US Patent 11188300 Preparation and execution of quantized scaling on integrated circuitry

Preparation and execution of quantized scaling may be performed by operations including obtaining an original array and a scaling factor representing a ratio of a size of the original array to a size of a scaled array, determining, for each column of the scaled array, a horizontal coordinate of each of two nearest elements in the horizontal dimension of the original array, and, for each row of the scaled array, a vertical coordinate of each of two nearest elements in the vertical dimension of the original array, calculating, for each row of the scaled array and each column of the scaled array, a linear interpolation coefficient, converting each value of the original array from a floating point number into a quantized number, converting each linear interpolation coefficient from a floating point number into a fixed point number, storing, in a memory, the horizontal coordinates and vertical coordinates as integers, the values as quantized numbers, and the linear interpolation coefficients as fixed point numbers.
