摘要

为促进航空测绘信息获取的数字化、一体化、实时化

本文利用FPGA(Field-Programmable Gate Array

即现场可编程门阵列)并行处理的优势结合ARM处理器低功耗高性能的特点

基于ARM+FPGA的双核硬件架构实现了影像的交互与显示。该系统以Linux操作系统为软件开发平台

以ARM11嵌入式处理器为硬件核心、FPGA作为协处理器

采用FPGA片内FIFO(First Input First Output

即先进先出存储器)作为ARM处理器与FPGA之间的高速通信桥梁

针对Linux 2.6.36内核完成了对FPGA设备的驱动设计

并基于Qt图形用户界面实现了影像的实时显示。测试结果表明

ARM处理器与FPGA之间能够实现VGA(640480)图像的高速交互

帧率可达26帧/s

最大传输带宽为182 Mbps。该系统不仅体积小、功耗低、成本低

而且稳定性好、功能强

能够满足航空遥感摄影系统的实时性要求。

Abstract

To promote the integration of mapping information obtained

image interaction and display are realized based on the dual-core ARM+FPGA hardware architecture in this paper by taking full advantage of the parallel processor FPGA (Field-Programmable Gate Array) and the high-performance ARM processor.The real-time image display is realized based on Qt graphical interface and the driven design of FPGA FIFO (First Input First Output) is completed in the Linux 2.6.36 kernel which uses Linux operating system as the software platform

ARM11 as the core of embedded hardware processor and FPGA as the coprocessor.The test results show that it could achieve high speed VGA (640480) format image interaction between ARM and FPGA with the maximum frame rate of 26 fps and the maximum transmission bandwidth of 182 Mbps.This system not only has the advantages of small volume

low power consumption

low cost

but also has good performance of stability and functionality.Moreover

it could meet the real-time requirements for the aerial remote sensing system.
