Abstract
An SoC includes an execution domain processor for running an execution domain which hosts n partitions by accessing, for each partition, one or more SoC resources; a control point processor that generates control data with n debug enable signals corresponding to the n partitions for controlling access to the SoC resources by identifying at least a first SoC resource that each partition is allowed to access; and an access control circuit to provide, in response to the control data, a dynamic runtime isolation barrier which allows access by the debugging tool to only a specified partition running on the execution domain which has a debug enable signal set to a first active value and prevents access to the other n−1 partitions running on the execution domain, For the partition under debug, the dynamic runtime isolation barrier may block debugger access to selected memory regions accessible by the partition under debug.
