Crossbar Array Apparatus based on C- TSVD(Compressed-Truncated Singular Value Decomposition), and Analog MAC(Multiply-Accumulate) operation method using the apparatus

摘要

The technical idea of the present invention is to provide a C-TSVD-based array device and an analog MAC operation method using the device, which can reduce the number of sub-arrays in an array division while minimizing deterioration in accuracy and latency of reasoning. The C-TSVD based array device comprises an original crossbar array in the form of an m x n matrix, or the two partial crossbar arrays; an ADC for AD-converting output values of column output lines of each of the sub-arrays of the original crossbar array or the two partial crossbar arrays; an adder for summing the results of the ADC corresponding to the column output lines; and a controller controlling the application of the original crossbar array, or the two partial crossbar arrays, corresponding to one layer of a neural network in neuromorphic computing, An input value is input to the row input lines, a weight is multiplied by the input value, and an accumulated result is output as an output value of the column output lines, and the weight is the original crossbar array or the two partial crossbar arrays respond to
