Architecture 2.1

Archetecture:

8 registers - ABCDEFGH
  refered to in code as rrr or sss - just means "One of the registers"

32 bytes of adressable RAM


ROM[A] means ROM at adress in A register
RAM[A] means RAM at adress in A register

11 bit instructions

000nnnnnnnn - send nnnnnnnn to A

00100rrrsss - save value in rrr to sss

01rrrsssooo - perform operation ooo on rrr and sss -> B
 ooo -
  000 - AND
  001 - OR
  010 - XOR
  011 - ADD
  100 - NAND
  101 - NOR
  110 - XNOR
  111 - SUB

10000rrrccc - jump to ROM[A] if rrr is ccc
 ccc -
  >=< or multiple

101dddddddd - unconditional jump to ROM[dddddddd]

11w00000rrr - read/write RAM[A] to / from rrr

11wdddddrrr - read/write RAM[ddddd] to / from rrr (fast access for first 32 bytes ROM)
