ABSTRACT:
The invention provides an integrated systolic architecture which can perform both forward and inverse Discrete Wavelet Transforms with a minimum of complexity. A plurality of processing cells, each having an adder and a multiplier, are coupled to a set of multiplexers and delay elements to selectively receive a single input datastream in the forward DWT mode and two datastreams in the inverse DWT mode. In the forward DWT mode, the integrated architecture decomposes the input datastream into two output sequences--a high frequency sub-band output and a low frequency sub-band output. In the inverse DWT mode, the integrated architecture reconstructs the original input sequence by outputting even terms and odd terms on alternating clock cycles. As a result, the architecture can achieve 100% utilization and is suitable to be implemented in VLSI circuitry.
