Title:

Performance evaluation of a multi-core system using Systems development method utilizing Reverse modeling and Model-based Simulation

Abstract:

I propose to apply Systems development method utilizing Reverse modeling and Model-based Simulation(SRMS), in order to solve the issues of derivational development. Derivational development is a development method for developing derived products based on products already been released. Many organizations developing embedded system have been applying derivational development to improve development efficiency, time-to-market, and product quality.
However, applying derivational development to large-scale embedded systems in a traditional way to performanec requirements of higher functionality is of high risk. In addition, as requirements of embedded systems for dependability are extremely high, the dependability of development process and safety of the product must be proven by evidence. Therefore, there is a possibility to significantly inhibit the evidence of dependability on embedded systems by continuing derivational development over many years. We apply SRMS in order to solve these issues.
In this presentation, I propose a methodology to solve issues of derivational development by applying SRMS to an SoC Equipped Multi Function Peripheral/Printer. Performance evaluation and energy consumption estimation of SoC are performed in the early stages of the SoC development. Estimating the performace and the energy consumption by a high level of abstraction model-based simulation. Because at the early stages of SoC development, modeling with a high level of abstraction is required for both the system architecture of the SoC and the behavior of the System.
The proposed method is applied for an actual embedded system in an MFP - Multi Function Peripheral/Printer. Proposed method SRMS is promising to solve the issues of derivational developmnrt in the embedded system development.

Bio:

Yoshifumi Sakamoto is an Executive Project Manager of IBM Japan Ltd., and in charge of principal consultant of Advanced Information Technology for automotive. I received the Ph.D. degrees in computer science from Kyushu University, Fukuoka, Japan, in 2014. I was engaged in research of Systems development method utilizing Reverse modeling and Model-based Simulation in the graduate school of Kyushu University.
I joined IBM in 1985. I was responsible for the design and development personal computers, embedded systems and ASIC/SoC. After that, I was responsible for the project manager of ASIC and SoC development project. I responsible for the program manager of the multiple SoC development, and became a technical consultant to apply an advanced information technology into automobile. Currently, I am working as a technology consultant of an automotive control system and In-Vehicle Infotainment system.
