Application: Method and system for preventing unauthorized processor mode switches (Patent ID: US20230342502A1)
The patent filed by Texas Instruments Inc. describes a system with a processor that can activate multiple security levels and a monitoring device that enforces security rules related to these levels. If the processor activates the security levels in a manner that violates the security rules, the monitoring device restricts the system's usage. The electronic device outlined in the claims includes a processor that can operate in secure and non-secure modes, with a register indicating the current mode. The device has separate buses for instructions and data, preventing the fetching of non-secure instructions in secure mode.
Furthermore, the apparatus described in the patent includes monitoring logic, such as a state machine, to prevent the fetching of non-secure instructions when the processor is in secure mode. The system also includes an intermediate mode for transitioning between secure and non-secure modes, with protective actions, like a power reset, triggered in case of security violations. The apparatus's memory system stores secure and non-secure instructions and data separately, ensuring secure operation based on the processor's mode.
