How to freeze NIOS2 during sensitive measurement?

Hi community, we currently design a device where we use logic in a Cyclone for very accurate measuring. Beside the logic for measuring, there is a NIOS II in the same FPGA to processing the res...

the measurement logic fires at 20 khz on its own. the nios accesses the peripheral regularly but only at 1 khz rate.[/b]

So what is creating hiccups, the accesses of NIOS to the custom peripheral or is NIOS not fast enough to process the results (FIFO overflow)?

In what kind of memory is code and data located?
