An embedded computer is a system that has been specially designed to perform a set of dedicated functions. An embedded system is typically based on microcontrollers and can be used in devices such as automobiles, industrial machinery and consumer electronics.
The main components of embedded pcs include:
The processor is the brain of your embedded system computer. It directs all of the other components and is responsible for processing everything that happens within your system. The processor is what makes it possible for your system to function at all.
Memory is the part of your embedded system where data is stored temporarily while the processor processes it. Data is processed by changing the memory in some way, then sent back to memory when it’s finished being processed. Memory can be volatile or nonvolatile: volatile memory loses its information when power is removed from an embedded system, while nonvolatile memory retains its information even if power goes away (e.g., flash memory).
Timers and counters allow you to measure time with precise accuracy over long periods of time (up to 100 millionths of a second). You can use them to monitor events in real-time or control processes that require exact timing — like blinking an LED on and off every 1/100th of a second!
Output and Input
Outputs are the components that perform actions like displaying data on a screen or sending data to the printer. Outputs also perform actions like controlling motors and relays etc. Inputs are those components that receive input from external devices for further processing by embedded system computer such as keyboard, mouse etc..
These ports allow communication between two devices. Some of these communication ports include USB, RS-232, Ethernet and Bluetooth. These ports may be implemented using transceivers or with the help of a microcontroller which implements a serial interface protocol such as UART, SPI or I2C.
An assembler is a programming language that allows you to write code in a low-level language such as assembly language. The assembler then converts your code into machine language so that it can be understood by the computer.
An emulator is a program that can mimic another program or device. For example, if you wanted to test out an application on your computer before installing it, then an emulator would allow you to do this by simulating the operating system on which the application would run normally. It’s also possible to use emulators for other purposes such as creating virtual machines on your computer or developing software for mobile devices without having access to them physically (i.e., through remote access).
Top Components of Embedded System Computers - In a world of technological developments, you cannot but take advantage of the numerous inventions that have taken place. Government bodies are using them to manage remote areas while business individuals have embraced the use of these computers in the various aspects of their businesses. There is an endless list of components that form this system, and it can be overwhelming if you are not acquainted with the right information.
