摘要： Various methods and apparatuses of protection mechanism are described. A target intellectual property block may field and service requests from an initiator intellectual property block in a system-on-chip network. The target intellectual property block has an associated protection mechanism with logic configured to restrict access for the requests to the target intellectual property block. The request's access is restricted based on access permissions associated with a region within the target intellectual property block and attributes of the request trying to access that region.
