Abstract
An in-circuit emulator comprising CPUs (microprocessors) of different types, portions of constituent elements thereof being different from each other, a control circuit connected to the CPUs and an external actual apparatus for controlling the operation of the in-circuit emulator, and an identifier circuit connected to the CPUs and the control circuit for identifying differences among the CPUs based upon feature signals from the CPUs inputted thereinto, the in-circuit emulator switching the control circuit to an operation mode suited to the CPU by making use of an output from the CPU identifier circuit.
