Abstract: A display method using a virtual widget, an associated electronic device, and an integrated circuit are provided. The electronic device includes: a display; a plurality of sensors, a first control system; and a second control system having a controller. The first control system offloads display workloads to the second control system before the first control system has entered the sleep mode. The controller receives sensor data from the sensors and executes a virtual widget based on information of the received sensor data when the first control system has entered the sleep mode.

Abstract: Aspects of the disclosure provide a method and an apparatus for executing a program, e.g., a neural network (NN) inference. For example, the apparatus can include an executor and a dynamic loading agent. The executor can be coupled to a second memory, and be configured to execute a portion of the NN inference loaded on the second memory from a first memory that stores the NN inference, and to generate a signal based on a progress of the execution of the NN inference. The dynamic loading agent can be coupled to the executor, the first memory and the second memory, and be configured to load a next portion of the NN inference stored in the first memory to the second memory and to manage power supplied to the first memory based on the signal from the executor and an inference executing scheme stored in the second memory.

Abstract: Aspects of the disclosure provide an apparatus for executing a program that involves a plurality of operators. For example, the apparatus can include an executor and an analyzer. The executor can be configured to execute the program with at least a first one of the operators loaded on a second memory from a first memory that stores the operators and to generate a signal based on a progress of the execution of the program with the first operator. The analyzer can be coupled to the executor, the first memory and the second memory, and configured to load at least a second one of the operators of the program next to the first operator stored in the first memory to the second memory before the executor finishes execution of the program with the first operator based on the signal from the executor and an executing scheme stored in the second memory.
