Abstract
One embodiment of the invention provides a firmware architecture which splits firmware modules to support safe updates of specific modules as well as supporting multiple different processors. A firmware image is partitioned into several different binaries based on their update requirements and processor/platform dependence. A firmware interface table enables safe updates by enabling the option of redundant copies of specific modules as well as supporting systems with different and/or multiple processor types, mixed processors from the same family, and/or fault resilient firmware updates.
