Abstract: A one-dimensional wavelet system and method. In various embodiments, computation engines are set forth for forward and inverse transforms in a wavelet system. The computation engine includes a plurality of register banks having input ports arranged to receive input sample values and a multiplexer coupled to the output ports of the register banks. A processing unit is configured to perform the forward or inverse wavelet transform for data values that are sequenced through the register banks and multiplexer by a control unit. The computation unit is adaptable to implement discrete wavelet transform, discrete wavelet packet, and custom wavelet trees.

Abstract: Two-dimensional discrete wavelet transform analysis and synthesis banks. In various embodiments, a cascade combination of two one-dimensional wavelet transforms is implemented, along with a set of memory buffers between the two stages. The memory buffers store intermediate results between the stages of the two-dimensional discrete wavelet transform, thereby eliminating off-chip memory references.
