Aren't these MCUs predominantly ARM-based, with some RISC-V thrown in?
I see no contradiction in the desire to support x64 (because it would be ridiculous not to), ARM, and likely RISC-V, but not the venerable but now-fringe architectures like MIPS or Sparc or 68040 or even x86.
- kjs3 5mo agoThe author can do whatever they want. But if all you want to support is x86-64, ARM64 and maybe some version of RISC-V, don't crow about how 'extremely' portable you are. At best, you don't know.
- Brian_K_White 5mo agoportable is a different word from ported.
- kjs3 5mo agoYes, my grasp of english is adequate to understand these words. I just think it's a huge stretch of hubris to claim something is 'portable', especially to claim it's "ultra" portable, if you've not done the actual work to port it or only ported it once. For example, people have learned an awful lot about real world memory alignment issues by actually porting something to SPARC. The author is guessing at best. But yeah...for some people "meh, close enough" is good enough.
- floxy 5mo ago>now-fringe architectures like MIPS For those not in the know, Microchip still produces MIPS microcontrollers: https://www.microchip.com/en-us/products/microcontrollers/32-bit-mcus/pic32m/pic32mx https://www.microchip.com/en-us/products/microcontrollers/32...
- magicalhippo 5mo agoAfAIK lots of 8051-based microcontrollers that are quite modern, such as Silicon Labs EFM8 line[1] or STC which in addition to 8-bit 8051's also has 32-bit 8051 variants[2].
