This paper addresses the design of a partly-parallel cascaded FFT-IFFT architecture that does not require any intermediate buffer. Folding can be used to design partly-parallel architectures for FFT and IFFT. While many cascaded FFT-IFFT architectures can be designed using various folding sets for t…
The ring-learning with errors (R-LWR) problem is utilized to build many ciphers resisting quantum-computing attacks and fully homomorphic encryption that allows computations to be carried out on encrypted data. Modular multiplication of long polynomials with large coefficients is the most critical o…
Hyperdimensional (HD) computing holds promise for classifying two groups of data. This paper explores seizure detection from electroencephalogram (EEG) from subjects with epilepsy using HD computing based on power spectral density (PSD) features. Publicly available intra-cranial EEG (iEEG) data coll…
Blind source separation (BSS) using independent component based analysis (e.g., probabilistic ICA and infomax ICA) have been studied in-depth to extract common hemodynamic sources for a group of functional magnetic resonance images (fMRI). The inherent assumption here is that the sources must be non…
Design of integrated circuits that cannot be reverse engineered is very important for protecting the intellectual property of owners. Integrated circuits can be obfuscated by introducing several modes into the control flow. Only one of the modes is the desired mode and other modes represent either m…
This paper presents novel architectures for linear-phase FIR digital filters using stochastic computing. Stochastic computing systems require fewer logic gates and are inherently fault-tolerant. Thus, these structures are well suited for nanoscale CMOS technologies. Compared to direct-form linear-ph…
The Fast Fourier transform (FFT) is an important operation in digital signal processing applications. In applications such as biomedical signal processing, the signals are real. The real-valued signals exhibit conjugate symmetry, giving rise to redundant values in the outputs. This property can be e…
