本文解决了该系列09篇中的一个显著bug，同时也是对多核写作图像处理OMP示例的扩充。本系列10篇：CCS+C6678LE开发记录10:(图像)数据处理与传输框架本文根据...mcsdk_2_01_02_06demosimage_processingopenmpc6678l示例进行修改。原示例是DSP通过HTTP网页服务和PC连接传输数据，修改之后进行了“瘦身”，移除所有webpages，改为UDP数据包方式传送数据。关于UDP传输可以参考这篇文章CCS+C6678LE开发记录03:常规入门HeloWorld 综合之后完成的项目已经上传到GitHub仓库（因为一些原因，暂不公开，如有需要请私信） DSP端(CCSv6) NA PC端(VS2013) NA
测试结果如下
首先连接EVM等待Network初始化完成 ... PC端发送数据

发布了动态图，只能发几张独立的

DSP端发回处理结果数据

原始图片比较大，网络传输消耗了大部分时间。以下是CCS调试输出
