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.
