Abstract
A multiplier array for implementing a multiply-accumulate operation has a plurality of rows, where each row comprises multiplexer circuitry and adder circuitry, the multiplexer circuitry selecting, in dependence on a control input, one of a first multiplexer input value and a second multiplexer input value to provide as a first adder input value to the adder circuitry. In each row other than an initial row, the adder circuitry also receives as a second adder input value at least a portion of a result value produced in a preceding row. In a multiplication mode, the multiplier array implements the multiply-accumulate operation, and in a linear interpolation mode, the multiplier array implements a linear interpolation operation between a lower limit value and an upper limit value based on a weighting value.
