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。
Device drivers use these routines to request various types of data transfers (control, interrupt, bulk, or isochronous).
设备驱动程序使用这些例程来请求各种类型的数据传输(control、interrupt、bulk或isochronous)。
Bulk transfers: These are data packets in relatively large quantities.
批量传输：这些是数量相对大的数据包。
