Pozwoliłem sobie "odkopać" ten wątek, z racji faktu, że Gunnar w dniu wczorajszym na forum Apollo Knowledge w najkrótszy możliwy sposób podsumował obecny stan rozwoju
68080. Ponieważ to informacje z absolutnie pierwszej ręki, to mam nadzieję, że to rozwieje najczęściej powtarzające się wątpliwości odnośnie projektu.
To give you an overview what the Vampire 500 currently includes
Apollo 68080 CPU (100% 68K compatible)
Apollo fully supports _EVERY_ CPU instruction of the 68000/68010/68030/68040/68060
Apollo 68080 supports _ALL_ 68000/68020/680x0 Ea-modes.
Apollo 68080 supports selfmodify code operations.
So code doing this which worked fine on 68000, but fails on 68030/68040 .. can work again on 68080.
Apollo 68080 can max execute up to four 68k instruction per clock cycle.
In Amiga benchmarks the Vampire scores like an 68060 @100-160 MHz
It obvious that APOLLO 68080 is very fast, sometimes for running ancient games the best compatibility comes when running slower.
We test right now a user-selectable
"turtle-mode" which allows running e.g Games in a a speed much closer to original.
Vampire2 comes with 128 MB fastmem (memcopy speed
~ 300 MB/sec)
The Vampire2 includes a FAST-ATA IDE-controller, with peak 16 MB/sec. In AMIGA HD benchmarks we measured up to 13 MB/sec peak doing real transfers.
The Vampire2 includes an SD-Card interface for easy data-exchange.
The Vampire2 has digital Video out - SAGA.
Which support many different GFX modes
Up to 1920x1080 with up to 24/32bit per pixel.
(...)
Apollo has its own MMU.
It has more/partly other features than 68K MMU.
As you certainly know previous 68k CPUs had 1 bus.
Apollo is different.
Like some DSP designs APOLLO supports using 2 buses fully in parallel. This more advanced bus design also requires a different MMU.
68882 is a quite old and very slow FPU design.
APOLLO has an 68k compatible FPU which is fully pipelined - and is much more advanced then even the 68060 FPU.
APOLLO's FPU is fully code compatible to 68K FPUs.
The FPU is currently under testing.
