BP147(TZPC) and TZC-380

chinatiger


hi, experts:

TZC-380 : TZ Address Space Controller

It could control dram regions more detailed than BP147(TZPC).

So:

Will BP147 be deprecated?

Or these 2 IPs have different usuage?

best wishes,

    Hi,

    Recently ARM has developed TZC-400 to provide security protection for different regions of DRAM.

    TZC-400 supersedes TZC-380.

    TrustZone Controllers - ARM

    TZC-400 features include

    - support for 1, 2 or 4 pass through AMBA interfaces (AXI3, AXI4 or ACE-Lite)

    - security for 8 different regions

    - support for DRM usecases with a protected video path

    - fast path for low latency masters

    - support for larger numbers of outstanding transactions (up to 256)

    I hope this helps with your investigations into TrustZone IP!
