Abstract
An integrated circuit including memory to store image data and filter weights, and a plurality of multiplier-accumulator execution pipelines, each multiplier-accumulator execution pipeline coupled to the memory to receive (i) image data and (ii) filter weights, wherein each multiplier-accumulator execution pipeline processes the image data, using associated filter weights, via a plurality of multiply and accumulate operations. In one embodiment, the multiplier-accumulator circuitry of each multiplier-accumulator execution pipeline, in operation, receives a different set of image data, each set including a plurality of image data, and, using filter weights associated with the received set of image data, processes the set of image data associated therewith, via performing a plurality of multiply and accumulate operations concurrently with the multiplier-accumulator circuitry of the other multiplier-accumulator execution pipelines, to generate output data. Each set of image data includes all of the image that correlates to the output data generated therefrom.
