A fetch process for a computing system is described herein. The computing system comprises a non-transitory memory. In the non-transitory memory, instructions are stored in Cycle-Redundancy Blocks (CRC blocks). Each of these CRC blocks comprises a first CRC code associated with the instructions stored in the CRC block. During a fetch process, the computing system generates a second CRC code based on the instructions stored in the CRC block and compares the second CRC code with the first CRC code to ascertain the success of the fetch process.

Systems and methods for fetching and writing instructions to memory

A method for accelerating sleep startup speed is provided. The method may include determining that a system-on-chip (SoC) is under a sleep mode; determining that a wake-up condition is met; calculating a second authentication key based on data stored in a flash memory of the SoC using a cryptographic algorithm; comparing the second authentication key with a first authentication key, wherein the first authentication key is associated with a secure boot of the SoC and obtained from an Always On (AON) memory of the SoC; and in response to a comparison result that the first authentication key is the same as the second authentication key, waking the SoC up from the sleep mode.

Method for accelerating deep sleep startup speed in IoT

A method for resisting fault injection attacks during secure boot is provided. The method may include: performing a secure check on a System-on-Chip (SoC), wherein one or more pre-determined values are written on one or more bits of a first register of the SoC during the secure check; reading one or more corresponding bits of a second register of the SoC; and comparing the values of the one or more bits of the second register with the values of the one or more corresponding bits of the first register. In response to a comparison result that the values of the one or more bits of the second register are the same as the values of the one or more corresponding bits of the first register, the SoC is booted.
