VLSI Computational Architectures for the Arithmetic Cosine Transform
N. Rajapaksha, A. Madanayake, R. J. Cintra +2
The discrete cosine transform (DCT) is a widely-used and important signal processing tool employed in a plethora of applications. Typical fast algorithms for nearly-exact computati…
A Single-Channel Architecture for Algebraic Integer Based 88 2-D DCT Computation
A. Edirisuriya, A. Madanayake, R. J. Cintra +1
An area efficient row-parallel architecture is proposed for the real-time implementation of bivariate algebraic integer (AI) encoded 2-D discrete cosine transform (DCT) for image a…
A Digital Hardware Fast Algorithm and FPGA-based Prototype for a Novel 16-point Approximate DCT for Image Compression Applications
F. M. Bayer, R. J. Cintra, A. Edirisuriya +1
The discrete cosine transform (DCT) is the key step in many image and video coding standards. The 8-point DCT is an important special case, possessing several low-complexity approx…
