Abstract: This application describes hybrid hardware accelerators, systems, and apparatus for performing various computations in neural network applications using the same set of hardware resources. An example accelerator may include weight selectors, activation input interfaces, and a plurality of Multiplier-Accumulation (MAC) circuits organized as a plurality of MAC lanes Each of the plurality of MAC lanes may be configured to: receive a control signal indicating whether to perform convolution or vector operations; receive one or more weights according to the control signal; receive one or more activations according to the control signal; and generate output data based on the one or more weights and the one or more input activations according to the control signal and feed the output data into an output buffer. Each of the plurality of MAC lanes includes a plurality of multiplier circuits and a plurality of adder-subtractor circuits.

Abstract: The present application has disclosed a substrate grinding device, which includes a carrying platform, a lifting platform and a grinding head, the lifting platform is located above the carrying platform and configured to be movable in a direction perpendicular to an upper surface of the carrying platform with respect to the carrying platform upwardly or downwardly; and the grinding head is mounted to the lifting platform and configured to grind a grind region of a substrate to be ground disposed on the carrying platform, the grind region being a region of the substrate where there is a partial scratch.
