Hi,

are you using Nios II/fast ?

there seems to be dependencies into your instruction: your are losing some cycles...

ld/stw should take one instruction only when they use cache memory.

maybe also you would prefer to use DMA.

what about printing a dump of assembly code; instead of C inline assembly...
