Interesting, indeed! Thanks for sharing!

That sounds remarkable. Could it be be used to make something like this?

Cheers,

I've been playing for a while with the st-microelectronics line of arm processors, namely the stm32f7-series.

Microcontrollers have come a long way from the pic16f84 when I was first stunned by them.

The stm32f7 has cortex-m7 core and go up to 216MHz. I've been long waiting for it's successor the stm32h7 that goes 400MHz. Finally they've released it!

These st micros have an FMC, flexible memory controller and they directly connect to multiple memory interfaces. SDRAM, SRAM, QSPI etc.

Using the m68k cpu emulator from MAME there could be a software cpu emulator card for the Amiga. (or without binary compatible a thumb2 native card)

With bit of glue logic and tweaking (using the FMC NAND interface or something else) the stm(f/h)7 could be used on a accelerator card. STM32F/H can address upto 512Mbytes of SDRAM and same amount of SRAM and what else.

I've butchered the AROS code to distinguish between arm and thumb(2) code but I'm unable to make a gcc crosscompiler for AROS using it.

I've been using the ARM embedded compiler provided by ARM limited when coding for different ST boards (stm32f7-discovery and Waveshare 746)

My Linux gcc (Fedora 27) is unable to compile the 6.3.0 gcc as the code neened to compile would require the use of -fpermissive and I haven't yeat looked for where to put it.

I have a sinister plan in my mind that if AROS is ever to be able to use the said mcu then I'd stole it and use it on my never ending CNC project and control my CNC Bridgeport, or 3D printer...
