Abstract: A multi-bio-signal-based geriatric cognitive impairment diagnosis method includes collecting multiple bio-signals including brain waves, heart rate variability, and gait measurement values of a subject during walking; calculating a probability value of a geriatric cognitive impairment disease by using a cognitive impairment diagnosis model, based on the multiple bio-signals; and determining whether there is a geriatric cognitive impairment disease, based on a calculated probability value, wherein the cognitive impairment diagnosis model is a model constructed by applying brain waves, heart rate variability, and gait measurement values of a patient with a geriatric cognitive impairment disease to a logistic function.

Abstract: A method of processing data includes: generating at least one partial summed area table (SAT) by dividing data stored in a global memory, and obtaining a row sum and a column sum of each of the at least one partial SAT; performing propagation on the obtained row sums and column sums; when a process of utilizing the SAT is executed, completing at least a partial area of the SAT necessary for the process based on the at least one partial SAT, and the row sums and column sums on which the propagation has been performed; and performing the process by using the completed partial area.
