Honored ContributorIf you are worried about how long NIOS instructions take, be aware that NIOS is a very slow processor. The free one is staggeringly slow and inefficent. If this is a concern, use one of the SoC chips with built in ARM processor or write your algorithm in Verilog or VHDL. Almost any external micro will be faster than NIOS as well.
