AFDX Project
Description
Avionics Full-Duplex Switched Ethernet (AFDX) is Part 7 of the ARINC 664 specification.
The AFDX product is comprised of two seperate components: 1) The AFDX Device Library; and 2) The AFDX Device Driver. The AFDX Device Library is a shared object (or run-time link-able library) that provides a programic interface to the Rockwell Collins AFDX ASIC. While the AFDX Device Library can be used without the AFDX Device Driver, the inverse does not hold true (see below).
The AFDX Device Driver is a Deos user mode application that moves data between other user applications and the AFDX bus. The AFDX device driver is responsible for breaking down input packets from the AFDX bus into user-required data. Conversely, the driver builds output packets with data collected from user applications. User applications interface with the driver via the IOI and the driver uses the AFDX Library to interface with the Rockwell Collins AFDX ASIC.
