Robert E Fosdick: Computer emulator with three segment microcode memory and two separate microcontrollers for operand derivation and execution phases. Tracor, Arnold White & Durkee, January 25, 1983: US04370709 (57 worldwide citation)

A microcoded central processing unit (CPU) is used to emulate the macroinstructions of a target computer. Each macroinstruction emulated is divided into two phases, an operand derivation or classification phase and an instruction execution phase. A microcontroller is provided to control each of the ...
