摘要
航电系统中往往需要多种视频格式,每种视频格式都有不同的帧速率、分辨率、像素密度、帧/场格式。FC-AV协议为满足这种需求,定义了不同的视频格式在光纤通道上统一的映射标准。为了满足新一代航电系统数字视频信号的高速传输需求,并突破国外技术封锁,实现航空电子系统自主设计、核心技术自主保障,必须自主设计实现FC-AV协议处理SoC。以SoC芯片的设计、验证流程及方法为指导,重点论述了FC-AV协议处理SoC的设计和软硬件协同验证。目前,FC-AV协议处理SoC已经流片,对样片进行了性能测试和系统验证。结果表明,FC-AV协议处理SoC完全满足航电系统对视频在FC网络高速传输的功能和性能需求。
Avionic system currently utilizes many different video formats. Video formats is different in their frame rates,resolution,pixel density,and field / frame mode. In order to meet these requirements,FC- AV defines a standard for video formats mapping to fibre channel. For meeting the high- speed transmission requirement for digital video signal of next- generation avionics system,breaking out the technology blockade abroad,implementation of the self- design of avionics system and the autonomous logistics of core technology,a FC- AV protocol processing SoC must be designed and implemented. Taking SoC design / verification flowand method as the guidance,it introduces the design and hardware / software co- verification for FC- AV protocol process SoC in this paper. The result of tape- out and system level test demonstrate that the FC- AV protocol process SoC can meet the performance and function requirement of avionics system for video data high- speed transmission on FC network.
