Abstract
A special directly executable instruction, Fetch Instruction Operand Address (FIOA) is accessed in response to encountering a complex non-directly executable instruction. Execution of the FIOA instruction causes generation of control signals for address calculation of the operands in the non-directly executable instruction by the same I phase hardware used by other directly executable instructions.
