| Abstract: |
| This paper introduces the development technology of driver which implements data transfer in the mode of DMA, with AMCC S5933 control chip as an example.A completely new and flexible method is introduced to implement data transfer in the mode of DMA by means of distribution routine to control DMA access. It breaks through the routine of ReadFile and WriteFile used to implement DMA, which makes it easier for a program to be understood, and more flexible to realize and control access operation. |
