Electronic circuit for multiply-accumulate operations

A method for performing a multiply-and-accumulate operation, the method comprising:

• performing, by a multiplier circuit, a multiplication of a first input signal with a second input signal, wherein the first input signal is a binary input signal comprising a sequence of input bits;
• receiving, by an oscillator circuit, a result signal of the multiplication from the multiplier circuit;
• providing, by the oscillator circuit, output pulses having an output frequency which is dependent on the result signal of the multiplication;
• counting, by a digital counter circuit, the output pulses;
• providing, by the digital counter circuit, a plurality of counter bits;
• and
• selecting, by the digital counter circuit, one of the plurality of counter bits for incrementation in dependence on a significance of a corresponding input bit of the sequence of input bits.

A design structure tangibly embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit, the design structure comprising an electronic circuit including:

• a multiplier circuit for performing a multiplication of a first input signal with a second input signal, wherein the first input signal is a binary input signal comprising a sequence of input bits;
• an oscillator circuit for receiving a result signal of the multiplication from the multiplier circuit and for providing output pulses having an output frequency which is dependent on the result signal of the multiplication;
• and
• a digital counter circuit for counting the output pulses, the digital counter circuit providing a plurality of counter bits and selecting one of the plurality of counter bits for incrementation in dependence on a significance of a corresponding input bit of the sequence of input bits.
