Can you tell me what NIOS processor is implemented

I figured that would be easier, however I do not have access to the sopc builder and need to justify the speed of my code to people that do. I understand some sequences flush the pipeline and will slow the code. I was expecting to have a 340 DMIPS processor to work with, however if my assumptions are right this implementation is a economy processor running at 37% of max frequency resulting in approximately 18 DMIPS. I was hoping I could get a confirmation or someone could point me to some documentation that defines "tiny".
