Hi people, I'm looking for simulators of 64-bit processors for my 32-bit PC and i've found one.
"qemu-system-x86_64" works simulating a x86-64 linux as slamd64, ubuntu, etc. http://fabrice.bellard.free.fr/qemu/status.html indicates that x86-64 is OK for System emulation but is not supported for user emulation. The problem is that the x86-64 ISA is too complex to develop i an aplication that generates assembler or machine code like CacaoJVM, JCVM, Flex, ... x86-64 is CISC and not RISC. It will be easy if the 64-bit CPU is RISC. I don't know what 64-bit CPU that will dominate in years 2008 .. 2013. I'm not sure if PearPC or PSIM simulates PowerPC64 ISA but the "Full-System Simulator for IBM PowerPC 970" said that it does but it's closed source. I'm not sure if Sulima simulates Sparc64 ISA from http://ccnuma.anu.edu.au/sulima/0.4/sparc-sulima-0.4.tar.gz but it goes to v0.4 version, not v1.0 :( The IA-64 CPU is monstruous and too complex because there aren't known open source applications that target IA-64. I don't know if that simulator exists or not. After talking, my question is: What popularity of CPU will dominate in the years 2008 .. 2013? By example, 1. x86-64: 75% 2. ppc64: 15% 3. sparc64: 5% 4. others: 5% Any opinion to the respect? Sincerely yours, J.C.
