Implementation of VLSI on Signal Processing-Based Digital Architecture Using AES Algorithm

Abstract

Continuous improvements in very-large-scale integration (VLSI) technology and design software have significantly broadened the scope of digital signal processing (DSP) applications. The use of application-specific integrated circuits (ASICs) and programmable digital signal processors for many DSP applications have changed, even though new system implementations based on reconfigurable computing are becoming more complex. Adaptable platforms that combine hardware and software programmability efficiency are rapidly maturing with discrete wavelet transformation (DWT) and sophisticated computerized design techniques, which are much needed in today's modern world. New research and commercial efforts to sustain power optimization, cost savings, and improved runtime effectiveness have been initiated as initial reconfigurable technologies have emerged. Hence, in this paper, it is proposed that the DWT method can be implemented on a fieldprogrammable gate array in a digital architecture (FPGA-DA). We examined the effects of quantization on DWT performance in classification problems to demonstrate its reliability concerning fixed-point math implementations. The Advanced Encryption Standard (AES) algorithm for DWT learning used in this architecture is less responsive to resampling errors than the previously proposed solution in the literature using the artificial neural networks (ANN) method. By reducing hardware area by 57%, the proposed system has a higher throughput rate of 88.72%, reliability analysis of 95.5% compared to the other standard methods.

Significance of Mathematics in VLSI Circuit Design

“…This includes the manipulation of matrices and vectors representing the signal values, as well as the solving of systems of equations that model the behavior of signals. [9] In VLSI design, linear algebra can be used in signal processing to optimize the design of analog circuits such as filters.One example of using linear algebra in signal processing is in the use of state-space representation for designing filters. State-space representation is a method for representing linear systems using a set of first-order differential equations.…”
