System and method for security-aware master

摘要

A security-aware master is provided, such that a master can determine its security state before attempting access to secure resources or before requesting secure access level. An exemplary system include a system interconnect; one or more masters coupled with the system interconnect; and a master security check register coupled with the system interconnect. The master security check register is configured to receive a request from a master via the system interconnect to access the master security check register, wherein the request includes a master operating state signal that indicates a security state of the master requesting access, and return a data value to the master based on the master operating state signal, wherein the data value indicates a current security state of the master requesting access.
