A cryptosystem processor includes a twiddle factor memory, a SRDGT BFU, and a SPN. The twiddle factor memory has ZETA ports. The at least one SRDGT BFU has six input ports and four output ports and switchable among operation in DGT/IDGT/CWM mode, in which two of the input ports electrically communicate with the ZETA ports, respectively. The SRDGT BFU is configured to read and write two data points when working under the DGT/IDGT mode and is configured to read and write four data points when working under the CWM mode. The SPN electrically communicates with the SRDGT BFU and has at least one dual-port BRAM serving as memory cache configured to store polynomial, in which the SPN is configured to support the required number of data points reading or writing per cycle in the DGT/IDGT/CWM mode.

The present invention provides a system for implementing a logistic regression classification mechanism to measure and assess a depth of anesthesia of an animal subject based on electroencephalography (EEG), which includes a signal pre-processor, an epoch generator, a feature extractor, a classifier, and a predictor. Related method of how to pre-process the raw data of EEG signal, epoch generation thereof, feature extraction from each epoch, classification based on extracted features, and prediction of different states of the animal subject based on a prediction decision mechanism is also provided. Classification accuracy of the present invention for 1-second and 10% overlapping epochs is about 94% with an average total system delay of about 12 μs and low on-chip power consumption. The present system is entirely optimized, which leads to a 100% accurate channel prediction after a 7-second run-time on average.
