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 Row-parallel 88 2-D DCT Architecture Using Algebraic Integer Based Exact Computation
A. Madanayake, R. J. Cintra, D. Onen +4
An algebraic integer (AI) based time-multiplexed row-parallel architecture and two final-reconstruction step (FRS) algorithms are proposed for the implementation of bivariate AI-en…
Multiplierless Approximate 4-point DCT VLSI Architectures for Transform Block Coding
F. M. Bayer, R. J. Cintra, A. Madanayake +1
Two multiplierless algorithms are proposed for 4x4 approximate-DCT for transform coding in digital video. Computational architectures for 1-D/2-D realisations are implemented using…
