Q. Instruction per cycle in RISC?
One instruction per cycle: A machine cycle is total time taken to fetch two operands from registers perform ALU operation on them and store result in a register. So RISC instruction execution takes about same time as micro-instructions on CISC machines. With these simple instruction execution instead of micro-instructions, it can use fast logic circuits for control unit, so increasing execution efficiency further.
