RESOURCE ACCESS SECURITY FOR MULTIPLE SOFTWARE CONTEXTS
In described examples, a processor system includes a mailbox, a hardware security functional block (HSFB, also called a trusted agent herein), a processor, and a processor firewall. The HSFB includes a database configured to store at least one software context access rule. The processor executes mul...

| description | In described examples, a processor system includes a mailbox, a hardware security functional block (HSFB, also called a trusted agent herein), a processor, and a processor firewall. The HSFB includes a database configured to store at least one software context access rule. The processor executes multiple software contexts. The HSFB approves or denies an access request received from a debugging tool, via the mailbox, in response to the database and a software context identification (ID) included in the access request. The HSFB sends a message to the processor firewall indicating whether the access request is approved. The processor firewall determines whether to pass instructions to the processor for execution with respect to the identified software context in response to the message. |
