  • Publication number: 20180341303
    Abstract: A system on a chip (SOC) and an integrated circuit device having the same are disclosed. The SOC has a chip controller and a first chip element which do not need to operate according to a reference clock signal, and the SOC has a second chip element which needs to operate according to the reference clock signal. During resetting of a main system processor, the chip controller of the SOC is reset simultaneously. After the chip controller finishes resetting, the first chip element is then reset. After the main system processor finishes resetting, the second chip element of the SOC starts to reset. Accordingly, during the resetting of the main system processor, the SOC is reset simultaneously, thereby reducing the boot time of the integrated circuit device.
