Latest Patents
One of her latest patents is titled "Dual addressing arrangement for a communications interface architecture." This invention features a complex address pointer within entries of a communication queue, which is utilized by a port driver and a port adapter when exchanging information in a host computer. The complex address pointer consists of both a virtual address portion and a physical address portion. The port driver employs the virtual address portion to determine the location of entry structures, while the port adapter uses the physical address portion to locate these structures in the host memory. The arrangement and interpretation of the address portions depend on the direction of information flow, whether it is messages being passed from the port driver to the port adapter or responses flowing back in the opposite direction.
Another significant patent is "Queue apparatus and mechanics for a communications interface architecture." This invention describes a communication interface between a port driver and a port adapter of a host computer, which includes a singly-linked queue residing in the host memory. The queue comprises a header element and a stopper element, with message entries linked in between. Each message entry contains a carrier that holds a forward link pointer to the next entry in the queue, along with message-specific control information. The stopper element identifies the end of the queue and is distinguishable from a message entry by a valid indicator. This design allows the port driver and port adapter to concurrently insert and remove message entries in a reliable manner without requiring external synchronization.
