Benchmark - how to raise clock frequency?

Hello, currently I'm doing some benchmark evaluation (dhrystone) on my Cyclone III Evalboard "BeMicro". I'm using the Nios II/e for the simplest option. The benchmark tells me 0,124 MIPS/MHz,...

Harry_DC,

What do you really need? A higher FPGA frequency or more computation power? If you go for the later I suggest that you don't use the /e version of the NIOS CPU. This e means economic in terms of ressource usage. If you need CPU power than you should use /f. Furthermore, it's neccessary to check the externam SRAM interface. If you use the external SRAM and increase the system clock then it might be neccessary to increase the number of wait states for the RAM.

Hope that helps,

Harald
