Performance Analysis of Embedded Linux in Embedded System

Nowadays, embedded systems with Linux OS are commonly applied in automotive industry. This paper represents two features of embedded system namely multithreading and semaphore in embedded linux. The flow charts are used to represent the program written in ‘C’, run on linux operating system .In multithreading the same string is printed continuously till you print ‘stop’ while by using semaphore the string will print only once and asking for another one. By using this we can build our own embedded system using linux as the kernel and freely available open source.
