US Patent:

20070168590, Jul 19, 2007

Filed:

Nov 15, 2006

Appl. No.:

11/560071

Inventors:

International Classification:

G06F 13/38

US Classification:

710 71

Abstract:

System and method for performing distributed input/output (I/O). A distributed I/O device (the device) coupled to a controller may read data from a serial port, may determine if the data are framed by time, and if so, may handle the data according to a time-based protocol. If the data are not framed by time, the device may determine if the data are framed by delimiters, and if so, may determine an appropriate delimiter-based protocol for the data from a plurality of delimiter-based protocols, and handle the data according to the appropriate delimiter-based protocol. This process may be repeated in an iterative manner to read a stream of data from the serial port. The device may include or be coupled to one or more I/O modules (e.g., for DAQ, motion control, etc.), which themselves may be coupled to a unit under test or other external device or phenomenon via additional devices.

Abstract:

Various embodiments of a system and method for performing a measurement application are described herein. The system may include a host computer having a processor, and a measurement device having a programmable hardware element. The programmable hardware element may be configured to perform a loop to acquire measurement data from a physical system. The host computer may be configured to perform another loop to read the measurement data from the programmable hardware element and use the measurement data in a measurement and control algorithm. The host computer may be further configured to perform a synchronization algorithm to keep the measurement data acquisition loop performed by the programmable hardware element synchronized with the measurement and control loop performed by the host computer.
