  • Memory protection mechanisms are essential for automotive microcontrollers to meet safety and security requirements.
  • Current systems use either physical address-based protection (MPU) or virtual address mapping (MMU).
  • Virtual address spaces simplify software development and integration, especially in virtualization contexts.
  • This work proposes an extension to the RISC-V SPMP proposal to enable address redirection while maintaining deterministic behavior.
