Abstract
Smart bridge and use. The smart bridge includes a functional unit, memory, and a switch for routing data between a host and multiple devices using a routing table. The bridge stores a forwarding address range (FAR) as a bridge representation of hardware memory resources required by the devices. The FAR is an integer multiple of a first specified minimum size and is aligned with the first specified minimum size. The bridge representation is converted to an endpoint representation that includes multiple virtual memory resources based on a starting address of the FAR. Each virtual memory resource has a respective sub-address range with a size that is a power of 2 multiple of a second specified minimum size, which is less than the first specified minimum size, and is aligned accordingly. The endpoint representation is usable by the switch or the host to allocate the virtual memory resources to the devices.
