NETWORK-TYPE COMPUTER SOFTWARE SYSTEM DESIGN SUPPORT METHOD

摘要

Provided is a design support device wherein the design step pertaining to performance issues which is one of the serious causes for malfunction is ameliorated and development costs associated with improving the quality of embedded software and reducing the number of back track steps are reduced. A design support method for an entire system in which a plurality of computers installed with an application processing program is connected by means of an information transmission means. At least the priory, activation cycle, execution time and execution frequency are defined for each task constituting the program installed on each computer. The execution time for the execution flow of the tasks is calculated by using a step for defining the execution flow of the tasks for each program, a step for defining the transmission time of the information transmission means, and the priority, activation cycle, execution time and execution frequency defined for each task. The combination of the programs executing a process in conjunction with one another and over the plurality of computers is defined. The performance of the entire system is predicted from the minimum execution time, maximum execution time and execution time distribution of the defined combination of programs.
