BeMicro SDK - Nios II/f - Cyclone IV - Performance - dhrystone

Thanks dsl

Will be using an operating system, can't use linux so will be probably use ucosII.

For our application the Ethernet input could be upto 80% loaded and we need to store some of this data (upd / tcp + commercial grade web server) The application has a lot of other thinks to do as well.

"i'm not sure exactly what the dhrystone benchmark does...

given the effect of cache sizes, you really need a test that is much the same as the code you need to run - not some random benchmark."

Agree, however no code exists... This is just to get warm feeling that the processor has enough power (anything with no caches will be too slow).

The application will be fairly big and multi tasking (can't fit into internal sram block), likely to run from DDR ram...caches are there to over come slow performance of DDR ram

Have not got that warm feeling yet, will attempt to try some performances tests using ucosII and InterNiche stack
