Utilizing a processor's memory management (MMU) facilities, INTEGRITY builds a firewall between the kernel and user tasks that prevents errant or malicious code from corrupting other user tasks or the kernel. INTEGRITY delivers maximum responsiveness and determinism by running with interrupts continuously enabled and guaranteeing access to the CPU and memory for critical tasks.
