This is a simple memory speed tester for Delfina DSP. Just run it and see
the results.. For reference, here are the results for A4000 with 40MHz Warp
Engine.

With no DSP processing active: 

32bit Delfina->Amiga: 2226835 bytes/sec
32bit Amiga->Delfina: 2185448 bytes/sec
24bit Delfina->Amiga: 1709417 bytes/sec
24bit Amiga->Delfina: 1660091 bytes/sec
16bit Delfina->Amiga: 2268516 bytes/sec
16bit Amiga->Delfina: 1997447 bytes/sec
 8bit Delfina->Amiga: 1148537 bytes/sec
 8bit Amiga->Delfina: 1023588 bytes/sec


DelFX running at the same time:

32bit Delfina->Amiga: 2134770 bytes/sec
32bit Amiga->Delfina: 2068241 bytes/sec
24bit Delfina->Amiga: 1661097 bytes/sec
24bit Amiga->Delfina: 1621695 bytes/sec
16bit Delfina->Amiga: 2216279 bytes/sec
16bit Amiga->Delfina: 1886247 bytes/sec
 8bit Delfina->Amiga: 1084813 bytes/sec
 8bit Amiga->Delfina: 981591 bytes/sec


DelFX has a huge audio interrupt that will suck almost all CPU time in
Delfina. As you can see, this has almost no effect in memory transfer
speeds.

Tell me if you get higher values! A real Zorro-II machine like A2000 could
perform better, on Zorro-III some cycles are lost to bus synchronising.
