基于CPU+GPU的图像处理模块设计

Design of image process moudle based on CPU+GPU

伴随着机载设备的集成化和智能化越来越高,系统对图像处理的要求也与日俱增,既能在单一平台处理复杂图像视频算法和数据信息存储,又能与外部交联互通。文章介绍了一种基于CPU和GPU构架的图像处理方案,阐述了图像处理模块的组成原理和结构,并对模块内部电路设计进行了重点介绍。文章设计的图像处理模块支持综合显示界面绘制、二维/三维数字地图加速等功能,满足了机载系统图像处理高性能、高可靠、高集成的要求。

With the integration and intelligence of airborne equipment getting higher and higher, the system’s r equirements for image processing are also increasing. The system requires the ability to process complex image and video algorithms and data information storage on a single platform, and to interconnect with external cross-links. This p aper introduces an image processing scheme based on CPU and GPU architecture, which includes the image processing o f hardware part of the principle and structure, and focuses on the internal circuit design of the module. The image p rocessing module supports functions such as comprehensive display interface drawing and 2D/3D digital map a cceleration. It meets the requirements of high performance, high reliability and high integration of on-board system i mage processing.
