Abstract: Disclosed is a power isolation and backup system. When a power fail condition is detected, temporary storage is flushed to an SDRAM. After the flush, interfaces are halted, and power is removed from most of the chip except the SDRAM subsystem. The SDRAM subsystem copies data from an SDRAM to a flash memory. On the way, the data may be encrypted, and/or a data integrity signature calculated. To restore data, the SDRAM subsystem copies data from the flash memory to the SDRAM. On the way, the data being restored may be decrypted, and/or a data integrity signature checked.

Abstract: An apparatus and a computer-implemented method for processing data in a bus system component. The bus system component is configured to operate in one of an endpoint mode and a root complex mode. Responsive to configuring the bus system component to operate in endpoint mode, the data is processed through the bus system component according to an endpoint process. Responsive to configuring the bus system component to operate in root complex mode, the data is transferred through the bus system component according to a root complex mode. In an illustrative example, the bus system component is a peripheral control interconnect express component.
