ARINC 429 IP Core with Axi-lite interface

Description

The ARINC 429 Multi-Channel IP Core is a high-performance VHDL-based communication solution designed for AMD FPGA avionics applications requiring flexible, scalable, and fully configurable ARINC 429 interfaces.

The IP integrates:

• 8 independent ARINC 429 receiver channels
• 8 independent ARINC 429 transmitter channels
• a full AXI4-Lite control and data interface

Built for modern FPGA architectures, the core enables seamless integration into embedded aerospace systems, mission computers, communication gateways, and avionics test platforms.

Main Features

• Fully written in VHDL
• 8 RX + 8 TX ARINC 429 interfaces
• AXI-Lite register interface for configuration and data access
• Independent configuration of each channel
• Per-channel speed selection
• Individual enable/disable control
• Integrated error detection and status monitoring
• Modular and scalable architecture
• FPGA-friendly implementation
• Easy integration into SoC and embedded designs

Advanced Control Capabilities

Each ARINC channel can be configured independently through AXI-Lite registers, allowing software to dynamically manage:

• transmission/reception control,
• bus speed configuration,
• error handling,
• status monitoring,
• and communication management.

This architecture provides maximum flexibility for complex avionics systems with multiple ARINC endpoints.

Error Management

The IP includes dedicated monitoring and error management mechanisms to improve system reliability and simplify debugging:

• parity error detection,
• invalid word detection,
• transmission status flags,
• receiver monitoring,
• and configurable status registers.

Applications

Typical applications include:

• aerospace FPGA systems,
• avionics communication modules,
• ARINC gateways,
• mission computers,
• hardware-in-the-loop platforms,
• embedded test systems,
• and protocol analysis equipment.

Designed with scalability and maintainability in mind, the IP is suitable for both prototyping and production-grade aerospace developments.
