An embedded system on a plug-in card with processor, memory, power supply, and external interfaces. An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
When they do use one, a wide variety of operating systems can be chosen from, typically a real-time operating system. Code for embedded software is typically written in C or C++, but various high-level programming languages, such as Java, Python and JavaScript, are now also in common use to target microcontrollers and embedded systems.

MISRA C is a set of software development guidelines for the C programming language developed by The MISRA Consortium.Its aims are to facilitate code safety, security, portability and reliability in the context of embedded systems, specifically those systems programmed in ISO C / C90 / C99.
Michael Barr is a software engineer specializing in software design for medical devices and other embedded systems. [1] [2] He is a past editor-in-chief of Embedded Systems Design magazine [3] and author of three books and more than seventy articles about embedded software. [4]
It targets real-time computing embedded systems, aiming to produce a design that is both highly abstract, and yet allows precise extraction of time and space execution costs. This allows guaranteeing the bounded time and space demands of executing programs. Hume combines functional programming ideas with ideas from finite-state automata.
For most Microchip microcontrollers, ICSP programming is performed using two pins, clock (PGC) and data (PGD), while a high voltage (12 V) is present on the Vpp/MCLR pin. Low voltage programming (5 V or 3.3 V) dispenses with the high voltage, but reserves exclusive use of an I/O pin.
Micro-Controller Operating Systems (MicroC/OS, stylized as μC/OS, or Micrium OS) is a real-time operating system (RTOS) designed by Jean J. Labrosse in 1991. It is a priority-based preemptive real-time kernel for microprocessors, written mostly in the programming language C. It is intended for use in embedded systems.
SystemC is an example of such—embedded system hardware can be modeled as non-detailed architectural blocks (black boxes with modeled signal inputs and output drivers). The target application is written in C or C++ and natively compiled for the host-development system; as opposed to targeting the embedded CPU, which requires host-simulation of ...
