hi, I'm using the STM32f407-discovery board example of DMA_FLASH_RAM.
I've noticed by using systics for time measurements, that memcpy provides better timing than DMA.
for example.
I have 16bit array of 64 elements to send.
by memcpy the transer lasted 293systics 
by DMA 973systics 
i only activate the DMA and wait for the status to change.

Thanks for assistance !!
