Abstract
A method and apparatus are disclosed for a multi-processor SoC which includes an execution domain processor for running an execution domain which hosts independent software partitions by accessing, for each software partition, one or more SoC resources; a control point processor that generates control data with pre-emption vectors for controlling access to the SoC resources by identifying at least a first SoC resource that each software partition is allowed to access; and an access control circuit connected between the execution domain and the SoC resources and configured to provide, in response to the control data, a dynamic runtime isolation barrier which enables the execution domain processor to switch between software partitions in response to a pre-emption interrupt trigger by fetching partition instructions from a corresponding pre-emption interrupt vector address in memory that is associated with the pre-emption interrupt trigger.
