MULTIPLE LEVEL SOC RESOURCE ALLOCATION AND ISOLATION SYSTEM AND METHOD

An SoC with a multiple level resource isolation system including initiator devices that conduct transactions with addressed slave devices via an interconnect, access identifier assignment (AIDA) devices that append an access identifier (AID) including a group identifier (GID) and a domain identifier (DID) to each transaction of a corresponding initiator device, access control (AC) devices that control access to slave devices based on an AID provided with a transaction, a partition manager that programs GIDs into the AIDA and AC devices for assigning slave devices to groups, and group managers that program DIDs into the AIDA devices for each matching GID programmed therein, and that program the AC devices with access rights to one or more DIDs for each slave device assigned to a corresponding group with a matching GID programmed therein.
