Journal ArticleDOI
Annihilation-reordering look-ahead pipelined CORDIC-based RLS adaptive filters and their application to adaptive beamforming
TL;DR: The novel annihilation-reordering look-ahead technique is proposed as an attractive technique for pipelining of Givens rotation (or CORDIC)-based adaptive filters and is employed to develop fine-grain pipelined QR decomposition-based RLS adaptive filters.
Proceedings ArticleDOI
Automated localization of cysts in diabetic macular edema using optical coherence tomography images
TL;DR: A novel automated system that localizes cysts in optical coherence tomography images of patients with diabetic macular edema (DME) achieves 90% correlation between the estimated cystoid area and the manually marked area, and a mean error of 4.6%.
Proceedings ArticleDOI
Area efficient parallel decoder architecture for long BCH codes
Yanni Chen,Keshab K. Parhi +1 more
TL;DR: A novel group matching scheme is proposed to reduce the overall hardware complexity of both Chien search and syndrome generator units by 46% for BCH(2047, 1926, 23) code as opposed to only 22% if directly applying the iterative matching algorithm.
Journal ArticleDOI
A fast radix-4 division algorithm and its architecture
H.R. Srinivas,Keshab K. Parhi +1 more
TL;DR: The architecture presented for the proposed algorithm is faster than previously proposed radix-4 dividers, which require at least four digits of the partial remainder to be observed to determine quotient digits.
Journal ArticleDOI
High-speed VLSI arithmetic processor architectures using hybrid number representation
H.R. Srinivas,Keshab K. Parhi +1 more
TL;DR: In this article, the authors propose newshifted remainder conditioning, and sign multiplexing techniques in combination with novel circuit architecture approaches to obtain efficient divider and square-root architectures.
