  • Security subsystem for execution verification
    Patent number: 12450342
    Abstract: Techniques for providing execution verification at an integrated circuit device are described. The integrated circuit device may include a processor core configured to execute instructions. The integrated circuit device may also include a trace block configured to extract an execution trace from the processor core, the execution trace indicating the instructions that have been executed by the processor core. The integrated circuit device may further include a verification core configured to receive the execution trace from the trace block, extract an address from a control transfer instruction in the execution trace, perform one or more checks on the address, and generate an alarm signal based on the one or more checks.
