Abstract: Provided is a method of operating a system-on-chip (SoC) including a plurality of CPUs. The method includes: receiving a debug request by a first CPU of the CPUs; outputting a first signal to the CPUs by the first CPU in response to the debug request; selecting a second CPU from the CPUs to control the debugging based on the first signal; and performing a debug operation by selecting a debug target block by the second CPU.
