Abstract

The proposal relates to simulating central pro- cessing units (CPUs). A CPU is a hardware arrange- ment with operand register (OR), flag' register (FR) and instruction decoder (ID). The CPU is usually coupled to a memory (M). A simulator is a computer (hardware) which represents the CPU (CPU': OR', IX', ID') and the memory (M') virtually by execut- ing simulation software called model. Usually, the simulator operates CPU' by executing an application program designed for hardware CPU and simulates ID' using a look-up table.
