Newlib

Newlib is a C standard library, optimized for the creation of projects in embedded systems. Newlib is a compilation of fundamental, speed and size optimized parts of the standard C library is available under free software licenses, and is an open source before. Originally developed by Cygnus Solutions, Newlib after its acquisition by Red Hat maintained.

Since Newlib is open source, it can be compiled for a variety of processor families, and is due to this flexibility widely used in microcontroller- based software projects. This ranges from small devices with 8- bit processors (eg Atmel AVR ) to the current 32 -bit architectures.

Various commercial GCC distributions For example, if CodeSourcery, Atollic and Red, use newlib as a base in the area of embedded systems. Furthermore, experiences the development of Newlib support by manufacturers of embedded processor architectures such as ARM Limited and Renesas Electronics.
