A question about DMA speed of C6711 - Xiang Chao - Jan 16 3:40:00 2006

I am confused about the speed I can achieve. On my
board, the SDRAM can be read at 150ns with assembly
code, but with DMA, only 400ns is obtained. Why the
DMA is slower than assembly code? Could anybody give
me some suggestions?

thx

Chao Xiang
