Publication number: 20060184711Abstract: An apparatus and method are provided that enable I/O devices to be shared among multiple operating system domains. The apparatus has a first plurality of I/O ports, a second I/O port, and core logic. The first plurality of I/O ports is coupled to a plurality of operating system domains (OSDs) through a load-store fabric, each routing transactions between the plurality of OSDs and the switching apparatus. The second I/O port is coupled to a first shared input/output endpoint. The first shared input/output endpoint requests/completes the transactions for each of the plurality of OSDs. The core logic is coupled to the first plurality of I/O ports and the second I/O port. The core logic routes the transactions between the first plurality of I/O ports and the second I/O port. The core logic designates a corresponding one of the plurality of OSDs according to a variant of a protocol, where the protocol provides for routing of the transactions only for a single OSD.Type: ApplicationFiled: April 1, 2006Publication date: August 17, 2006Applicant: NEXTIO Inc.Inventors: Christopher Pettey, Asif Khan, Annette Pagan, Richard Pekkala, Robert Utley

Publication number: 20050086416Abstract: A processor includes controller circuitry operative to control the storage of a plurality of separate linked list data structures for protocol data units received by the processor. The linked list data structures are stored in memory circuitry associated with the processor, and the memory circuitry is arranged in a plurality of banks. The plurality of banks are configured to store respective ones of the plurality of separate linked list data structures, such that each of the plurality of banks stores a corresponding one of the plurality of separate linked list data structures. The linked list data structures are accessed in an alternating manner that reduces the likelihood of access conflicts between the banks. The processor may be configured as a network processor integrated circuit to provide an interface between a network and a switch fabric in a router or switch.Type: ApplicationFiled: September 30, 2003Publication date: April 21, 2005Inventor: Robert Utley

Publication number: 20050071528Abstract: A processor includes a plurality of input ports, memory circuitry for storing data blocks associated with protocol data units (PDUs) and received by the processor at the input ports, and controller circuitry coupled to the memory circuitry. The controller circuitry is operative to discard certain ones of the data blocks received at the input ports in an oversubscription condition in which the received data blocks exceed a designated capacity of the processor. A discarded data block indicator is generated for a given one of the input ports if a data block received at the given input port for a particular PDU is discarded. One or more additional data blocks received at the given input port for the particular PDU are discarded based at least in part on the discarded data block indicator. The oversubscription condition may thereby be overcome in a manner which advantageously minimizes the number of received PDUs that are corrupted through discarded data blocks.Type: ApplicationFiled: September 30, 2003Publication date: March 31, 2005Inventor: Robert Utley

Publication number: 20050025154Abstract: A processor includes controller circuitry configurable to determine for a given packet or other protocol data unit (PDU) received by the processor whether the given PDU is a single-cell PDU. If the given PDU is a single-cell PDU, information characterizing the given PDU is stored in first memory circuitry internal to the processor, without utilizing a linked list data structure. If the given PDU is not a single-cell PDU, information characterizing the PDU is stored in second memory circuitry external to the processor, utilizing a linked list data structure. The processor may be configured as a network processor integrated circuit to provide an interface between a network and a switch fabric in a router or switch.Type: ApplicationFiled: July 30, 2003Publication date: February 3, 2005Inventors: Robert Corley, Robert Utley

Patent number: 5420974Abstract: A multimedia document form system enables the definition, manipulation, storage and editing of a form which contains multimedia objects. Image objects and text objects can be displayed on the form in the conventional manner. Nonvisual presentation objects such as video objects and audio objects are represented by check boxes on the form. If a nonvisual object is to be associated with the form, then a mark is applied to the corresponding check box on the form. When the form is scanned-in in an optical scanner, presence of a mark in the check box prompts the operator to enter the nonvisual object. For example an audio object will be entered in digitized form and stored in association with the form. When the form is then displayed on a visual display device, the corresponding check box is highlighted to indicate to the operator the presence of a nonvisual presentation object which is stored in association with the form.Type: GrantFiled: October 15, 1992Date of Patent: May 30, 1995Assignee: International Business Machines CorporationInventors: James K.

Patent number: 5038392Abstract: In a system for capturing an image of a document having a characterizing indicium associated therewith, the invention includes the step of storing in the system a plurality of document templates. Each document template defines locations of a first type and second type information blocks on a corresponding one of a plurality of document types. The document templates are accessible by an indicium value. The invention further includes storing in the system a table relating the first type information block to first type processing parameters and a second type information block to second type processing parameters. The invention further includes the step of capturing an image of the document and storing the image in an image buffer. Then, a characterizing indicium associated with the document is recognized by the system. Thereafter, one of the plurality of document templates is accessed in response to a value of the recognized characterizing indicium associated with the document.Type: GrantFiled: February 12, 1990Date of Patent: August 6, 1991Assignee: International Business Machines CorporationInventors: James K.
