The present invention has an display section for displaying an operation state of a program to a user in a time series manner based on program execution history information, an input section for allowing the user to designate a portion of a defect in the displayed operation sate, and an operation analysis section for analyzing a cause of the defect from the portion of the defect pointed out from the user by the input section and from the operation state of the program, and for specifying a solution for solving the cause of the defect. The operation analysis section regenerates the operation state on which the specified solution is reflected, and the display section displays the cause of the defect, the solution and the regenerated operation state to the user.

Information processing apparatus, defect analysis program, and defect analysis method

An improved control system with an embedded microcomputer is described which makes it possible to facilitate procedures for maintenance and modification of the specification and effectively use existing software resources by means of a configurable real-time OS. The real-time OS comprises an operation descriptor for storing control data for controlling the plurality of the tasks respectively, a kernel for controlling the operation of the control system with reference to the operation descriptor, and an interface provided for receiving data for modification of the control system and rewriting said operation descriptor in order to update said real-time OS.
