If you wanted to burst the data to be a little more efficient, you could DMA the data over. Or, I THINK if you have a data cache, you could move data as pointers and that might burst (i.e. don't use the IOWR/RD macros that bypass the cache), but I'm not sure, I've never done that - just read about it on this forum before. If a few wasted clock cycles don't matter, then you could just do a bunch of IORD/WR ops.

I'm guessing you're using Quartus Web Edition? It doesn't support parallel compilation.
