Latest Patents
Roussel's latest patents include innovative designs for secure modes in processors that support memory management units (MMUs) and interrupts. His first patent describes a digital system that incorporates a secure mode with three levels of privilege. This mode is designed to operate non-invasively on a processor system, which includes a processor core, instruction and data caches, a write buffer, and an MMU. The secure execution mode ensures that only the code stored in ROM is trusted, while the operating system and native applications are not. This design allows for virtual addressing when the MMU is enabled and provides mechanisms for managing system interruptions.
His second patent further elaborates on the secure mode for processors, emphasizing the dynamic entry and exit capabilities of the secure execution mode. The system monitors specific entry conditions related to caches, write buffers, and the MMU. It also includes structured activation and exit sequences to ensure a safe transition between secure and non-secure environments.
