Data processing method and apparatus, electronic device, and storage medium

A data processing apparatus, comprising:

• an obtaining module, configured to obtain to-be-processed array data;
• a first mapping module, configured to perform first mapping on the to-be-processed array data to obtain target array data, and determine a weight corresponding to each target data in the target array data during the first mapping;
• wherein a numerical range of the target data in the target array data is less than a numerical range of data in the to-be-processed array data;
• an operation module, configured to perform multiplier and accumulation operation on the target data with the weight of 1 according to a first rule to obtain a first operation value;
• and
• perform the multiplier and accumulation operation on the target data with the weight not equal to 1 according to a second rule of multiplying a same column by a same value to obtain a second operation value;
• an analog-to-digital conversion module, configured to perform analog-to-digital conversion on the first operation value and the second operation value to obtain a first quantized value and a second quantized value, respectively;
• a second mapping module, configured to perform second mapping on the first quantized value and the second quantized value based on the weights to obtain a third quantized value and a fourth quantized value;
• wherein the second mapping is reverse to the first mapping;
• and
• a summation module, configured to sum the third quantized value and the fourth quantized value to obtain a target output value.
