- High-performance FPGA-only design – no firmware
- Low host CPU load through FIFOs
- Optional bidirectional discrete I/O and IRIG-B
- Optional galvanic isolation for the ARINC 429 and discrete I/O user interface
- Sophisticated error injection & detection features, programmable bus load
- Driver & API support for Windows 2k/XP/Vista and Linux
Overview
TechSAT's A429-PMC-cPCI is a powerful, multichannel ARINC 429 interface implemented on a PMC (PCI Mezzanine Card) form factor module form factor module mounted on a standard PMC-to-PCI carrier. It has been specially designed to comply with high-performance test and simulation requirements where the ARINC 429 bus is used.
The A429-PMC-cPCI features a fully parallel hardware design with strictly independent Tx-/Rx-channel state-machines. The dual global FIFO host interface allows for extremely simplifi ed and accelerated board access. The fully autonomous hardware implemented Tx-scheduler and the Rx-FIFO handler relieve any host platform from realtime tasks. Receive time stamping and error detection are also implemented in hardware.
The A429-PMC-cPCI is equipped with comprehensive test features such as error injection/detection. Galvanic isolation, bidirectional discrete I/O lines, IRIG-B input and conformal coating are available as an option.
A429-PMC-cPCI is supported by TechSAT’s ADS2 (Avionics Development System - 2nd Generation) which is used as a software platform in numerous test- and integration environments. In addition the A429-PMC-cPCI is based on the unifi ed TechSAT Software Environment Interface architecture that can be found on various other TechSAT interface products. The A429-PMC-cPCI comes with driver and interface library for Microsoft Windows 2k/XP/Vista and Linux.
