Embedded Systems

Embedded Systems

1. is a

   • system can only do an specific task in comparison with a personal computer,fabricated in a silicon slice called integrated circuits

2. works

   • With a program(software) and the mechanical part(hardware)
     • The sofware need to be storage in two types of memory a non volatil memory to run always the program(ROM) and the voatil memory to storage the temporary memory(the results of ALU) called RAM
       • for the program
         • We need to write it in a form that the system could understand and we have some options to choose like C,C++,Fortran,Java and Assambler
         • How to do?
           • We have two forms the first one is with few and huge instructions and the the second one is with a lot of short instructions
   • like a computer and has a arithmetic logic unity that can do any arithmetic operation with the data coming from the Input peripheral and then the central unit operation process it to realize the task and finally show the results in the output peripherals

3. some examples

   • vending machine,washing machine,toaster, camera

4. the devolopment

   • 1-Write the code 2.-Compile 3.-Simulate 4.- Test in hardware
