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.

vibration substantivo/vaɪˈbɹeɪʃən/vibração
complexity substantivo/kəmˈplɛk.sɪ.ti/complexidade
actuator substantivo/ˈæk.tjuː.eɪ.tə(ɹ)/atuador
optimize verbo/ˈɑptɪmaɪz/otimizar
outnumber verbo/aʊtˈnʌmbə(ɹ)/exceder em número, disparidade
telephony substantivo/təˈlɛf.ə.ni/telefonia
equip verbo/ɪˈkwɪp/equipar
dedicate verbo/ˈdɛdɪˌkeɪt/dedicar
aforementioned adjetivo/əˈfɔɹˌmɛn.ʃənd/supracitado, sobredito
withstand verbo/wɪðˈstænd/aguentar
versatile adjetivo/ˈvɜː.səˌtaɪl/versátil

Pronúncia para ficar de olho

  • Os sons de “sh” e “zh”: vibration /vaɪˈbɹeɪʃən/, aforementioned /əˈfɔɹˌmɛn.ʃənd/, compression /kəmˈpɹɛʃ.ən/, notification /ˌnoʊtɪfɪˈkeɪʃn̩/, navigation /nævɪˈɡeɪʃən/
  • Palavras longas — acerte a sílaba tônica: microcontroller /ˈmaɪkɹoʊkənˌtɹoʊlɚ/, complexity /kəmˈplɛk.sɪ.ti/, actuator /ˈæk.tjuː.eɪ.tə(ɹ)/, telephony /təˈlɛf.ə.ni/, aforementioned /əˈfɔɹˌmɛn.ʃənd/

Sons difíceis para falantes de português:

  • Consoante final — sem acrescentar um “i” depois: embed /ɪmˈbɛd/, integrate /ˈɪn.tɪ.ɡɹeɪt/, constraint /kənˈstɹeɪnt/, compute /kəmˈpjuːt/, equip /ɪˈkwɪp/
  • /l/ final — a língua toca o céu da boca, não vira “u”: versatile /ˈvɜː.səˌtaɪl/, capsule /ˈkæps(ə)l/, invisible /ɪnˈvɪzəb(ə)l/

Como praticar com este vídeo

  1. Ouça o vídeo inteiro uma vez sem falar e anote as palavras que você não conhece.
  2. Faça shadowing frase por frase na velocidade normal, repetindo cada uma até o seu ritmo ficar igual ao do falante.
  3. Grave a sua voz e compare com o original, prestando atenção a palavras como embed, constraint, airplane.

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
