Secure Memory Configuration

An application in a data center used for massive data processing is relatively complex and large and may require different memory configurations. However, a conventional solution on a terminal that includes a fixed TEE memory size and a small-capacity secure memory (such as 128 MB) cannot meet service requirements.

To adapt to data center scenarios, this solution allows the administrator to set the size of the TEE secure memory. Currently, a maximum of 512 GB secure memory can be set.

For details about the configuration methods and restrictions, see the BIOS operation manual or "Secure Memory Specifications" in TrustZone Feature Guide.
