Difference between Embedded System and VLSI

Difference between Embedded System and VLSI

Embedded systems with particular processing capabilities are often associated with integrated circuits (ICs). VLSI or Very Large-Scale Integration (VLSI) procedures may be used to create embedded systems in any smart device that seeks to manipulate data using specialised, developer software. With the aid of this article, you’ll have a better understanding of the distinctions between VLSI and embedded systems.

Embedded System Vs. VLSI

As a result, embedded systems design focuses on generating code that runs on a flexible piece of hardware, whereas VLSI emphasises translating programming instructions into the framework of an integrated circuit (IC).

An embedded system is a kind of technology that is used for a specific purpose and is referred to as such. While an overall computer can do a variety of tasks, an embedded system is more simpler and eliminates a lot of unnecessary technology. Banks, modems, calculators, and mobile phones are just a few examples of embedded systems in use today.

When referring to the sophistication and complexity of an integrated circuit, the term “Very Large Scale Integration” (VLSI) refers to the estimation of the number of gates and transistors present. There are many other acronyms being used to describe integrated circuits, such as VLSI, MSI, ULSI, and so on, depending on how many transistors are included in a single package.

An embedded system is a computer that is specifically designed to do a single purpose. However, The term “VLSI” stands for “Very Large Scale Integration,” and it refers to the complexity of an integrated circuit as measured by the estimated number of semiconductors, also known as transistors.

There are a wide range of uses for embedded services, including those in industrial, commercial and military contexts. Designers of integrated circuits may save space by using VLSI technology. A CPU, RAM, OS, and various peripherals are common electrical circuits on a basic PCBA.

What is an Embedded System?

An embedded system is a microchip-based computer hardware and software system designed to accomplish a certain task. An embedded system is a computer that is specifically designed to do a single purpose. There are embedded systems in casinos, gateways, PCs, and mobile phones.

Using standard computer programming with particular modules, embedded systems may be programmed to run on a Microcontroller or CPU with an operating system, such as Ubuntu or Linux kernels. Examples include C/C++, Rust, Python, and a slew of others.

The frameworks and translators for these languages are usually supplied by your authorised manufacturer, letting you to concentrate on performance rather than specific translations into machine-level code.

Embedded systems is a lucrative field with a burgeoning following both in India and throughout the globe. If you are interested in a career in computer engineering, embedded systems are a great place to start. Engineers in India may expect to find a lot of work in embedded systems, which is a good thing for the country’s economy. Embedded systems’ machine languages are straightforward and easy to learn. Python, Rust, C++, and more are included.

What is a VLSI?

The term “extremely large-scale integration” refers to the process of placing thousands of transistors on a single crystalline silicon microchip (VLSI). When multicore processor microchips were being created in the late 1970s, VLSI technology was established.

In the creation of microprocessors, ICs, and other electronic components, VLSI is a commonly used method of design. On a microchip that by 2012 had reached billions of transistor terminals, it was designed to support hundreds and thousands of them.

Programmable logic devices such as MCUs, FPGAs, and others may be created using VLSI design techniques and languages. An MCU or an FPGA may be used as a pre-existing platform for embedded system design, with software created to run on top of it. As VLSI architecture comes closer to hardware design, it requires more attention to details like floor planning, layout, the size of the semiconductors, connection, the rate at which they run, and how much energy they use.

The scripting languages used in VLSI for the design of integrated circuits are called hardware description systems (HDLs). Programming languages like Python and TCL are among them. Developing a new VLSI product requires both a team’s strategy and the HDL it uses.

Difference between Embedded System and VLSI

  • A system’s hardware is handled by embedded systems, while its software and modulations are handled by VLSI.
  • VLSI relies on programming languages like C/C++, Rust, and Python, while embedded systems rely on hardware networking as their primary means of communication.
  • In contrast to VLSI, which focuses on internet networking and user interface design, embedded systems research works with semiconductors and circuits.
  • Embedded systems, on the other hand, are computer platforms that are designed to do a specific task.
  • AMD, Intel, and NVIDIA are the most prominent embedded system design businesses, while LSI, Qualcomm, and Samsung dominate the VLSI market.


Unless you’re designing for an embedded device or a VLSI for some new ICs, an engineer will always need suitable PCB modelling and planning tools to develop assessment boards, SoMs, SBCs, and other end products. Nevertheless, the name VLSI no longer exists because to its age and technical developments. There are tens of millions or perhaps hundreds of billions of transistors packed into every single computer system, whether it is embedded or ubiquitous.

Architectures and designs, on the other hand, are still in widespread use because of their practical efficacy. Embedded systems may be increasingly popular, but VLSI still provides strong architecture and software support, so it should be fine for another decade or more at the very least. Engineers in VLSI and embedded systems have similar work scopes, and both boards are based on integrated circuits and simplicity of use.
