System-Wide Security, Implementation of TrustZone, The NS

The CoreLink TZC-400 TrustZone Address Space Controller (TZC-400) is an AMBA compliant System-on-Chip (SoC) peripheral. It performs security checks on transactions to memory or peripherals. You can use the TZC-400 to create up to eight separate regions in the address space, each with an individual security level setting.

Working Subscribe Subscribed Unsubscribe 24.4K The TrustZone® Address Space Controller (TZC) is intended to filter DDR accesses according to security rules and non-secure master address ID. This is a simplified diagram of TZC. TZC is composed of two filter units, one per AXI port. Filters are working concurrently. The two filters are controlled by a common control register The TrustZone Address Space Controller (TZASC) is a programmable unit that enables you to configure memory regions of selected peripherals with different access rights for Secure and Non-secure AXI transactions. The TZASC has 4KB memory space. The Cortex-A9 MPCore test chip design uses one TZASC to secure the SMC peripheral. See Figure 2.3. Setup VPN. Step 1.
