Description: PCI驱动编程实例，通过PCI可实施操作：
2、通过DMA方式往SDRAM写数据的步骤：
(1) 往OMB1写传输数据次数
(2) 往OMB2写所要访问的SDRAM地址
(3) 往FIFO写2
3、通过DMA方式从SDRAM读数据的步骤：
(1) 往OMB1写传输数据次数
(2) 往OMB2写所要访问的SDRAM地址
(3) 往FIFO写3
-PCI-driven programming examples, can be implemented through the PCI operation : 2, DMA SDRAM write data to the steps : (a) to transfer data OMB1 write the number (2) to OMB2 was to be visited SDRAM Address (3) to FIFO write 2 3 through DMA side SDRAM-time data from the steps : (a) to transfer data OMB1 write the number (2) to OMB2 was to be visited SDRAM Address (3) to write FIFO 3
