We assume that instructions are unsigned numbers.
All instructions have an opcode in the first 6 bits.
Instructions can have the following fields:
`A' : 8 bits
`B' : 9 bits
`C' : 9 bits
'A' : 8 bits
'B' : 9 bits
'C' : 9 bits
'Ax' : 26 bits ('A', 'B', and 'C' together)
`Bx' : 18 bits (`B' and `C' together)
`sBx' : signed Bx
'Bx' : 18 bits ('B' and 'C' together)
'sBx' : signed Bx
A signed argument is represented in excess K; that is, the number
value is the unsigned value minus K. K is exactly the maximum value
