Mengenal Embedded System

Summary

In this video, the concept of embedded systems (sistem tertanam) is introduced. An embedded system is a microprocessor- or microcontroller-based system designed to perform specific functions and cannot be reprogrammed by the user. The video highlights examples such as ultrasound devices compared to laptops to show the difference between systems that can perform multiple functions and those that are specialized. The video also discusses the characteristics, advantages, and disadvantages of embedded systems, such as their ability to work in harsh environments, limited functionality, and fixed hardware.

Takeaways

• 😀 An embedded system, or 'sistem tertanam' in Indonesian, is a system based on a microprocessor or microcontroller designed to control specific functions and cannot be reprogrammed by the user.
• 😀 An ultrasound machine (USG) is an example of an embedded system, as it only performs functions related to ultrasound processes, unlike a laptop that can run multiple applications.
• 😀 Embedded systems are equipped with computing power, meaning they have processors that convert inputs into expected outputs.
• 😀 They are designed to work in outdoor environments, withstanding external disturbances such as vibrations and dust, unlike IT rooms or server rooms which have climate-controlled environments.
• 😀 Embedded systems perform specific tasks that are pre-programmed and cannot perform additional functions beyond what was designed for them.
• 😀 The first advantage of embedded systems is that they do not require sequential programming. Unlike traditional programs that run in a specific order, embedded systems allow non-sequential coding.
• 😀 A second advantage is that embedded systems can be interrupted during processing, allowing for flexibility in managing tasks.
• 😀 The third advantage is that multiple parts of the embedded system can operate simultaneously, optimizing performance.
• 😀 The fourth advantage is that embedded systems can manage critical components in larger systems, ensuring overall stability and function.
• 😀 The main drawback is that embedded systems cannot function independently; they must be part of a larger electronic or mechanical system.
• 😀 Another limitation is that the hardware in an embedded system is permanent and cannot be upgraded or downgraded after programming, making it less flexible than general-purpose systems.

Q & A

What is an embedded system?

An embedded system is a system based on a microprocessor or microcontroller designed to control specific functions and cannot be reprogrammed by the user.

How does an ultrasound machine (USG) relate to an embedded system?

An ultrasound machine is an example of an embedded system because it can only perform tasks specifically related to ultrasound functions and cannot run other applications like a laptop can.

What is the main difference between an ultrasound machine and a laptop in terms of functionality?

The ultrasound machine is designed to perform specific functions related to ultrasound, whereas a laptop can perform a variety of tasks and run multiple applications.

What are the primary characteristics of an embedded system?

Embedded systems typically have computing power (a processor), are designed to work in external environments (resistant to disturbances like dust and vibrations), and are programmed to perform specific tasks.

Can embedded systems be programmed to perform any function?

No, embedded systems are designed to perform specific tasks as programmed, and users cannot alter these tasks once they are set.

Why are embedded systems able to operate in environments with external disturbances?

Embedded systems are built to withstand environmental disturbances like vibrations and dust, making them suitable for use in outdoor or industrial settings.

What is one advantage of embedded systems regarding coding?

One advantage is that the programming of an embedded system does not need to follow a strict sequence of steps, allowing for more flexibility in the code structure.

How does an embedded system handle processes during operation?

Embedded systems can handle interruptions during a process, meaning they can be paused or adjusted without completing the task, unlike traditional systems.

What are some disadvantages of embedded systems?

Some disadvantages include the inability to operate independently (they require larger systems), fixed hardware (it can't be upgraded or downgraded), and they can only perform the specific tasks they were designed for.

What should students do for their task after learning about embedded systems?

Students should find at least two examples of embedded systems around them, describe how each one works, and write their findings in their notebooks, noting their name and class at the top.
