AXC51-CORE (AppoTech Inc.)
used in
AX208 SoC
Notes:
AXC51CORE:
somes sources indicate that the extended opcode encoding may change
on some CPU models despite all being 'AXC51CORE' however we lack solid
information on this at present.
AX208:
The CPU has 0x2000 bytes of internal ROM mapped at 0x8000-0x9fff providing
bootcode, operating kernel and many standard library functions
