Hi, Does anyone perform Dhrystone 2.1 benchmark with a 405GP ? I've tried and i got : 172 Mips (Walnut board @200Mhz, HHL2.0). I've also tried to run the same benchmark with the same board with the basic_os and the ibm "highcppc" compiler and i found 237 Mips (the 405GP specifications give 282 Mips @200Mhz, they told me that was obtained with a Diab compiler). Is there any reason my result (172 Mips) is so far from ~240 Mips. (i've used : ppc_405-gcc -DUNIX -DROPT -O2 -fomit-frame-pointer dhry21a.c dhry21b.c timers_b.c -o dhry21 )
