1
An embedded system is an autonomous electronic and computer system, with the goal of executing a well -defined task in real -time.
2
Here we see the first difference from a PC, which is versatile because it can run many types of applications, whereas an embedded system only performs a dedicated function.
3
Furthermore, embedded systems are often invisible to the user
4
because they are integrated within a device
5
that itself serves a function for example a microwave oven an
6
airplane a washing machine etc domains of embedded systems are primarily
7
found in the following areas first we have general computing similar to pc applications
8
but integrated into an embedded system such as smartphones tablets etc
9
then systems control such as motor control automotive applications aviation
10
and navigation systems also signal processing with examples like radar sonar
11
and video compression and finally communication and networks involving information transmission telephony
12
and the internet for example
13
so as you can see there are many embedded systems today
14
embedded systems far outnumber computers in terms of quantity an embedded system typically consists of microcontroller that solves a specific problem,
15
often subject to time and size constraints.
16
A microcontroller is an integrated circuit that combines essential computer elements that includes a processor to provide computing power,
17
a central memory, often limited, containing the program and data, sensors acting as inputs to receive information,
18
such as temperature, vibration, humidity,
19
proximity, pressure, or contact, and actuators or outputs that allow the embedded system to perform actions on the external real world environment.
20
These can include LEDs, display screens, speakers, alarms, or a combination of these, as seen in an airplane cockpit.
21
Finally, embedded systems are equipped with communication means that enable them to communicate via the internet with external applications and end users.
22
This is the phenomenon of the Internet of Things, or IoT.
23
It's important to note
24
that there is a significant difference between embedded systems based on the device in
25
which they are embedded and the complexity of the task they perform.
26
On one hand, there are small -scale embedded systems with very simple hardware
27
and software sufficient for basic tasks like a coffee machine that transforms your coffee capsule.
28
On the other hand, there are advanced and sophisticated embedded systems found in devices like airplanes,
29
designed to facilitate piloting and improve safety.
30
The design of an embedded system typically depends on the characteristics and constraints of the device in which it is integrated.
31
This includes considerations such as weight and size, program size and required execution time, especially for embedded systems with basic hardware.
32
The appropriate hardware to run the software Energy consumption,
33
optimized based on the size and complexity of the embedded system Continuity of operation,
34
which requires embedded systems to withstand harsh external conditions such as vibrations, shocks, temperature variations, and weather And finally,
35
manufacturing costs, determined by the aforementioned constraints Thanks a bunch for tuning in.

注意したい発音
- 「sh」と「zh」の音: vibration /vaɪˈbɹeɪʃən/, aforementioned /əˈfɔɹˌmɛn.ʃənd/, compression /kəmˈpɹɛʃ.ən/, notification /ˌnoʊtɪfɪˈkeɪʃn̩/, navigation /nævɪˈɡeɪʃən/

- 通常の速度で一文ずつシャドーイングし、話し手のリズムに合うまで繰り返します。
- 自分の声を録音して元の音声と比べます。embed, constraint, airplaneなどの単語に特に注意しましょう。
シャドーイングとは?英語上達に効果的な理由
シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
