Abstract: Provided is a neuromorphic system for synaptic learning in a spiking neural network (SNN)-based neuromorphic array structure. Control blocks including a post-synaptic neuron, which generates a post-neuron spike, are disposed on output lines of a synapse array to implement a spike timing dependent plasticity (STDP) operation such that synaptic learning can be stably implemented in an SNN neuromorphic array. Also, a lateral inhibition circuit may be added. When a post-neuron spike is generated by an STDP control block connected to any one output line, the lateral inhibition circuit inhibits STDP control blocks connected to other output lines from generating spikes. Accordingly, learning selectivity can be improved, and thus the performance of an STDP algorithm can be improved.

Abstract: A biological recording device used to monitor biological electrical activity and a method of recording neural signals. In a preferred embodiment, the biological recording device is a neural probe. The biological recording device includes a probe body with a probe shank and a recording platform that uses a delta (?) modulator and a delta sigma analog to digital converter (?? ADC).

Abstract: A pulse width modulated power converter is presented with load-adaptive power transistor scaling scheme using analog-digital hybrid control. The coarse digital control generates an approximate duty cycle necessary for driving a given load and selects an appropriate width of power transistors to minimize redundant power dissipation. The fine analog control provides the final tuning of the duty cycle to compensate for the error from the coarse digital control. The mode switching between the analog and digital controls is accomplished by a mode arbiter which estimates the average duty cycle for the given load condition from limit cycle oscillations induced by the coarse adjustments.

Abstract: An apparatus and method for detecting program plagiarism through memory access log analysis is provided. A data extractor extracts an access log of an original program and an access log of a target program to be compared with the original program from a memory accessed by the programs. A common string detector enumerates values, which are obtained from the access logs extracted from the original program and the target program, into strings and detects a common string that commonly exists in the strings. A discontinuity calculator calculates a discontinuity value that indicates a distance between the strings by using an array of the detected common strings. A plagiarism determining unit determines that the target program is plagiarized if the calculated discontinuity value is less than a predetermined reference value.
