Abstract
Disclosed herein are techniques for accelerating convolution operations or other matrix multiplications in applications such as neural network. In one example, an apparatus comprises a first circuit, a second circuit, and a third circuit. The first circuit is configured to: receive first values in a first format, the first values being generated from one or more asymmetric quantization operations of second values in a second format, and generate difference values based on subtracting a third value from each of the first values, the third value representing a zero value in the first format. The second circuit is configured to generate a sum of products in the first format using the difference values. The third circuit is configured to convert the sum of products from the first format to the second format based on scaling the sum of products with a scaling factor.
