What is the difference between C and embedded C

Question

Can any body tell me the differences between them

User · Answer

Embedded C is generally an extension of the C language  they are more or less similar  However  some differences do exist  such as    C is generally used for desktop computers  while embedded C is for microcontroller based applications  C can use the resources of a desktop PC like memory  OS  etc  While  embedded C has to use with the limited resources  such as RAM  ROM  I Os on an embedded processor  Embedded C includes extra features over C  such as fixed point types  multiple memory areas  and I O register mapping  Compilers for C  ANSI C  typically generate OS dependant executables  Embedded C requires compilers to create files to be downloaded to the microcontrollers microprocessors where it needs to run    Refer difference between C and embedded C

Embedded environment  sometime  there is no MMU  less memory  less storage space  In C programming level  almost same  cross compiler do their job

1  C is a type of computer programming language     While embedded C is a set of language extensions for the C Programming language   2  C has a free-format program source code  in a desktop computer     while embedded C has different format based on embedded processor  micro-     controllers microprocessors    3  C have normal optimization  in programming     while embedded C high level optimization in programming   4  C programming must have required operating system     while embedded C may or may not be required operating system   5  C can use resources from OS  memory  etc  i e all resources from desktop computer can     be used by C      while embedded C can use limited resources  like RAM  ROM  and I Os on an embedded      processor

In the C standard  a standalone implementation doesn t have to provide all of the library functions that a hosted implementation has to provide   The C standard doesn t care about embedded  but vendors of embedded systems usually provide standalone implementations with whatever amount of libraries they re willing to provide   C is a widely used general purpose high level programming language mainly intended for system programming   Embedded C is an extension to C programming language that provides support for developing efficient programs for embedded devices It is not a part of the C language  You can also refer to the articles below    Difference  between C and Embedded C   Embedded C   ISO IEC J TC1 SC22 WG14 N1169

Basically  there isn t one   Embedded refers to the hosting computer   microcontroller  not the language   The embeddded system might have fewer resources and interfaces for the programmer to play with  and hence C will be used differently  but it is still the same ISO defined language

C is a only programming language its used in system programming  but embedded C is used to implement the projects like real time applications

c cant access physical address  embedded c can access physical address embedded c variable address is stored in stack  in embedded c variable should be declaired at the begining of the block embedded c input output port are used but in c printf and scanf used
