  • Publication number: 20240154618
    Abstract: A method of optimizing a quantization step size of an analog-to-digital converter (ADC) based on a number of crossbar arrays of a computing device includes: generating a first mapping relationship between the quantization step size of the ADC and a first root mean square error, the first root mean square error reflecting a quantization error and a clipping error, wherein the generating the first graph is based on use of only a single crossbar array; generating a second mapping relationship between the quantization step size of the ADC and a second root mean square error, the second root mean square error reflecting a quantization error, wherein the generating the second mapping is based on a uniform distribution of a total sum of quantization errors; and determining the quantization step size of the ADC based on the first mapping relationship and the second mapping relationship.
