SYSTEM EVALUATING DEVICE

PURPOSE:To provide a system evaluating device capable of executing the kind of device selection on one host computer by automating the acquisition and totalization of evaluation items along with the kind of device selection of a microcomputer. CONSTITUTION:Microcomputer A and B compilers (including an object preparing tool such as a linkage editor, etc.) 1 and 2 corresponding to plural target computers A and B and microcomputers A and B simulators 3 and 4 are mounted on the same host machines so as to automatically select the kind of the device such as a microcomputer suited to evaluation reference based on respectively obtained execution performance evaluation data and static performance evaluation data. Thus, performance evaluation at the time of selecting the kind of computer can efficiently be executed on one host computer with high reliability.
