与内存流控制器(MFC)进行交互的API是由mfs头文件提供的。
The API for interacting with the memory flow controller (MFC) is provided by the MFC headers.
它们可用来向内存流控制器发出dma命令、处理SPE事件、向PPE和从PPE读写消息。
They are used for issuing DMA commands to the memory flow controller, handling SPE events, and reading and writing messages to and from the PPE.
SPE不能直接读取主存，相反地必须通过对内存流控制器(或mfc)的单元使用dma命令来在本地存储和主存之间导入和导出数据。
The SPE cannot read main memory directly, but instead must import and export data between the local store and main memory using DMA commands to a unit called the memory flow controller, or MFC.
