An integrated circuit includes intellectual property (IP) processing circuitries each including a separate, respective at least one scan chain, and temperature management controller circuitry configured to transmit an input pattern including a plurality of bits to at least one scan chain of a first IP processing circuitry among the IP processing circuitries, detect a temperature of the first IP processing circuitries based on an output pattern received from the at least one scan chain in response to the input pattern being transmitted to the at least one scan chain of the first IP processing circuitry, and control at least one of an operation frequency or an operation voltage of the first IP processing circuitry based on the detected temperature of the first IP processing circuitry.

Systems on chips, integrated circuits, and operating methods of the integrated circuits

In one embodiment, the integrated circuit includes a clock generator configured to selectively generate a first clock; a processor configured to perform operations; and a clock management circuit. The clock management circuit is configured to receive clock management information from the processor and selectively generate a second clock based on the clock management information and the first clock. The processor is configured to perform some operations based on the second clock.
