Abstract: An IO controller device and method for controlling data flow, the method including determining a desired configuration for the IO controller, reprogramming the IO controller to allow for processing of one or more descriptor lists, modifying the configuration of the IO controller to reflect the addition or deletion of one or more virtual controllers, re-enumerating the IO controller, and processing a descriptor list for each of the IO controller and the one or more virtual controllers. The integrated circuit device for use as an IO controller includes a system bus interface, a programmable list processor and a port router. The integrated circuit device is adapted for reconfiguration to add or delete one or more virtual controllers. The virtual controllers provide substantially the full bandwidth supported by the integrated circuit device.

Abstract: In an optical material formed of strips of laminated methods, through channels or "trenches" are produced in at least one of the lamination materials in a manner that the material will then consist of "stiff islands" interspersed with flexible regions created by the properly created through channels. The trenching alows a strip to become piece-wise alignable, and also makes it flexible enough to bond it in alignment in a laminate, yet continuous enough to be handled as one sheet for initial placement. "Chain-like" capability can be provided by making the sheet into a form resembling a jig-saw puzzle where the chances of the individual pieces slipping apart is reduced using narrow, slanted trenches. Alternatively, "springy" flexibility can be provided by forming relatively long, thin, bent strips of material that support the islands of continuous sheet. The islands are thus allowed to move two dimensionally relative to each other.
