ABSTRACT:
An emulation apparatus is connected to a host computer and a target system for verifying the operation of a program written for the target system. A microcomputer in the emulation apparatus executes the program written for the target system. In an undo mode, the execution of a program is halted at the end of the execution of each instruction. At that time, information on relative bus cycles is stored in a relative-bus cycle area of a memory. The contents of data and control registers in a target system are acquired and stored in data-register and control-register areas.
