In at least one embodiment there is provided a method for managing bulk capacitance of a power supply system. The method includes precharging first and second bulk capacitors of the power supply system to approximately a first output voltage level and a second output voltage level, respectively; receiving a first command signal to generate, by the power supply, the first output voltage level; coupling the first bulk capacitance to load circuitry coupled to the power supply; receiving a second command signal to generate, by the power supply, the second output voltage level; and coupling the second bulk capacitance to the load circuitry coupled to the power supply.

A system employs a white list of authorized transactions to control access to system registers. In an embodiment, the white list is loaded into filter registers during system boot. Routing logic monitors a logical interconnect fabric of the system for register access requests. The routing logic parses source, destination information from a request to index the white list. If the white list includes an entry corresponding to the processing entity indicated in the source information and the register indicated in the destination information, the routing logic will permit the requested access.
