The AdEXP1562 is a PCI Express-compatible StarFabric bridge board. This board enhances the speed of data transfer between the computer and the node that is StarFabric-linked. It is effective if no DMA controller is embedded in the computer.
StarGen® device driver and utility program are capable of running directly by virtue of the StarFabric bridge chip that is connected to PCI Express via the transparent PCI/PCI bridge.
Equipped with the DMA controller, which is included in the transparent relay PCI/PCI bridge, capable of high-speed data transfer downward. (in direction of data transmission to the StarFabric network).
Separate buses are assigned on both sides of the DMA controller and this permits simultaneous processing of data reading from PCI Express and writing to StarFabric. Moreover these separated buses allow to performs high-speed DMA data transfer.
