29.5 MIPS, OSC: 14.744 Mhz, Core/Bus Clock: 29.488 MHz. It should be faster than 12/15 MHz of TI.

SH7291 classpad300 cpu to ?

HiHi, I ask this question 9 months ago, a respond really made me happy.

I thought my v200 only had a 6 MHz processor
It should be faster than 12/15 MHz of TI.

and the SH-3 should be faster than the m68000 because the SH-3 because it's much newer than the m68000

We know that the ClassPad 's processor speed is fast. You have Ti calculator, so may I ask you which one run faster ?
Posted 26 March 2004 - 04:06 PM
1 + 2 + 3 + ... + 10000
TI's time: 17.12 s
CP gave me result immediately.
But it can be a better algorithm, not only faster CPU.
(ClassPad is slower in list operations.)

When I've tried some other calculation, except lists CP has been faster then TI.

if the cpu operates only on the LH-flank it is slower than one wich operates on the LH and the HL flanks.
Or if the cpu needs two clock cycles to do an calculation then this cpu is slower.
then you can't compare an risc with an cisc prozessor

There is this text:
"La classPad 300 tiene un procesador Hitachi SH7291, RISC de 32 bits. Trabaja a una velocidad de 32 MHz. Tiene memoria de 4.5 MB, 500kb son de memoria en el area de usuario, y 4MB en el ?rea de aplicaciones y Add-ins."
Classpad 300 has a Hitachi SH7291 RISC processor of 32 bits. IT works at 32MHz....

Yes, that`s our web site. We have put that information available to the public, but we are willing to correct it immediatly if something is incorrect. It`s likely for the statement " ..it works at 32 MHz..." not to be so correct, but not every -potential- customer will understand what is a crystal, so telling them that it has a 32MHz crytal inside doesn't add up. We just want to give the most acurate information to the public. But the fact is that, until this moment, we don't know the exact speed of the processor. Is there a program available to measure it, just like it happens with normal computer?.

Just to point out the SH-3 series is remarkably similar to the 68000 - so much so they've been sued countless times by Motorola. Definitely a CISC. Also, "newest" has nothing to do with a CPU's speed - by the early 90's you had 100MHz 68K and the latest incarnations (CF) are up to 333MHz. Low clock speed is simply to save battery life...
>>"anyway, the big difference is that the classpad processor has a RISC (reduced instruction set computer) cpu and the ti's a CISC (complex instruction set computer)
and the SH-3 should be faster than the m68000 because the SH-3 because it's much newer than the m68000"
Honestly, if you want a fast, RISC processor, go with an ARM based calculator like the HP-49G+. The ARM can do a full instruction every 2 cycles, whereas the 68Ks take 8-300 cycles. But obviously processor speed isnt' the main attraction to a calculator.
