Abstract
An SoC device has a boot-code memory that stores boot code and a boot core that accesses the boot-code memory to execute the boot code at startup. The boot core is capable of executing application code after the startup is complete. One or more master cores execute application code. An access control circuit prevents the boot core from accessing the boot-code memory when application code is being executed.
