Abstract
An emulator system solving a problem of conventional emulator systems by recognizing a task execution history. In conventional systems, it was necessary for a microcomputer to incorporate a specific task for storing in a memory an identification number and switching time of a task to be executed next in a program to be debugged. The novel emulator system includes a first detector for detecting a write cycle of a microcomputer in which the identification number of a task to be executed next is recorded. A second detector detects the start cycle and end cycle of an interrupt. A measurement memory stores the timing of the write cycle and the timing of the start cycle and end cycle of the interrupt.
