摘要
本文针对现今高速数字图像信号的复杂算法实时处理要求以及系统实时升级问题, 设计一种基于 FPGA的 SOPC高速图像实时处理系统平台, 移植可定制高效操作系统 Xilkernel, 并采用多线程编程、软件仿真以及在线实时调试方法, 成功地实现了高速系统实时处理功能。 FPGA操作可并行执行及硬件反应时间精确到纳秒 (ns)级, 因而该系统实时处理性能相对于其它处理平台有明显的优势, 同时也满足了在不需更改硬件架构情况下实现系统的实时更新。
Abstract
A high-speed real-time image processing system based on System on a Programmable Chip (SOPC) of Field Programmable Gate Array (FPGA) was designed against the real-time requirements of complex algorithms for high-speed digital image signal and the existing problems that the system was updated in real time. The customized and efficient operating system Xilkernel was transplanted. And the methods of multi-thread programming, software simulation and real-time debugging online were applied. The real-time processing function of high-speed system has been achieved successfully. The operation of FPGA could be performed in parallel and the responsive time of its hardware could be accurate to nanosecond (ns) level. So the real-time processing properties of the system have more advantages over other processing platforms, and the real-time updates of the system without changing the hardware circuit have also been implemented.
