7849210, Dec 7, 2010

Filed:

Dec 22, 2008

Appl. No.:

12/341438

Inventors:

Andrew B. Moch - Austin TX, US
Aaron T. Rossetto - Austin TX, US
Brent C. Schwan - Austin TX, US

Assignee:

National Instruments Corporation - Austin TX

International Classification:

G06F 15/16

US Classification:

709236, 709229, 709235, 370235, 370252

Abstract:

A mechanism for managing packetized data transfers in a system including a transmitting and a receiving device. The transmitting device may transmit data to the receiving device in a plurality of packets, each packet a predetermined number of data bytes wide. The transmitting device may include a transfer count unit to maintain a data transfer count based on a number of transmitted data bytes. The receiving device may program the transmitting device with a transfer count mark, which may be a number that corresponds to a specific count of the data transfer count. The transmitting device may calculate a difference between the data transfer count and the transfer count mark. If the difference between the transfer count and the transfer count mark is less than the predetermined number, the transmitting device may transmit a short data packet having less than the predetermined number of data bytes to the receiving device.

Abstract:

Asynchronous event-based start of input/output operations is implemented in a distributed system. Within the distributed system, each master device—of a plurality of master devices coupled to a respective plurality of slave devices via an internal network—may implement one or more timed-functions configured to control timing of physical input operations and/or physical output operations for the respective plurality of slave devices, and streams between the master device and the respective plurality of slave devices. A subset of the slave devices may be further interconnected via a shared signal-based bus, which may be used to propagate an asynchronous event that may be used to start at least one of the one or more timed functions implemented on a master device coupled to at least one slave device of the subset of slave devices. The asynchronous event may be generated by one of the slave devices.
