Abstract
A system-on-chip (SoC) includes an application processor (AP) including a secure module and a non-secure module, a communication processor (CP), a volatile memory having a first area accessible by the CP, a second area accessible by only the AP, and a third area accessible by the CP and the AP, and non-volatile memory storing a boot loader and a firmware image. Upon power-up of the SoC, the AP copies the boot loader and firmware image from the non-volatile memory to the first area using the non-secure module, switches the first area from a normal mode to a secure mode using the secure module, and verifies integrity of the first firmware image to activate a reset signal. The CP then performs a CP boot operation using the boot loader and firmware image stored in the first area in response to the activated reset signal.
