Hardware realization of direct subband transformer with minimum used resources

Hardware realization of direct subband transformer with minimum used resources State-of-the-art direct subband transformer implementations employ significant amount of memory resources for the realization of synchronization memory banks between different levels of the decomposition. This paper presents a hardware realization of direct subband transformer without synchronization memory banks between different levels of the decomposition. Such realization achieves significant savings in both memory and logic resources. The proposed realization also provides significant savings in time resources due to a minimum delay which direct subband transformer introduces into an image compression system.
