DMA method for NAND flash based on PXA3xx processor
Zhang Wei-hong · Journal of Computer Applications · 2009
According to the characteristics of PXA3xx processor,a solution of DMA controller system architecture was put forward and the low level NAND flash Direct Memory Access (DMA) driver under Linux was realized. Test method was designed in JFFS2 file system layer for data read. Test results show that DMA could improve the performance of NAND flash read efficiently,and relieve NAND flash performance bottleneck.
