Abstract
A neural processor includes neural engines for performing convolution operations on input data corresponding to one or more tasks to generate output data. The neural processor also includes a data processor circuit coupled to external system memory. The data processor circuit includes a buffer for storing the output data from the neural engines. The neural processor further includes a task manager coupled to the data processor circuit. The task manager receives a context-switch task. The context-switch task specifies a switch of the data processor circuit from handling an outgoing task to an incoming task. The task manager sends configuration data of the context-switch task to cause the data processor circuit to transmit the output data corresponding to the outgoing task from the buffer to the external system memory. The data processor circuit also fetches data corresponding to the incoming task from the external system memory to the buffer.
