Parallelizing Boot Operations

摘要

The present disclosure describes apparatuses and techniques for parallelizing boot operations. In some aspects, an operation transferring a boot image from a non-volatile memory to a volatile memory is initiated prior to completion an operation validating another boot image previously-transferred into the volatile memory. This can be effective to enable transfer operations and validation operations of boot images to be performed in parallel. By so doing, delays between the transfer and validation operations can be minimized thereby reducing device boot times.

主权项

1. A method comprising:
initiating, via a direct memory access (DMA) controller, a first transfer operation transferring a first boot image from a first memory into a second memory; initiating, after completion of the first transfer operation, a validation operation of the first boot image in the first memory effective to verify that the first boot image is secure; and initiating, via the DMA controller and prior to completion of the validation operation, a second transfer operation transferring a second boot image from the first memory into the second memory.
