Byteflight is an automotive databus created by BMW and partners Motorola, Elmos Semiconductor and Infineon to address the need for a modernized safety-critical, fault tolerant means of electronic communication between automotive components.
As a predecessor to FlexRay, byteflight uses a hybrid synchronous/asynchronous TDMA based means of data transfer to circumvent deficiencies associated with pure event-triggered databuses.
Eclipse 500 jet aeroplanes use Byteflight to connect the avionics displays.
[1] In Byteflight terminology, a data frame is called a telegraph.
The telegraph ends with a 15 bit CRC value encoded in two bytes leaving the LSB unused.
