Porting PIO C-code from ARM-7 to Nios II (SE1-board) + performance issue.

Hi all,

this was a very interesting discussion for me with a lot of

interesting informationen.Thank you very much.

I am still surprised about the big performance difference, though

and was of the opinion to port the ARM-7 data transfer C-code

direct to Nios II. ( In my case, about 250Khz/16bit tranfer rate )

Now, I will redesign my project to run most of the design in pure hardware

I am having a try now with SOPC DMA Controller Core.

Regards, Reinhard
