Abstract

A system generally relating to an SoC, which may be a field programmable SoC (“FPSoC”), is disclosed. In this SoC, dedicated hardware includes a processing unit, a first internal memory, a second internal memory, an authentication engine, and a decryption engine. A storage device is coupled to the SoC. The storage device has access to a boot image. The first internal memory has boot code stored therein. The boot code is for a secure boot of the SoC. The boot code is configured to cause the processing unit to control the secure boot.
