ABOUT RETROBSD PROJECT

RetroBSD is a port of 2.11BSD Unix intended for embedded systems with fixed
memory mapping. The current target is Microchip PIC32 microcontroller with 128
kbytes of RAM and 512 kbytes of Flash. PIC32 processor has MIPS M4K
architecture, executable data memory and flexible RAM partitioning between user
and kernel modes.



Main features:

 * Small resource requirements. RetroBSD requires only 128 kbytes of RAM to be
   up and running user applications.
 * Memory protection. Kernel memory is fully protected from user application
   using hardware mechanisms.
 * Open functionality. Usually, user application is fixed in Flash memory - but
   in case of RetroBSD, any number of applications could be placed into SD card,
   and run as required.
 * Real multitasking. Standard POSIX API is implemented (fork, exec, wait4 etc).
 * Development system on-board. It is possible to have C compiler in the system,
   and to recompile the user application (or the whole operating system) when
   needed.

Visit RetroBSD.org for documentation and forum discussions.
