Embedded Systems
Computers are not just PCs
 “Embedded systems”
– Software systems “embedded” inside consumer electronics,
automobiles, sensors/actuators, …, etc.
 In fact, 98% of computing devices are embedded systems
– By 2020, over 40 billion embedded processors are predicted to be
sold annually [ARTEMIS Joint Undertaking (EU)]

What is “Real-Time”?
(Hard) Real-Time
 Computer must process the given jobs within a specific amount
of time (referred to as “deadline”)
PCs are NOT hard real-time systems
 Users can wait until
amount of time
to disappear for practically indefinite
Embedded systems ARE real-time systems
 E.g., Automobile must cause its brakes to work immediately
– The time MUST be assured to be upper-bounded; otherwise, …
 Same for other embedded systems
– Because embedded systems interact with physical environments

Real-Time OS
Real-Time Operating System (RTOS)
 Operating system with real-time assurance
 Multi-task (multi-thread) model
– Simplifies programming of operation workflows
 Task switching with real-time assurance
Response time not bounded

5
Real-Time OS
Is RTOS really needed?
 Is it practical for application programmers to write application
codes to assume real-time behavior on multiple tasks by hand?
Apparently too complex to handle
 The use of event-driven OS is thus limited to extremelyconstrained devices & simple application scenarios
Copyright © 2014 by T-Engine Forum., All Rights Reserved.
6
Real-Time OS
Then, why not Linux or Android?
 Too heavy to ensure hard real-time, even when real-time
scheduler is selected
Let’s compare the boot sequence
Linux (typically boots with 10～ secs)
Copyright © 2014 by T-Engine Forum., All Rights Reserved.
T-Kernel 2.0 + T2EX (boots instantly)
7
TRON Project
TRON Project
 Started in 1984 to build an ideal computer architecture
 The vision we pursue has been HFDS (highly functional
distributed system)
– a.k.a. “IoT” (Internet of Things), Ubiquitous Computing, M2M, …
One of the most important contributions is the
standard embedded real-time OS (RTOS)
 ITRON (Industrial TRON) family (1987～)
 T-Kernel family (2002～)
Copyright © 2014 by T-Engine Forum., All Rights Reserved.

The Birth of T-Kernel
Evolution of OS never ends
 As long as the computer evolves
– e.g. 64-bit address space → space-efficient page tables
– e.g. higher clock frequency → low-power (clock/power-gating, etc.)
– e.g. multi-core, virtualization → …
 Embedded technology advanced a lot since ITRON in 1987
T-Kernel is the ITRON for the 21st century
 Based on the ITRON, industrial-proven for long since 1980s
 But with major revision to be adopted for computing technology
of the 21st century
Copyright © 2014 by T-Engine Forum., All Rights Reserved.
10
T-Kernel
Additional T-Kernel Features
 Open source
– The source code for T-Kernel is distributed for free
– Anyone can use it, alter them, and sell them
 Higher compatibility
– Achieved by the reference source code
– The original source code defines the specification, with no
ambiguity
 Middleware and applications made reusable
– High compatibility makes software no longer strongly tied to
specific board or chip
– Minimize the cost to develop richer embedded application systems

 Not always, but YES
 e.g. engines and motors
– When they rotate with 6,000 times per minute (6,000rpm), they
rotate 36 degrees in 1 millisecond
 e.g. network communications
– Inter-frame gap of Ethernet (10Mbps): 9.6μs
– Initial retransmit time of data-link layer protocols
(incresed by exponential backoff): 10μs～200μs

Our Vision (2014)
Still the same, but with concrete technologies
Copyright © 2014 by T-Engine Forum., All Rights Reserved.
98
Towards an IoT Architecture
Integration of T2 and u2 (uID Architecture 2.0)
 Embedded systems are no longer separate devices
– In the IoT age, they are to be inter-connected
 Now, we are merging our two main architectures: T2 and u2
– T2: Device-side architecture
– u2: Server-side IoT information architecture
 e.g., device-control architecture
– Semantic control of houses/buildings
(e.g., “set room temperature to 20℃)
Copyright © 2014 by T-Engine Forum., All Rights Reserved.
99
6LoWPAN
One of the key component in T2+u2 is IPv6
 “The Internet” is the only-one, world-wide open-ended network
 IPv6 is crucial for IoT, when billions/trillions are connected
– IPv4 address is not sufficient for end-to-end connectivity in IoT
6LoWPAN
 “IPv6 over Low-power Wireless Personal Area Networks”
 Enable IPv6 communication over resource constrained nodes
– Including simple sensors/actuators
Copyright © 2014 by T-Engine Forum., All Rights Reserved.
100
Marriage of T-Kernel & 6LoWPAN
T2 and 6LoWPAN is the best combination for IoT
 Internet of Things needs lightweight system and network
– For the network, 6LoWPAN is a promising solution
– For the system, lightweight framework is needed
 Embedded systems need RTOS (real-time OS)
– For practical embedded systems, RTOS cannot be omitted
– Can handle simple sensors/actuators with event-driven OS, but not
the usual consumer electronics, etc.

6LoWPAN Border Router
6LoWPAN Border Router (6LBR)
 Router that connects IoT (6LoWPAN) and the Internet
 Made with T-Kernel 2.0 + T2EX
– Fast, responsive, and real-time
– Boots very fast (from SD card in less than 0.3 seconds)
• In contrast to Linux-based 6LBR from other company, which takes more
than 30 seconds
• An they often swaps to microSD card, causing seconds of no response
Copyright © 2014 by T-Engine Forum., All Rights Reserved.
105
6LoWPAN Border Router
Using T2EX, 6LBR was implemented efficiently
 Basic parts implemented in 2.5 man months
 Richer functions implemented with ease using T2EX
– Web Administration, CoAP/HTTP Conversion, etc.
