AI Technical Summary

Technical Problem

Existing embedded MCU systems struggle to achieve hardware virtualization in resource-constrained scenarios, and the core code and business logic are not fully isolated, resulting in an unsafe and unreliable operating environment.

Method used

By employing privileged simulators, virtual memory simulators, and general system components, and setting different working modes and physical storage protection mechanisms, memory isolation is achieved, simulating independent processing units to handle privileged instructions and memory access requests, ensuring security and reducing performance loss.

Benefits of technology

It achieves an MMU-like effect on MCU processors without an MMU, providing a safer and more reliable embedded MCU software operating environment suitable for complex embedded MCU scenarios.

Abstract

This invention discloses an embedded MCU system, method, electronic device, and storage medium. The embedded MCU system includes a privileged simulator, a virtual memory simulator, system general components, and at least one user application. The privileged simulator, virtual memory simulator, and system general components operate in a first working mode, while the user application operates in a second working mode. The privileged simulator handles each user application, and a privileged simulator instance is set up for each user application. Each privileged simulator instance simulates an independent processing unit. All memory accesses are intercepted through a PMP mechanism. When a user application requests memory access, the virtual memory simulator handles the memory access, thereby achieving memory isolation between user applications. This invention provides a feasible software isolation scheme in embedded MCU scenarios, offering a more secure and reliable operating environment for complex embedded MCU software scenarios.
