Abstract

The integrated modular avionics (IMA) system has quite a number of line repalceable moduels (LRMs) in a cabinet. The LRM performs functions like line replaceable units (LRUs) in federated architecture. The video processing module (VPM) acts as a video bus bridge and gateway of ARINC 818 avionics digital video bus (ADVB). The VPM is a LRM in IMA core system. The ARINC 818 video interface and protocol standard was developed for high-bandwidth, low-latency and uncompressed digital video transmission. FPGAs of the VPM include video processing function such as ARINC 818 to DVI, DVI to ARINC 818 convertor, video decoder and overlay. In this paper we explain how to implement VPM's Hardware. Also we show the verification results about VPM functions and IP core performance.

모듈통합형 항공전자시스템은 연방형의 LRU (line replaceable unit)의 기능을 하나의 LRM (line replaceable module)에서 제공하고, 하나의 cabinet에 여러 개의 LRM을 탑재한다. IMA core 시스템의 VPM (video processing module)은 LRM으로써 ARINC 818 ADVB (avionics digital video bus)의 bridge 및 gateway 역할을 한다. ARINC 818은 광 대역폭, 적은 지연시간, 비 압축 디지털영상 전송을 위해 개발된 규격이다. VPM의 FPGA IP core는 ARINC 818 to DVI 또는 DVI to ARINC 818 처리와 video decoder, overlay 기능을 가진다. 본 논문에서는 VPM 하드웨어 구현에 대해 다루고, VPM 기능과 IP core 성능 검증 결과를 보인다.
