Tiny can be defined as a minimalist runtime environment for low-end embedded systems. It aims at speeding up the validation process for new board designs as well as the development of very low-level drivers/algorithms. It has been named after its code footprint which can be very small (a few tens of Kbytes) depending on what features you want to include. Tiny has been written from scratch in C and assembly and does not require any extra library to compile. All the required functions/drivers are included in the source tree and it comes along with makefiles and linker scripts to generate elf, binary and srec files out of your code. It may be turn into a very small bootloader or an installer/flasher when needed. To keep the code clear and the makefiles simple, all arch have their own "branch". Tiny is also a valuable educative ressource since it shows at the very low level how to use a particular CPU (and surrounding ressources found in many SoCs).

Tiny is using a flat memory model architecture. Provinding basic standard libraries, dynamic memory management and a few filesystems support, it targets low memory footprint applications for deeply embedded devices. All this with an ultra fast execution time and without sacrifying some highly convenient capabilities such as interactive console and graphical capabilities.
Support varies depending on the target and its peripheral set.
