title: Texas Instruments' Secure Proxy
maintainers:

description: |
The Texas Instruments' secure proxy is a mailbox controller that has
configurable queues selectable at SoC(System on Chip) integration. The
Message manager is broken up into different address regions that are
called "threads" or "proxies" - each instance is unidirectional and is
instantiated at SoC integration level by system controller to indicate
receive or transmit path.
