Abstract
Provided are a processing device and a method for secure booting thereof, in which the processing device includes a security core that operates a Root of Trust and sequentially performs an integrity check on first firmware and second firmware through the Root of Trust, a main core that sequentially operates the first firmware and the second firmware, a non-volatile memory storing the first firmware and the second firmware, and a first volatile memory that loads the first firmware and the second firmware from a main core domain of the main core and operates the loaded firmware with the main core.
