[Pearpc-devel] cpu_generic vs cpu_jitc_x86

[Carlos Boneti]

Hi everyone,

This summer I made some quick study (<2 weeks) involving the PearPC. I
came up with some comparative study between the jitc-x86 and the
cpu_generic implementation. Probably things that some [many] you already
know.

You can have a version of the report (2 pages) at the link below.
http://www.boneti.com/pearpc/report.pdf


My CVS version was from 6/2005 and, as a clue, the version of my
cpu_generic/ppc_cpu.cc was the same actually on the server (1.10), the
same for the cpu_jitc_x86/ppc_cpu.cc (1.10).

Well, I hope you find it interesting. If you think that we can take
something out of this report (like some documentation or something), or
just have critics, please let me know.

Thank you,

Carlos

Well, this certainly answers some of the questions I had about
switching to a hybrid model.

I'll likely look into the information more, and such to see if there's
anything deep I can really get out of this study to help with what I'm
doing with PearPC. Thanks for the research though :)

Well, tell me if you want to see the data I found and more or less what.
It's a little mess so I could organize it better for you (even worse
because it's a 6months old work). If you need any workforce for the
task, just tell me. :)

If it's fun for you benchmarking those things, please go ahead. Not
everything there is really optimized..
