[JPC] x86 Emulator Written in Java

post #1 of 23
Thread Starter 
Quote:
What systems will JPC run on?
Any with a JVM and enough memory (64Mb in the current version, we can configure it to use less if necessary). This includes x86, PPC, ARM, SPARC, and other CPU's, in different platforms ranging from PC's to mobile phones. To date, we have tested JPC on x86 PC's, a Nokia N95 mobile phone, and an ARM 9 development kit. JPC is written in Pure Java, with not a line of native code, thus taking full advantage of Java's cross-platform features.

See JPC In Action for some of the systems where we have already tried JPC.

What operating systems will JPC run?
In principle, we can run any OS that runs on an IBM PC, including Linux, DOS, and Windows. This includes systems for which there is no longer any available support; e.g. JPC is a safe environment in which to run legacy Windows 95 code. We are currently developing more x86 execution modes, have tested DOS and are now developing further Linux compatibility.

Will JPC run run Linux?
NEW! Yes, JPC can run Linux! Try the online Linux demo or check out other ways to get JPC.

How fast is JPC?
NEW! At the current time, JPC is running around 20% of the processor's native speed, and we still expect speed improvements in the near future. Moreover, we have seen that in some circumstances a HotSpot JVM can outperform gcc-compiled C, so we believe a lot more is possible.

I'm thinking hardware developments might arise from this emulator, but i won't call anything until we see if this gos anywhere user-wise.

Yeah definitly, I know someone who's not going to be happy though: Intel/AMD.

My thoughts exactly, non-x86 processors might squirm their way into mainstream and take chunks of AMD's and Intel's income.

Hmmm... Java = slow. x86 emulated by Java = really slow.

The FAQ states an 80% performance hit, I would expect real world performance to be even worse than that. It's a virtualization technology anyway - it requires a JVM to run on (and thereby an underlying OS).

Yeah that is 3 layers of potential bugs.
