fx-9860G series has been adopted from Renesas SH3 custom chip is conventional.
From
the time the fx-CG10/20 was released in 2011, fx-9860GII series has also been
changed to the same SH4A custom chip and fx-CG10/20.
fx-9860G series OS execution speed such as built-in BASIC changed to the current
2.0 system from the initial version 1.0 system is now slow to about half.
Because a function considerably improved, I cannot complain.
but,CASIO fx-9860GII SH4A adopted model ... also speed is half ...
What is it to become slow though the OS does not change?
This
add-in tool was created for the purpose of allowing maximize the potential of
new SH4A model of fx-9860GII.
====== Warning!!!
=============================================================
This tool is made to work safely, but unknown malfunction may happen.
This tool can cause damage on your calculator!
Use it at your own risk.
will not be responsible for any damage.
============================================================================
I think that FX does not have a problem in
particular.
However, please be careful.
Because Prizm is fragile, I recommend use by the I/O frequency that is almost
default frequency.
Here
you take a look at how to how much performance up using the tool.
Built-in benchmark does not know only about changes in the CPU core speed and
memory read speed because things simple.
The benchmark of built-in BASIC use
N-queen (here)
The
benchmark of add-in, use Dhrystone2.1. (CASIO SDK v1.0 optimize option: size)
Because Dhrystone itself is a small program enough to fit in the cache, also
available Dhrystone 100 times unroll it exceeds over 32Kbyte instruction cache size.
Initial OS1.05 is fast nearly twice.
Overclocking in SH3 can further performance up when reduce
wait.
The
following is the result of the fx-9860GII of SH4A,Although the default wait of
ROM is too many.
But,just to make the wait setting similar to the SH3 model.,will be nearly
twice as faster.
Since it is to raise the bus clock it is necessary to increase the wait value
increase of performance as in a high clock is becoming
growth rate turns worse.
BASIC with USB in becomes considerably fast, but it is thought whether it is
a problem only for built-in BASIC& application because there is not influence in
the Dhrystone.
I always want to do it like always with USB, but
there is not been able to touch in this tool for the do not know how yet.
I will try to benchmark even fx-CG10/20 Prizm. (use Prizm SDK 0.3)
fx-CG10 / 20 is inferior benchmark results than the fx-9860GII for a little slow
memory speed, but USB speed problem does not occur with fx-CG10 / 20 Prizm.
