Question

If I have a 3 address machine, is my machine more likely to follow RISC or CISC design?

2 addresses?

1 address?

0 address?

Answer 1

RISC is the reduced instruction set and it is used to reduce the total execution time in the instruction set. The addressing modes are lower in the reduced instruction set.

CISC is the complex instruction set computer in which the single instruction can be executed in the low level operation.

1) 2 address:

The 2 address instruction are basically associate with the complex instruction set (CISC).

2) 1 address:

The 1 address instruction is basically associated with CISC ( Complex instruction set) or RISC ( reduced instruction set ).

3) 0 address:

The 0 address instruction is basically associate with either CISC ( Complex instruction set) or RISC ( reduced instruction set ).
