1. A microcomputer resource utilization estimation program for operating a computer as:
- a retrieval means for retrieving a model from a memory medium; and
a calculation means for calculating an estimated amount of microcomputer resource utilization of the model retrieved by the retrieval means based on the estimated amount of microcomputer resource utilization of a component in a model stored in the memory medium.

Abstract
A development process of an engine ECU program is comprised of a system design stage for a model creation, a software development stage for a source code and object code generation based on the model, and a system testing/matching stage for testing a relevant object code on an engine ECU of an actual vehicle. In this development process, a microcomputer resource utilization estimation program calculates and displays the total amount of microcomputer resource utilization by an object code generated from the relevant model, based on the estimated amount of microcomputer resource utilization of each component block in the relevant model.
