DMA

Hello, I want to make a stream from a PIO to the SDRAM. Knowing that the values on the PIO changes every 1/27Mhz, how can the DMA "know" when the data have been changed? http://forum.niosforum....

Kero,

I was reading your reply. Does crossing clock domains slow down the throughput that much? I am going to make a post on thsi, but, can I sustain streaming at 50 Mhz( SOPC domain) to LCD controller at 35 Mhz?
