This work targets the challenging issue to produce high throughput and low-cost configurable architecture of Discrete wavelet transforms (DWT). More specifically, it proposes a new hardware architecture of the first and second generation of DWT using a modified multi-resolution tree. This approach is based on serializations and interleaving of data between different stages. The designed architecture is massively parallelized and sharing hardware between low-pass and high-pass filters in the wavelet transformation algorithm. Consequently, to process data in high speed and decrease hardware usage. The different steps of the post/pre-synthesis configurable algorithm are detailed in this paper. A modulization in VHDL at RTL level and implementation of the designed architecture on FPGA technology in a NexysVideo board (Artix 7 FPGA) are done in this work, where the performance, the configurability and the generic of our architecture are highly enhanced. The implementation results indicate that our proposed architectures provide a very high-speed data processing with low needed resources. As an example, with the parameters depth order equal 2, filter order equal 2, order quantization equal 5 and a parallel degree P = 16, we reach a bit rate around 3160 Mega samples per second with low used of logic elements ( ≈ 400) and logic registers ( ≈ 700 ).

“…The first work related to the hardware implementation of DWT was recorded in 1994 [8] Denk and Parhi described an orthonormal DWT architecture, which used a lattice Quadrature Mirror Filters (QMF) structure and digit-serial processing techniques. Similarly, Hatem et al [9] proposed a parallel/sequential QMF architecture in VLSI for the DWT, to reduce the overall numbers of multipliers. After that, the research evolution was started.…”

This work presents new pipeline-parallel, generic and configurable parallel hardware architectures for the Direct/Inverse Wavelet Packet Transform (DWPT/IDWPT) independent of any specific family of wavelets, implemented in FPGA technology using a parallel architecture of direct FIR filter. We propose in the following paper, new P-parallel structures for the DWPT and IDWPT transforms based on the Mallat binary tree algorithm. Therewith, we developed a P-parallel/modified direct FIR filter architecture using pipelineparallelize and hardware resource sharing, which provides not only ultra-high speed data processing but also a limited amount of hardware as resources are shared between filters and the bidirectional wavelet packet transformation. This model follows two important strategies: I) a powerful structure pipeline/P-parallel using strict data management and interleaving, II) sharing hardware at different levels in the transformation and between the two DWPT/IDWPT transformations. These architectures are modeled in VHDL at RTL modeling level. They are generic and fully configurable: at synthesis and post-synthesis. The simulation results show an acceleration of data processing to an approximate value of P-Parallel multiplied by frequency with lower used resources. Furthermore, the impact of tree depth and filters order on throughput is very light due to the linearize architecture of our model. The synthesis was achieved using the Intel Quartus Prime Lite Edition software and targeting the Intel Altera Cyclone FPGA technology.

This paper represents the hardware implementation of high speed DWT using details of 5/3 wavelet filters for image compression applications. Wavelets also find application in speech compression, which reduces transmission time in mobile applications. The main aim of this work was to show that great complexity reduction with excellent performance can be achieved by multiplier less implementation of DWT on FPGA using 5/3 wavelet filters. DWT performs multiresolution analysis which enables to have a scale-invariant interpretation of image. To optimize high speed and memory requirement, we propose novel VLSI architecture for 2D DWT using Conditional Carry Adder.
