Re: Acorn Archimedes

BTW I will sue eab in 2018 over advocating piracy, as I will have a company developping games, as this is something I really didn't like, when the moderators do not condemn piracy and express the idea it didn't reduce the number of originals sold, and thus that made no harm to games makers. Why not...

Re: Daimakaimura (Ghouls 'n Ghosts) for the Atari STE

question: sprite on a STE when is it better to blitter and when is it better to use CPU? On the Atari STE I would say that you cannot beat the Blitter for this task. Especially when you need space for animation frames where the precalculation is not an option at all. +1 Hardware wins always.... Use...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

I find memory protection very useful. I had very stable system with it enabled on my Milan060. It is shame it is not available for the FireBee. When you find what software make troubles with MP enabled you just dont use it anyway. I had no need to use such software at all. If software doesn't work ...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

In all case if we want take advantage of 68080 Mint need to be updated (more register to save, MMU ...) but Mint can work as it is and already run under 68080. Who use protected mode? near nobody, perhaps some developpers as I do to remove bugs I'd rather have memory protection in Mint if at all po...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

Appolo core support an MMU but not compatible with other 68K CPU, Appolo core support FPU but up to now there was not enough memory on Vampire V2 card, so I suppose it will be available on the V4. We can work to have good support of SAGA in Emutos It should really just mimic the 040 MMU or the 030 ...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

The stand alone version is more interesting than the CPU card version. This is depending on how good the SAGA emulation of AGA is and what extra features it adds. No Atari support however as expected. No MMU or FPU either? Appolo core support an MMU but not compatible with other 68K CPU, Appolo cor...

If extra video modes are added emutos could be extended to handle them. If you added a 256 colour mode for instance.

ARM2 has no instruction, uninterruptible, to do synchronisation (you are speaking about an instruction allowing to easily implement semaphores, right ?) But it is available from the ARM3, and then in the ARM250. It is why I 'fight' when people say the CPU inside an ARM250 is an ARM2 : it is not. Th...

Re: Processor comparisons

I don't think the RISC chips were designed for compilers and the CISC chips for humans to be able to program in assembler. I would say exactly the opposite. At least for the ARM chips. For the bitfield instructions, that looks very complex to me ; I need an example with what it does in plain, under...

Shifts cost no additional cycles on any instructions, as long as they are a constant. I make heavy usage of this feature in my routines.
