Overlapped boot task fetches and boot task execution to reduce boot time in an electrical device

摘要

In accordance with at least some embodiments, a system includes a first processor and a second processor. The system also includes a boot task storage medium that can only be accessed by one processor at a time. A boot process of the system has a first stage and a second stage. During the first stage, the first processor fetches and executes boot tasks without assistance from the second processor. During the second stage, boot task execution performed by first processor overlaps with at least one boot task fetch performed by the second processor.

主权项

1. A system, comprising:
a first processor; a second processor configured to fetch but not to execute boot driver routines; and a boot task storage medium that can only be accessed by one of the first and second processors at a time, wherein a boot process of the system has a first stage and a second stage, during the first stage, the first processor fetches and executes the boot driver routines without assistance from the second processor, during the second stage, boot driver routine execution performed by the first processor overlaps with at least one boot driver routine fetch performed by the second processor, wherein the overlap is enabled by execution of a multi-processor initiation driver stored by the boot task storage medium and executed by the first processor.
