrated circuit signal analyzer, ultrasonic range, is presented.
