when i say everything i mean the kitchen sink, mmu. Fpu, branch, caches and dma at least.
Hi, does anybody knows do we need extra hardware for A2000, i have "plain one" Ecs , 1Mb chip ram and Kickstart 37.299, ...
It occurred to me that if you can provide 68k and "AGA" in an FPGA, wouldn't PowerPC also be possible?
All these execution per clock comments just crack me up.If you to look at it this simplistically, a 6809 would look just as good as a 68000 in that the 6809 executes memory reads or writes in one cycle while the 68000 requires four cycles.Of course the 68000 can do this on a bus that is twice as large, so comparing an 8 bit processor (with some limited internal 16 bit capability) to a 32 bit processor (even if it addresses memory on a 16 bit bus), is perfectly silly.As to comparing a 200-300 MHz 68K equivalent (or even 68040 equivalent) to a PPC, that's completely absurd.When you have your hardware, run ANY basic benchmark for CPU performance and memory bandwidth and I'll throw you back figures from a relatively slow PPC based system.If you really think you're going to approach it, you're delusional.There was a reason Motorola halted development of the 68K.But then I guess you guys (and Gunnar) know better.Right?Look I have an A2000, and this looks tempting, but there is no real contest.If I decide to buy a Vampire for my A2000, I'm still buying an X5000.Because even a Tabor board would mop up a Vampire based computer.And an X5000 is going to be much more competent than Tabor.You guys can argue whatever you'd like, but you you can't have a separate set of facts because the truth is...well its reality.So before you sound too much like "the moon landings were fake" conspiracy nut jobs (or worse yet, people dumb enough to buy into Donald Trump), take the tinfoil cap off your head, get a cool drink of water and think this over.Its FPGA based, and not even a high end FPGA (which would cost big bucks), so its never going to be competitive with an even moderately modern ASIC.
