Here is an article with all the details about a new chunk of progresses on #UltimaVM and the new project's mascot Luma. Still lots of work to finish to get the first beta release out, but hey I am moving forward!

Finally had some time to update #UltimaVM presentation article with all the latest improvements. I still need to publish the latest release of the Reference Manual, but at least the article is now up-to-date:

If you love Assembly, I am sure you'll love my #UltimASM #DSL it allows you to design the Assembly of your dreams or to code in #6502asm , #MC6809 , #mc68000 and even #VAX #ASM on #RISC_OS (and all other supported platform by my #UltimaVM).

Want to know more? Come at the RISC OS London Show Saturday 25th October!

Added #JVM Stack Operations mapping to my #UltimaVM (see link). But I am thinking of adding indirect adressing:

PUSH.U64 [r0-r1] Push mem val from addr in r0 to addr in r1
PUSH.F32 [r0] Push val at mem addr in r0

Is it possible to implement a 64bit architecture on a 32bit CPU and OS from the 80s and nest multitasking? YES, clearly 😎 UltimaVM on #RISC_OS inside the RO TaskWindow, and the system is perfectly stable! This is PMT within PMT within CMT 🤯 - Oh and Ultima can also spin up multiple schedulers (using pthreads and a VM context for each of the scheduler)

🤯 Last night I had the time to complete the last planned addressing modes for the LDR and STR instructions in #UltimaVM #bytecode. So now all the forms in the picture are supported! To come up with an efficient encoding for all of this wasn't funny. 😂

Both LDR and STR supports also -, *, and / on top of + operation to calculate an address. Obviously also LSR is supported. Performance are unaffected.

Exciting update on #UltimaVM: I've finished the core work for platform-specific syscalls and begun testing on #macos. Next up: #riscos. Plus, I'm exploring the integration of Jeffrey's SMP work to enable UltimaVM threads to run on multiple cores. Stay tuned for more breakthroughs! 🚀
