Perhaps one for Peter,

Are there any plans to bring the MMExtreme reference design (144 or 100 pin boards) and/or the firmware version up to V6 or V7?

I have both the 144 pin board and the 100 pin Navigator board and could run any testing on either.

Doug.

... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

144 pin MMeXtreme; my absolute favourite chip! Several in operation; five chips in stock awaiting board build. Alas, as a full-time carer, my time to implement is rather limited.

I’m also waiting for an update.
I use all three types of the MMX (64, 100, and 144-pin) in various projects.
They are my favorites, too.

silly question:

geoffg lists on his website:

standard micromite

and

micromite plus.

what is the definition of "micromite extreme"?

It's for the PIC32MZ2048 series ( 64 , 100 or 144 ) pins. ( Other Downloads on Geoffs Website )

Judging by the features, I’d say this is the precursor to the CMM2.

@athlon1900:

thanks a lot.

there I found the downloadable firmware.

Is in the forum an post with the tech specs? the mz is the fastest chip with mips cpu I think. how fast is it in comparision to cmm1 and so on.

This is prior to the compiler so not up-to-date.

At 252MHz the PicoMite is very similar to an MMX at 200MHz, it only lacks 100 I/O pins. Also since last MMX update the PicoMite and MMX commands have very much aligned.

PicoMite V7.00 at 252MHz is average as fast as V5.08 at 378MHz.
That is a 50% speed increase since 5.08
Now need someone to run the PC3 at 378MHz. Might come close to CMM2.

my mmbasic computers has to run an old program of me which is kind of a ecological simulation to test speed.

pico computer 3 at 378 mhz: 3-3.5s per frame
cmm2 4s!

both with option compiled on

The HDMI and HDMIUSB versions run at 378MHz.
BT and BTH versions run at 396MHz.
I don't have a newer manual yet.

Hi Harm,
For a laugh, here are the results for V7.00 RC5 HDMIUSBI2S @ 378MHz (PC3ish).
Because the times were getting silly, these are for 1000000 iterations, so if you want a direct comparison divide the times by 1000.
For completeness I also include the same program compiled automagically by peters mmb2csub script.
Standard MMBasic with Option Compile On.

Standard Compiled MMBasic, this only uses the lowest optimisation level because, even though I tried to stop it the optimiser was making the time for test 2,3,4,5 0.0mS by optimising out the loop completely.
