Faster than real-time execution

[frankwmiller frankwmiller.net]

Greetings,

 

I've been contemplating using QEMU for faster-than-real-time execution of SPARC executables on an X86-64 machine.   It appears from the base architecture of QEMU that this is not possible if QEMU is using JIT of the SPARC to x86-84 since the resulting x86-64 will run on the hardware at the processor clock speed and there's not really any way around that.

 

However, is it possible to do something like this.  Execute the SPARC instructions in simulation, i.e. without any JIT, and then since everything is executed as simulated SPARC instructions, essentially speed up time in the simulated environment and execute FRT that way?

 

Thanks
