Like embedded hardware, embedded software architecture is highly flexible. Simple embedded software (such as electronic toys, calculators, and so on) may be only a few thousand lines of code and perform simple input and output functions. On the other hand, complex embedded systems (such as smartphones, robots, and so on) need more complex software architecture, […]

Sensors:   The intrinsic part of the embedded system is the sensors. Right from simple tv remote to security systems installed at home. They are also becoming important for weather stations to forecast weather parameters(temperature, wind speed, wind direction, solar radiation, and many more) and in IoT(to gather data, sharing data etc). Definition and Working of

There are two ways to pass arguments to a function — Pass by Value and Pass by Address. The major difference between Pass by Value and Pass by Address is in the pass by value copy of actual arguments is passed to respective formal arguments. While, in the call by reference, the location (address) of

Macros are preprocessed, meaning that all the macros would be executed before the compilation stage. However, functions are not preprocessed but compiled. Example of Macro: #include<stdio.h> #define  A 10 int main() {      printf(“%d”,A);      return 0; }  OUTPUT=10; Example of Function: #include<stdio.h> int A() {     return 10; } int main() {     printf(“%d”, A());     return 0; }

The most important function of C is main() function. It is mostly defined with a return type of int and without parameters : int main() { /* … */ } We can also give command-line arguments in C . Command-line arguments are given after the name of the program in the command-line shell of Operating

In a program the most significant function is the main() function. It is defined with a return type of int and without arguments  int main()   {     /* … */   } Command-line arguments are typically the arguments given to the main function.It includes two arguments the first argument is the number of command line arguments and

The present VLSI electronic systems rely on the Silicon MOS (metal oxide semiconductor) technology which advances will soon come to saturation. Carbon nanotubes represent an advancement in the materials technology with the potential for providing switching devices that may be faster and smaller than the present MOS devices. Carbon nanotubes are miniature tube structures with

If a function is defined as a friend function in C++, then the protected and private data of a class can be accessed using the function. By using the keyword, the friend compiler knows the given function is a friend function. For accessing the data, the declaration of a friend function should be done inside

A Copy constructor is an overloaded constructor used to declare and initialize an object from another object. Copy Constructor is of two types: Default Copy constructor: The compiler defines the default copy constructor. If the user defines no copy constructor, the compiler supplies its constructor. User-Defined constructor: The programmer defines the user-defined constructor. Syntax Of

Bootstrapping in computer science is the technique for producing a self-compiling compiler. That is compiler/assembler written in the source programming language that it intends to compile. An initial core version of the compiler is generated in a different language mostly assembly language. Successive developed versions of the compiler are developed using this minimal subset of
