Abstract :
This paper presents the FPGA implementation of a processor suitable for adaptive multi-resolution analysis in a audio coding schema. Implementation takes into account all symmetries in the filter response and uses distributed arithmetic approach in order to reduce the device cells account and routing requirements. The prototyped circuit allows dynamic reconfiguration of subbands number and width
