 What are wireless technologies?
 Embedded System Development Specifics
 What is Software Engineering?
 Embedded System Training Center (ESTC) curriculum
CHALLENGES FOR GRADUATING STUDENTS
Graduating students have the good knowledge in
computer science
 Mathematics
 Programming languages
 Basics computing techniques etc.
But! They don’t have sufficient skills and experience in
 Specific software development domains
 Software development process
SOLUTION FOR STUDENTS
Embedded System Training Center
 Specific software development domain
 Embedded software
 Wireless technologies
 Specific software development process
 Software engineering in Japan and USA
WHAT ARE THE EMBEDDED SYSTEMS?
Embedded systems:
 Computer system designed to do one or a few dedicated
and/or specific functions often with real-time
constraints.
 Embedded as part of a complete device often including
hardware and mechanical parts
Embedded software:
 Software for embedded systems
 Equipment (hardware) and software part of the product
shall be considered together with equipment
APPLICATION OF EMBEDDED SYSTEM DEVICES
 There are some embedded systems in every electric and
mechanical systems.
 Automobiles, Train(Shinkansen), Aircraft, Digital Camera, Digital
TV, Air-conditioner, Robot, Mobile phone, etc.
CASE EXAMPLE: EMBEDDED SYSTEM USED IN CAR
High-end car:
More than 100 ECUs embedded in a network
About 7,000,000 lines of source code

EMBEDDED SOFTWARE DEVELOPMENT SPECIFICS
Resource constraints
 Cost limitations especially for the mass products
 Low RAM, CPU usage
 Time constrains (real time response).
 Low power consumption, operating environment (e.g.
temperature), weight
→ Real Time OS are used
Quality and Reliability
 Malfunction of the equipment directly related to system
malfunction
 Higher cost of recovery system
 Customer expectations for equipment reliability
FUN OF EMBEDDED SOFTWARE DEVELOPMENT
 Purely algorithmic programming
 Direct work with hardware and OS entities, allows to
understand deeply how your device works – phone,
gadget, computer
 Our target is not tiny assembler written code, it can be
even RDBMS for small devices
 Kind of hacking and sometimes
 Allows to work on variety of platforms
(hardware, OS)
WHAT IS SOFTWARE ENGINEERING?
 Legitimate engineering discipline
The application of a systematic, disciplined, quantifiable
approach to the development, operation, and maintenance of
software; that is, the application of engineering to software
(IEEE definition)
 Recognized profession
 Applies Computer Science theory and practical result
 The aim is: solving of the customer’s problems with
computing means
 Quality is the crucial point
WHAT IS SOFTWARE ENGINEERING?
System approach
 Analysis
 Identify activities and objects
 Define the system boundary
 Consider nested systems, systems interrelationship
 Synthesis of solution
 Creation of solution for system from subcomponents
solutions
