Difference between Embedded System and VLSI (With Table)

IC or integrated circuits often make us think of embedded systems with specialized processing capabilities, both in terms of concept and execution. Any smart device that tries to influence data using specialized, developer software is an embedded system, which may be done at a core level utilizing the VLSI or Very Large-Scale Integration processes. This article magnifies the features and usages of both embedded systems and VLSI to help you understand the differences between both types of integrated processes.

Embedded System vs VLSI

The difference between embedded systems and VLSI is that embedded systems architecture concentrates on developing code that is executed on a malleable piece of hardware whereas VLSI emphasizes converting programming commands into a framework for an integrated circuit or IC.

Any usage of technology that is utilized to accomplish a limited or specialized task is referred to as an embedded system. In contrast to an overall computer, which can execute a wide range of activities and is quite sophisticated, an embedded system is fairly simple and lacks superfluous equipment. Embedded systems can be found in Banks, modems, calculators, and cellular phones, to name a few examples.

VLSI on the other hand stands for ‘Very Large Scale Integration, which is a phrase being used to define the sophistication and complexity of an integrated circuit by estimating how many gates and transistors are present. VLSI refers to integrated circuits containing thousands of transistors in a single container; alternative acronyms, such as MSI or ULSI, are being used to represent ICs with fewer or more components.

What is an Embedded System?

A microchip-based computer hardware and software system that is built to meet a certain purpose is known as an embedded system. Any computing system that is utilized to accomplish a limited or specialized task is referred to as an embedded system. Embedded systems are available in Casinos, gateways, computers, and mobile phones, to name a few.

Standard computer linguistics with specific modules can be used to program embedded systems that will operate on a Microcontroller or CPU with an operating system, such as Ubuntu or mainly Linux kernels. C/C++, Rust, Python, and several other languages are examples.

The needed frameworks and translators for these languages are generally provided by your approved manufacturer, allowing you to focus on performance rather than particular translations into machine-level code.

When talking about the profession in embedded systems, the scenario is rich and currently quite popular in India as well as in the world itself. Embedded systems is a fascinating subject of computer engineering with many career prospects both now and in the foreseeable future. Embedded systems have more employment in India and the profession offers great opportunities for rising engineers. The machine languages used for embedded systems are simple and easy. It includes; python, Rust, C++, etc.

What is VLSI?

The technique of incorporating or integrating 1000s of transistors on a single crystalline silicon microchip is known as a very large-scale integration (VLSI). As expert-level multicore processor microchips were being developed in the late 1970s, VLSI technology was invented.

VLSI is a widely used technology for developing microchip computers, integrated circuits (ICs), and components. It was created to sustain hundreds and thousands of transistor terminals on a microchip that had grown to billions by 2012.

VLSI design processes and languages may be used to create MCUs, FPGAs, and other programmable logic devices that run embedded software. Embedded systems design often concentrates on the software side, with code written to operate on a pre-existing platform like an MCU or an FPGA. VLSI architecture necessitates strict attention to floorplanning, layout, semiconductor size, connectivity, clock, and energy distribution, including timing since it is closer to hardware design.

Hardware description systems are the scripting languages used in VLSI for IC design (HDLs). Verilog, VHDL, C, and programming languages like Python and TCL are among them. In VLSI, a team’s development approach is just as essential as the HDL they employ to create a new product.

Main Differences Between Embedded System and VLSI

  1. Embedded systems deal with the hardware of a system whereas VLSI is responsible for the software and modulations.
  2. Hardware networking is the core of embedded systems whereas programming languages like C/C++, Rust, and Python are required for VLSI.
  3. Embedded systems study the semiconductors and circuits whereas the VLSI deals with internet networking and UI designing.
  4. An embedded system is a computer platform that performs a particular purpose whereas VLSI is a measurement of the intricacy of an integrated circuit.
  5. Leading companies involved in the embedded system designing are AMD, Intel, NVIDIA whereas VLSI is dominated by LSI, Qualcomm, and Samsung.


An engineer will always require proper PCB simulation and planning tools to construct assessment boards, SoMs, SBCs, and other final products unless you’re designing for an embedded device or a VLSI for some new ICs. However, because of its age and technological advancements, the term VLSI has virtually become obsolete. Electronic components in most computer systems, whether embedded or universal, include thousands, millions, or even billions of transistors in a complete unit.

Both the architectures and designs however are functionally efficient and are still widely used. Despite the fact that embedded systems are more popular because of their price and manufacturing ease, VLSI still offers decent architecture and software support so it is definitely good to go for another decade at least. The job scope for VLSI is rich and comparable to the embedded system designers and both the boards are based on IC integration and ease of usage.
