Claim 17:
18. An electronic device, comprising:
system memory configured to store a neural network; and
a neural processor circuit for accelerating processing of the neural network, the neural processor circuit comprising a multiply-add (MAD) circuit and an accumulator circuit, the MAD circuit comprising a shift register and an exponent adder that are used in a floating point mode, the neural processor circuit configured to:
receive fixed point input data and a fixed point kernel coefficient in a fixed point mode;
deactivate the shift register and the exponent adder;
multiply the fixed point input data and the fixed point kernel coefficient to generate a multiplied value; and
generate an output data by accumulating one or more multiplied values generated by the MAD circuit.
