先附上Freescale的IPU功能概述与使用原则:
The goal of the IPU is to provide comprehensive support for the flow of data from an image sensor and/or to a display device. This support covers all aspects of these activities:
• Connectivity to relevant devices - cameras, displays, graphics accelerators, TV encoders and decoders.
• Related image processing and manipulation: sensor image signal processing, display processing, image conversions, etc.
• Synchronization and control capabilities (to avoid tearing artifacts). This integrative approach leads to several significant advantages:
•

本文介绍了Freescale的IPU在图像传感器到显示设备数据流中的全面支持作用,包括设备连接、图像处理、同步控制等功能。IPU的优势在于减少ARM平台的参与,优化数据路径,资源共享,并通过配置支持各种应用和外部设备。同时,文章探讨了IPU在系统架构中的位置及其与其他模块的交互。
