Ah yes I found the Firebee results. And the test code is indeed Coldfire "native/clean" Coldfire 68080 Milan-68040 CPU_BitShift = 265 198 12 CPU_RawPower = 268 200 24 CPU_MEMOREAD = 83 534 34 CPU_MEMOWRITE = 47 663 21 ----------------------------------------- pretty interesting |
Results for firebee are quite old, I'm going to check if they do some progress since, nobody was able to understand why memory access was so low while processor speed is quite fast if run in cache, it was the same when I was using coldfire evaluation board from freescale, perhaps some wrong cache management. On several 68060 systems results could change a lot with configuration, I know a lot of that have used Kronos on CT60 just to fix the configuration up they was able to acheive reference results!

Coldfire 68080 Milan-68040 CT60/100 CPU_BitShift = 265 198 12 199 CPU_RawPower = 268 200 24 199 CPU_MEMOREAD = 83 534 34 101 CPU_MEMOWRITE = 47 663 21 101 ----------------------------------------- Bitshift - Rawpower test are directly link to frequency you have test on 100Mhz FPGA??? or there is something wrong in Emutos 200 hz Timer? Memoread-write is quite incredible you have optimized for Kronos?!!! Incredible results, you are incredible! In some month so many improvement! Very Very nice
