A system-on-chip (SoC) includes a slave intellectual property (IP) block, a master IP block, and an update control unit. The slave IP block is configured to perform first processing on first data based on first control information stored in a first storage unit. The master IP block is configured to perform second processing on second data in response to receiving a first processing result obtained by performing the first processing on the first data. Performing the second processing is based on second control information stored in a second storage unit. The update control unit is configured to determine an update time of the first control information or an update time of the second control information in response to performing the first processing and performing the second processing.
