BP141 TrustZone Mem. Adapter

The BP141 TrustZone Memory Adapter (TZMA) is an AMBA compliant System-on-Chip peripheral that enables a single physical memory cell of up to 2MB to be shared between a secure and a non-secure partition. It is compatible with the AXI internal memory interface (BP140).

The TrustZone Protection Controller (TZPC) sets up memory areas as secure or non-secure.

Transactions presented at the AXI slave interface are checked against the current security configuration. If a transaction passes this security check then it is routed through to the AXI master interface.
