MMAC (matrix-multiply-accumulate) units are used in consumer brand GPUs for neural network based upsampling of video game resolutions , in professional brands for upsampling of images and videos, and in server brand GPUs for accelerating convolutional neural networksin general. Convolutions can be implemented as an a series of matrix-multiplications via Winograd-transformations <ref>[https://talkchess.com/forum3/viewtopic.php?f=7&t=66025&p=743355#p743355 Re: To TPU or not to TPU...] by [[Rémi Coulom]], [[CCC]], December 16, 2017</ref>. Mobile SoCs usually have an dedicated neural network engine as MMAC unit.
