Hello, Dear Qemu developer!

My name is Eugene. I am a student of Mathematics and Mechanics St.
Petersburg State University Faculty.

*Why i am writing to You:*

We (our students group) need to design and develop* Disassembler, that can
parse (recognize) one **machine instruction in a minimum available clock
(tact cycle) time. *Or such Disassembler, that can parse ALL instruction
with max speed in average. In this case, Average means ratio of all
instruction to all execution time.

*Today:*

We have developed rough disassembler based on Intel encoding table (from
information in documentation volume "Instruction optimization"). And now we
need to compare speed of our disassembler with others (with Yours too). And
the second task is to simplify our model of disassembly (We consider 3
models of building Diassembler - Finite State Machine, Jump from a Table
and Block-Diagram, witch we realize with conditional crossing).
So, in our Disassembler, that we call *Speedy ( Block-Diagram was used) *-
we can simply set time counter at the begin and at the end of parsing
instruction. But we can't repeat this thing with Yours Disassembler. It
follows us ask You for help us.
*
What are we ask:*

We will be very glad and grateful, if You can send to us pure *DisAsm code
(DLL with parse function or another files)*, which speed we can measure. If
You have another materials(maybe any speed grafics, or a tests set that can
help us) or thinking of this theme  - it would be very good.

What is the speed of parsing one (or more) instruction in Yours
Disassembler?
Have you made any verification tests? (Now we are developint it)
What is the metric, that You estimate the speed of Disassembler?



Thanks for reading and sorry for my mistakes,
Sincerely,
Eugene.
