Abstract: A system on chip includes a secure processing unit (SPU), an artificial intelligence/machine learning accelerator (AI/ML accelerator), a memory inline cypher engine, and a central processing unit (CPU). The SPU is used to store biometrics of users. The AI/ML accelerator is used to process images, and analyze the biometrics of users. The AI/ML accelerator includes a micro control unit (MCU) for intelligently linking access identifications (IDs) to version numbers (VNs). The inline cypher engine is coupled to the AI/ML accelerator and the SPU for receiving a register file from the MCU, encrypting data received from the AI/ML accelerator, and comparing the biometrics of the users received from the SPU with the data. The CPU is coupled to the SPU and the AI/ML accelerator for controlling the SPU and the AI/ML accelerator.
