Key Features of Field Programmable Gate Arrays (FPGAs)
A field programmable gate array (FPGA) utilizes an array of logic blocks, which can be configured by the user. The term “field programmable” implies that the device is programmable outside the factory where it is produced. The internal architecture of a FPGA device has three main parts, namely: The figure below illustrates the architecture of…

Design Metrics Employed in Embedded Systems
We have a number of design metrics you need to put into consideration when designing embedded systems. The following are some of the key design metrics used in embedded systems: Performance The instruction execution time in the system measures the performance. Smaller execution time means higher performance. For example, for a digital camera, shooting a…

Networked Embedded Systems
Each specific IO device can be connected to others using specific interfaces, for instance, an IO device connects and is interfaced to an LCD controller, keyboard controller, or print controller using specific interface. Bus communication simplifies the number of connections and provides a common protocol for interconnecting different or same type of IO devices. Any…

Applications of Embedded Systems
Embedded systems have varied applications for example, they are used in smart cards, computer networking, digital consumer electronics, telecommunications, satellites, just to name a few. We may classify embedded systems applications into 3 categories: Examples of small scale embedded applications include: Some of the examples of medium scale embedded systems applications include: Examples of Sophisticated…

What is Embedded Java?
Embedded Java is a Java version that makes large program development simpler by providing complete object-oriented programming (OOP) features in Java. JVM is configured to minimize memory requirements and run-time overheads in the system. Embedded System programmers use Java in a large number of readily available classes for the IO stream, network and security. Java…

10 Reasons to Consider Java for Embedded Systems Programming
Java as a high level programming language has grown over the years into a full-fledged language with an enormous user base. It is used extensively for instance, in building web applications with frameworks such as Spring Boot. Java has also found a formidable utilization in programming embedded systems, and this is due to the following…

Classifications of Embedded Systems
Embedded systems can be classified into three types: Small Scale Embedded Systems These are systems that are designed with a single 8-bit or 16-bit microcontroller. They have small hardware and software complexities and involve board-level design. These systems can even be battery operated. When developing embedded software for this system type, an editor, assembler, and…

Embedded System-On-Chip (SoC)
System-on-chip (SoC) is a system on VLSI chip that has all the required analog as well as digital circuits, processors and software. At the heart of most SoC designs are an embedded proprietary RISC processor and a block of RAM memory (for the software that runs on the processor). This allows the designer to partition…

Features of an Embedded System
An embedded system can defined as a system that has embedded software and computer-hardware, which makes it a system dedicated for an application (s) or specific part of an application or product or a part of a larger system. An embedded system is characterized by the following: An embedded system is usually designed by keeping…
