Specs of the virtual machine this will run on:
Program to execute is not stored in the system memory, it's just a separate list of instructions.
65536 virtual registers, 16 bits wide, can also be used as 8 bits. r0-r65535
65536 virtual floating point registers (64 bits double precision) fr0-fr65535
100K virtual registers, 16 bits wide, can also be used as 8 bits. r0-r99999
reserved 99000 - 99099 : WORD registers for syscall arguments and response value(s)
reserved 99100 - 99199 : BYTE registers for syscall arguments and response value(s)
100K virtual floating point registers (64 bits double precision) fr0-fr99999
65536 bytes of memory. Thus memory pointers (addresses) are limited to 16 bits.
Value stack, max 128 entries of 1 byte each.
Status flags: Carry, Zero, Negative. NOTE: status flags are only affected by the CMP instruction or explicit CLC/SEC,
