Using the ps3fb device, your application writes to a main-memory (offscreen) buffer.
使用ps 3 fb设备,您的应用程序会写入主存(offscreen)缓冲区。
For example, to get input, we may need to specify the file or device to use as the source, and the address and length of the memory buffer into which the input should be read.
例如,为了获取输入,我们可能需要指定文件或设备作为信息来源,并且要把地址和内存缓冲区的长度放到输入读取的位置。
Then the driver commands the device to do its job (by manipulating its registers) and the device transfers output data directly to the allocated buffer in the memory.
之后,驾驶员命令设备来完成其工作(通过操纵其寄存器)和直接在设备传送输出数据在存储器中分配的缓冲区。
The ECC controller transmits the data to a direct memory access (DMA) buffer for transfer to the host device, and to an ECC block for error detection and correction of the data.
ECC控制器将数据发送给用于将数 据传送到主机装置的直接存储器存取(DMA)缓冲器以及用于对数据进行错误检测和纠错的ECC块。
