Abstract
A system and method for efficiently performing a bootup operation are described. In various implementations, an integrated circuit includes at least one or more processors and on-chip memory. The on-chip memory has a higher security level than off-chip memory. One of the one or more processors is designated as a security processor. During the processing of the multiple boot steps of a bootup operation, the security processor receives one or more out of band (OOB) events that are not included in the bootup operation. The security processor initializes both an OOB queue and a main boot queue in the on-chip memory. The security processor stores boot steps of the bootup operation in the main boot queue and stores received OOB events in the OOB queue. The security processor executes at least one OOB event prior to completing the bootup operation.
