  • Publication number: 20240329929
    Abstract: Embodiments relate to performing multiply-accumulator operation on asymmetrically quantized input data and kernel data in a neural processor. Instead of adjusting to the input data at a multiply-accumulator to account for the asymmetric quantization of the input data, an adjusted bias for the multiply-accumulator operation is computed beforehand and stored in the multiply-accumulator. On the other hand, kernel coefficients derived from the kernel data are adjusted at the multiply-accumulator to account for the asymmetric quantization. In this way, computational complexity associated with asymmetric quantization may be reduced while increasing the efficiency of the convolution operations at the neural processor.

  • Publication number: 20240329933
    Abstract: Embodiments of the present disclosure relate to a multiply-accumulator circuit that includes a main multiplier circuit operable in a floating-point mode or an integer mode and a supplemental multiplier circuit that operates in the integer mode. The main multiplier circuit generates a multiplied output that undergoes subsequent operations including a shifting operation in the floating-point mode whereas the supplemental multiplier generates another multiplied output that does not undergo any shifting operations. Hence, in the integer mode, two parallel multiply-add operations may be performed by the two multiplier circuits, and therefore accelerate the multiply-adder operations. Due to the lack of additional shifters associated with the supplemental multiplier circuit, the multiply-accumulator circuit does not have a significantly increased footprint.
