  • DISTRIBUTED DYNAMIC MEMORY MANAGEMENT UNIT (MMU)-BASED SECURE INTER-PROCESSOR COMMUNICATION
    Publication number: 20150067287
    Abstract: A first processor and a second processor are configured to communicate secure inter-processor communications (IPCs) with each other. The first processor effects secure IPCs and non-secure IPCs using a first memory management unit (MMU) to route the secure and non-secure IPCs via a memory system. The first MMU accesses a first page table stored in the memory system to route the secure IPCs and accesses a second page table stored in the memory system to route the non-secure IPCs. The second processor effects at least secure IPCs using a second MMU to route the secure IPCs via the memory system. The second MMU accesses the second page table to route the secure IPCs.
