• Is ARMv7-M3 thumb instructions compatible to ARMv7-A thumb?
    Hello guys, I am trying to verify some features of ARMv7-M3 in a software simulator platform for ARM. But this simulator only support ARMv7-A ISA. Is ARMv7-M3 instructions compatible to ARMv7-A, especially...

  • thumb 2 instruction set
    The thumb 2 instruction contains both the instruction sets( best of both worlds) ARM and THUMB. So my question is how does processor come to know that the fetched one is 16 bit size instruction...
