Abstract: Embodiments relate to a neural processor circuit with scalable architecture for instantiating one or more neural networks. The neural processor circuit includes a data buffer coupled to a memory external to the neural processor circuit, and a plurality of neural engine circuits. To execute tasks that instantiate the neural networks, each neural engine circuit generates output data using input data and kernel coefficients. A neural processor circuit may include multiple neural engine circuits that are selectively activated or deactivated according to configuration data of the tasks. Furthermore, an electronic device may include multiple neural processor circuits that are selectively activated or deactivated to execute the tasks.

Abstract: Embodiments relate to a compiler. The compiler decreases data fetch and read associated with storing data in a data buffer of a neural processor circuit to or from a system memory. The data buffer can store an input slice of data for processing by a neural engine(s) of the neural processor circuit, an output slice of data output from the neural engine(s), and/or an intermediate data slice of data.
