66MIPS 8bit microcontroller

Google did not give me useful results.
Are there any 8bit microcontrollers available
running at least 66MIPS?

Thanks !!

Just to satisfy my own curiosity. If you require that level of performance,
where does the requirement to use an 8bit processor come from?

Sure--Silicon Labs and Asix have 8051s that run at 100 MIPS. Also
Picoblaze and probably others if you have a corner of an FPGA free.

Tezzaron Semi may have something, although I don't know what is their
product availability, or anything about the company actually.

Does anyone have any experience with their products?

Hey Atmel,

When are you going to up the ante on AVR performance? Why aren't we
seeing 100MHz, 50MHz, or even 33MHz ?

What do folks do with 100MIPS 8-bit controllers anyway? I can think of
some uses if the IO and interrupt latency is similarly low. But these
would be peculiar applications, not mass market.

What market drives Silicon Labs to make 100MIPS 8-bitters, and why
doesn't Atmel compete?

....because Atmel make AVR32, ARM7 and ARM9 devices? Hence my previous
question on this thread. If 66MIPS (?) is required, then where did the
requirement for 8bits come from?

BTW, it is ridiculous but anything running higher then 25MHz is subject
to US export regulations. And it looks like the speed limit for many
microcontrollers is exactly there.

There used to be an idea of "virtual peripherals". Running that fast you
can simulate whatever peripherals by bit banging. Ubicom was strongly
promoting that idea, but nobody seemed to like it.

It would be convenient (in the theory) to simulate exactly what you need
instead of trying to find MCU with all necessary features.

I would guess the market is for people who want to use their familiar
8051 and PIC tools, but want more MIPS.

Perhaps the people originally willing to switch to a non-mainstream
core like the AVR, would be just as willing to switch to an ARM if
they needed more speed. I.e., there is not as large a user base
reluctant to change cores.
