* 1-operand ( one-address machines ), so called accumulator machines, include early computers and many small microcontrollers: most instructions specify a single right operand ( that is, constant, a register, or a memory location ), with the implicit accumulator as the left operand ( and the destination if there is one ): load a, add b, store c. A related class is practical stack machines which often allow a single explicit operand in arithmetic instructions: push a, add b, pop c.

1-operand and so
** RISC — arithmetic instructions use registers only, so explicit 2-operand load / store instructions are needed: load a, reg1 ; load b, reg2 ; add reg1 + reg2 -> reg3 ; store reg3, c ; unlike 2-operand or 1-operand, this leaves all three values a, b, and c in registers available for further reuse.
