While DMA transfers are an excellent way of moving bulk data between the SPE and the PPE, another simpler method for smaller transfers which I will briefly discuss is mailboxes.
虽然dma传输是一个很好的在SPE和PPE传输大量数据的方法，但对于小型的数据传输来说，还有另一种更为简单的方法，即邮箱，在这里简单介绍一下。
DMA transfers are almost always done by the SPEs rather than by the PPE because they can handle much more data and many more active DMA operations than the PPE.
dma传输基本上总由spe而非ppe完成，原因是SPE较P pe而言可以处理更多的数据和更多的当前dma操作。
The main function of DMA engine is to handle the receive and transmit data and descriptor transfers between the host memory and the NIC.
