Appl. No.:

14/145636

Inventors:

- Schenectady NY, US
Michael Glynn Wise - Roanoke VA, US
Steven James Schmitt - Roanoke VA, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

H04L 1/00
H03M 13/05

Abstract:

One embodiment describes a method for real time error correction in a data transmission system that includes receiving a first communication signal on a first programmable logic device from a second programmable logic device via a first serial link, receiving a second communication signal on the first programmable logic device from the second programmable logic device via a second serial link, in which the first serial link and the second serial link are disposed in parallel with each other and are configured to communicate over a single conduit, and the first communication signal and the second communication signal are representative of identical information. The method further includes comparing the first communication signal and the second communication signal in the first programmable logic device to detect an error in data in the first communication signal, the second communication signal, or both, and when the error is detected, correcting the error in real time in the first programmable logic device based at least in part on the comparison of the first communication signal and the second communication signal.

Abstract:

One embodiment describes a fault tolerant transmission system that includes a programmable logic device. The programmable logic device includes a first serial port communicatively coupled to a first serial link, in which the first serial port receives a first transmission signal from the first serial link, and a second serial port communicatively coupled to a second serial link, in which the second serial port receives a second transmission signal from the second serial link. The first serial link and the second serial link are disposed in parallel with each other and communicate over a first single conduit, and the first communication signal and the second communication signal are representative of identical information. The programmable logic device further includes circuitry that detects a fault in the first serial link, the second serial link, or both by comparing the first communication signal and the second, and if a fault is detected, determines whether the transmission system can continue operation despite the fault.
