I do have implementation of two bcrypt cores which works in simulation. However, on ZedBoard one core works fine while the other one produces incorrect result. I haven't managed to figure out where is the problem yet, especially because both cores use the same logic. Unfortunately, I encountered clock problems again. PlanAhead reports maximum implemented frequency to be 84 MHz. But changing it had no influence on outcome - first core works on 100 MHz clock while incorrect result from the other core is the same for different clock frequencies. I tried 83 MHz clock but it had same performance as 100 MHz clock which is the same problem as earlier. I'm using 50 MHz clock at the moment and I'll try to get other core working on that frequency. When I succeed in that, I'll experiment with higher frequencies. Katja Content of type "text/html" skipped
