Speed Measurement of A1200 Cycle Exact

One day would be possible to measure the correct timing of a A1200 in WinUAE with programs like SysInfo or AIBB?

Is not possible to measure the speed of emulators perfectly, but would exist a kludge to do it?

I am just curious.

For me, WinUAE is like an AMIGA, only better. The only problem is that I cant touch it, like the real hardware.

Why isnt it possible ? A1200 quickstart, insert aibb floppy and ya good to go. Aibb even has a default A1200 comprison built in to compare.

Currently in 68020 CE mode only bus cycles and cache memory is emulated (more or less) cycle exactly. Which is usually enough for most programs, even games and demos, at least as long as there is no fast ram.

Internal instruction execution is currently mostly instant. Problem is 68020 being too advanced compared to simple 68000, bus cycles and instruction exection can happen simultaneously which makes emulation much more complex and time consuming. Maybe someday..
