Hello

Thanks first for your help. But i'm pritty new in this development area, so i have some problems with your answer.

Fact is that i read some data from the avalon bus, do some small calcolations, and write on the avalon bus. This time needs more than 8ms. I can not believe this bad performance.

So what can be this delay. Or is this a regular delay?

I have a Nios /f 85Mhz. Connected my Hw with the Slave port of the NIOS would the Master be better? My Hw is running on 50Mhz.

Do i have a problem with the JTAG. I have the same speed with printf() and without. Sould a printf which is written via the JTAG to the terminal not i high delay?

I hope you can help me

sorry for my english
