Provided is a semiconductor device including a target circuit, a monitoring circuit, and a voltage controller. The target circuit includes a transistor. The monitoring circuit is configured to measure a temperature of the target circuit or measure a delay time between an input and an output of the target circuit. The voltage controller is configured to adjust a driving voltage for driving the target circuit or a back-bias voltage for adjusting a threshold voltage of the transistor by referring to at least one of the temperature and the delay time. As the temperature increases, the delay time decreases.

Semiconductor device and operation method thereof

Provided is a network-on-chip (NoC). The NoC includes a plurality of routers configured to receive power through each corresponding power gating switch, and a controller configured to control a power gating switch of each of the plurality of routers based on temperature information provided from each of the plurality of routers and control a driving clock of the plurality of routers. The controller controls the power gating switch to turn off at least one first router by referring to the temperature information and over-scale a clock frequency of at least one turned-on second router.

Network-on-chip using temperature-effect-inversion and operation method thereof

Provided is a video providing system. The video providing system includes a memory configured to store device information of a display device, an analyzer configured to receive an original video from the outside and analyze images in the original video, and a processor configured to generate, from the original video, video streams according to a streaming mode and control signals of the display device respectively corresponding to the video streams, based on device information of a display device and analysis information from the analyzer, and provide the video streams and the control signals to the display device.

Method and system for providing video

An Ultra Low Voltage (ULV) digital circuit includes a logic circuit comprising a plurality of logic gates and a plurality of buffered interconnects for connecting between the plurality of logic gates, a temperature sensor configured to detect a temperature of the logic circuit, and a voltage controller configured to control a driving voltage provided to the logic circuit in order to reduce a power consumption of the logic circuit based on the detected temperature. Each of the plurality of logic gates and buffered interconnects reduces a signal delay as a temperature increases.
