altenative 32 bit processor

Started by Jerome March 15, 2004
looking for 32 bit cpu with MMU, FPU and fairly high
throughput benchmark (> 300 MIPS) that is not PowerPC
or Pentium based... trying to stay clear of Intel, AMD,
Motorola, AMD....  

any recommendations/experiences ?

thanks!

SPARC will get you there if you accept a 64 bitter. Will not let you stay clear of Sun and TI though... Main problem could be that they want to stay clear of you :-) Have no clue if they will sell you chips. My guess is that MIPS will get you there as well. Most ARM do not have FPU, but maybe the new OMAP2 from TI with ARM 11 could do the job if you can get hold of them. -- Best Regards, Ulf Samuelsson ulf@a-t-m-e-l.com This is a personal view which may or may not be share by my Employer Atmel Nordic AB

Why not an IBM PowerPC. Failing that, try one of the MIPS CPUs (e.g. PMC-Sierra has a powerful MIPS with FPU). Does ARM have an FPU? -- - Mark -> --

I believe there are ARM9 CPUs around that run that fast. I won't tell you to look at the Intel StrongARM :) But you can start at the ARM web site. If you nose around you will find a vendor list of chip makers. If you can't find it, I can email you a copy. They do hide it pretty well. -- Rick "rickman" Collins rick.collins@XYarius.com Ignore the reply address. To email me use the above address with the XY removed.

ARM9 normally does not have the FPU and is more typical 200 MIPS. You will need ARM11 and there are not plenty around. -- Best Regards, Ulf Samuelsson ulf@a-t-m-e-l.com This is a personal view which may or may not be share by my Employer Atmel Nordic AB

This list does not include TI, Analog Devices, Philips, Infineon, NEC, Renesas, MIPS, ARM... so plenty to research...

How about Renesas (ex. Hitachi) SH4? 300MIPS for the "slowest" part, 430MIPS for the higher end devices. (according to Renesas web site) Jens

Depending on what you really want the FPU for (if it can be 
replaced by DSP fixedpoint instructions) the TriCore might 
be interesting:

Probabely a bit slow on throughput though. But then again, 
it _is_ a Triple (independent) Core architecture. Never used
it myself, but it does look intriguing.

MIPS sounds like a good alternative ..... will definetely look into that... sounds like ARM does not support FPU.... just a follow up... I have nothing against the IBM,Motorola,Intel,AMD products that I identified... as a matter of fact we use them quite a bit.. its just that this embedded project requires a non PowerPC or Pentium (x86) CPU...... hence my difficulty in finding CPU's that rival them... still need to look for 2nd choice to MIPS...

VR4133 from NEC. VR7701, if power consumption is not a big concern.
