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.

2020-6-17 · TrustZone splits CPU into normal world and secure world, all other hardware resources are split as well. Each world has its own user and kernel space, and can switch to each other by smc instruction. Only the normal world has virtualization support.
