Overview

Medha’s A664 End System is an FPGA-based solution implemented in a compact 3U VPX form factor. Compliant with ARINC 664 Part 7, it provides secure and reliable communication with deterministic Quality of Service (QoS), ensuring bounded latency and jitter.

Designed for network communication in safety-critical systems, the A664 End System incorporates onboard integrity checking, redundancy and flow control. A PCIe interface enables communication with the host system.

The hardware and firmware are developed in-house and can be customised to suit specific form-factor and host-interface requirements. The solution is also available as an IP core.
