ARM Inc. TrustZone Address Space Controller TZC-380

Description
Secure system IP blocks to support the ARM TrustZone™ system-wide approach to security in preventing access by malicious software to selected memory regions and peripherals such as screens and keypads. The TrustZone Address Space Controller (TZC-380) extends on-chip security to protect multiple regions of external memory from software attack. TrustZone on-chip memory TrustZone Boot ROM, 8-16KB for signature check code On-chip memory (e.g. TCM) – 2KB instruction and 100 bytes data for Secure Monitor On-chip RAM for secure code and data. TrustZone Internal Memory Wrapper (PL141) can partition a single larger on-chip RAM into Secure and Non-Secure) Worlds TrustZone off-chip memory TrustZone RAM - in DDR memory - typically 256K-1M for decrypted/checked code. Off-chip memory cheaper per bit Partitioning a single off-chip memory in upto 16 secure regions by TrustZone Address Space Controller (TZC-380). Resistant to software attack.
