使用HI_MPI_VPSS_GetChnFrame获取yuv图像,然后将物理地址通过HI_MPI_SYS_MmapCache映射到虚地址进行调用。 我们需要缓存图像一定的时间,目前遇到一个问题:在其他线程调用这个虚地址会出现图像变化的问题,比如我先将图片保存到sd卡,然后sleep一段时间,再保存这个地址的图像到sd卡,通过查看y发现不是同一个图像。 这是...

Mmap是一种处理大型文件的有效方法,就好像它只是一个字节数组一样。我正在通过Infiniband与MPI一起工作,它支持进程之间的RDMA网络操作。每个MPI进程都有一个非常大的文件可与其他进程共享。每个MPI进程可以在每个大文件上创建mmap区域并与其他进程共享吗?我希望允许每个进程读取任何进程的任何文件,就好像它通过RDMA (MPI...
