Overview

The TechSAT AFDX-PMC is a powerful AFDX®/ARINC 664 interface implemented on a PMC (PCI Mezzanine Card) form factor module. It implements the AFDX® protocol stack in onboard firmware and FPGA logic thereby off-loading the host. By changing the FPGA logic and firmware versions, the module can be configured to be compliant with either the Airbus or Boeing AFDX® protocol stack.

AFDX-PMC is equipped with two full duplex AFDX networks that can be operated in either independent or dual-redundant mode.The AFDX-PMC connector interface can be either twisted paircopper or bi-directional fiber-optic Small Form-Factor Pluggable(SFP).

In addition to the AFDX® protocol stack, the AFDX-PMC also implements comprehensive test features such as error injection/detection, filtering, triggering and discrete I/O lines. Optimized for performance, the AFDX-PMC is ideal for applications such as AFDX® ES (End System) testing and validation, ES simulation and ARINC 615A data loading via AFDX®.

Software Support

AFDX-PMC is shipped with a C-API and drivers for either Windows, Linux or VxWorks. In addition, several sofware tools for test, simulation and dataloading purposes are available on request. For test puposes, TechSAT has developed a powerful AFDX® analyzer as well as an AFDX® ES test and validation tool.

Furthermore, TechSAT has developed several AFDX® based protocol simulations for the Airbus A380 and A400M as well as for the Boeing 787. Finally, AFDX-PMC also supports the TechSAT tool suite for dataloading over ARINC 615A.

Architecture

As depicted in the block diagram, the host communicates with AFDX-PMC via a dedicated driver. The driver uses I2O and DMA for fast data transfers between the host and AFDX-PMC. The on-board CPU runs the AFDX® protocol stack as well as controlling the FPGA which offloads the CPU by handling Tx scheduling and error injection/detection.
