Filed:

Dec 13, 2006

Appl. No.:

11/610502

Inventors:

William Tsu - San Jose CA, US
Ashish Kaul - Santa Clara CA, US

Assignee:

NVIDIA Corporation - Santa Clara CA

International Classification:

G06F 13/36

US Classification:

710311, 713320

Abstract:

Circuits, methods, and apparatus that provide transactions to wake an external device from a low-power state before a data transfer. This prevents an interruption that would be caused if the external device exited the low-power state during the data transfer. One example monitors a need for data by a first device. At a predetermined time before data is needed, the first device sends a transaction to a second device. The transaction is intended to wake the second device from a low-power state. If the first device has information to indicate that the second device is not in a low-power state, this transaction can be skipped. The first device then requests data. Later transactions to the second device do not result in the second device exiting the low-power state and therefore do not interrupt or cause delays in the data transfer.

International Classification:

G06F 13/36

US Classification:

710310000

Abstract:

Multiple data transfer requests can be merged and transmitted as a single packet on a packetized bus such as a PCI Express (PCI-E) bus. In one embodiment, requests are combined if they are directed to contiguous address ranges in the same target device. An opportunistic merging procedure is advantageously used that merges a first request with a later request if the first request and the later request are mergeable and are received within a holdoff period that is dynamically determined based on a level of bus activity; otherwise, requests can be transmitted without merging.

International Classification:

G06F 12/00

US Classification:

711207

Abstract:

Circuits, methods, and apparatus that reduce or eliminate system memory accesses to retrieve address translation information. In one example, these accesses are reduced or eliminated by pre-populating a graphics TLB with entries that are used to translate virtual addresses used by a GPU to physical addresses used by a system memory. Translation information is maintained by locking or restricting entries in the graphics TLB that are needed for display access. This may be done by limiting access to certain locations in the graphics TLB, by storing flags or other identifying information in the graphics TLB, or by other appropriate methods. In another example, memory space is allocated by a system BIOS for a GPU, which stores a base address and address range. Virtual addresses in the address range are translated by adding them to the base address.

International Classification:

G06F 21/62
G06F 17/24
G06F 3/0484
G16H 10/60

Abstract:

Examples disclosed herein include a method for securely collecting and managing document data is disclosed. First handwriting data is received from a first user device. Responsive to receiving the first handwriting data, an additional handwriting data security process is initiated. After initiating the additional handwriting data security process, additional handwriting data is received from a second user device. Based on the additional handwriting data security process, the first handwriting data is accepted or rejected. After accepting the first handwriting data, a document is generated with the first handwriting data and the additional handwriting data being applied to the document.

International Classification:

G06K 9/00
G06Q 50/18

Abstract:

A method for enhancing efficiency of a computerized electronic signature system by facilitating collection of signatures from multiple signatories is described. The method may initially involve verifying an identity of a first signatory by receiving data from the first signatory electronically, providing a document to the first signatory, receiving a first electronic signature on the document from the first signatory, and receiving a selection from the first signatory of a second signatory to sign the document as a witness. The method may then involve verifying an identity of the second signatory by receiving data from the second signatory electronically, providing the document to the second signatory, receiving a second electronic signature from the second signatory, providing a completed document, including the first signature and the second signature, and notifying the first signatory and the second signatory that the completed document is completed.
