This paper presents a high speed, non-pipelined FPGA implementation of the Rijndael algorithm (Daemen, 1999), which has been selected as the new AES algorithm by the National Institute of Standards and Technology (NIST). In this study, we have implemented both the encryption and the decryption algorithms of Rijndael on the same FPGA. All the key and data(More)
Measuring complexity of dynamical systems is a mighty tool for electrophysiological signal processing. There are plenty of entropies for estimating complexity measure. Approximate entropy (ApEn), sample entropy (SampEn), fuzzy entropy (FuzzyEn), wavelet entropy (WE) and wavelet packet entropy (WPE) was used for surface EMG feature extraction for face(More)
In this paper, to decrease the computational cost and number of cycles in Template Matching Algorithm, a novel two-stage algorithm is proposed. The Sum of Absolute Differences method is used for matching. The proposed algorithm is implemented on Field-Programmable-Gate-Array (FPGA). The algorithm is accelerated with the effective usage of Block RAMs(More)
We assessed clinical features as well as sensory and motor recoveries in 3 full-face transplantation patients. A frequency analysis was performed on facial surface electromyography data collected during 6 basic emotional expressions and 4 primary facial movements. Motor progress was assessed using the wavelet packet method by comparison against the mean(More)
