- <h3><a name="History"></a>History</h3>
-This RTOS is something I wrote back in 1990 for use on boards
-equipped
-with M68K processors, the development was made on an Atari ST. The OS
-worked well for its intended purpose, Internet was not
-widespread at that time so the system had a limited use.<br>
-Recently I decided to release this system, formerly known as <span style="font-style: italic;">mkRTOS</span>, as Free
-Software. I cleaned up the code, improved the documentation, ported it
-to more modern architectures and it is finally ready.<br>
- <h3><a name="Description"></a>Description</h3>
-ChibiOS/RT is designed for embedded applications and it is meant to be
-linked with the application code. The design philosophy is to make it
-easy to use so I hope that all the APIs are meaningful, easy to
-understand and with the parameters you would expect from them.<br>The
-system offers threads, semaphores, mutexes, messages, events, virtual
-timers,
-queues, I/O channels with timeout capability and much more. The
-Priority Inheritance algorithm is implemented through the Mutexes
-mechaninsm, the implementation supports any number of threads and
-nested mutexes.<br>
- <h3><a name="Current_ports"></a>Current
-ports</h3>
-Currently the ChibiOS/RT is ported to the following architectures:<br>
- <ul>
- <li>ARM7TDMI-LPC214x, the port to other LPC2000 chips
-should be trivial. Both ARM and THUMB modes are supported.</li>
- <li>ARM7TDMI-AT91SAM7X256, this port also supports other Atmel
-chips: SAM7XC, SAM7S and the various sizes (128, 256, 512) with
-minimal changes.</li>
- <li>ARM Cortex-M3, ST Microelectronics STM32.</li>
- <li>Atmel AVR: AT90CAN128 and ATmega128 demos included.</li>
- <li>Texas Instruments MSP430.</li>
- <li>x86 as a Win32 process, this port allows to write
-your application on the PC without the need of a development
-board/simulator/emulator. Communication ports are simulated over
-sockets, you can telnet on the simulator ports for the debug. I am
-considering to create a similar simulator into a Linux process.</li>
- <li>M68K, this was the original target but it is
-currently removed from the source tree because currently I have no way
-to test it, my old Atari ST is long dead. It should be very easy to
-revive the port to the M68K or Coldfire CPUs.</li>
- </ul>
-In general the port is very easy on architectures that can handle well
-linked lists, the kernel is entirely reliant on lists so this
-is a
-very important efficiency factor. 16 and 32 bits architectures are
-always fine, 8 bit architectures should be evaluated case by case but
-are not ruled out, something like an H8 would not have problems. You
-could port it
-to a Z80/Z180 (I considered that too, and made tests using the SDCC
-compiler) but the
-resulting code is not much efficient because the instruction set is
-missing the indirect addressing for 16 bits values that is important
-for efficient linked lists traversal.
- <h3><a name="Design"></a>Design</h3>
-The system was designed to be stable and avoid trouble as much as
-possible so some rules were set:<br>
- <ul>
- <li>No arrays or tables, I don't like to have to
-configure limits
-for data structures, only use lists or other dynamic data structures.
-See
-the <a href="http://chibios.sourceforge.net/html/index.html" target="_top" rel="me">Documentation</a> and
-the demos.</li>
- <li>No memory allocation inside the kernel, an allocator
-can be
-troublesome for RT applications. All the data structures are declared
-in the application code and not allocated from a shared system heap.
-This does not prevent the application code to use an allocator if
-needed, it is just the kernel that does not require it.</li>
- <li>No weird macros in the user code, everything should
-look
-and feel like normal C code with a normal main() function.</li>
- <li>Encapsulate all the things that need changes while
-porting
-the OS to new architectures in few template files, fill the code into
-the templates and the port is done.</li></ul><h3><a name="Performance_and_Size"></a>Performance and Size</h3>ChibiOS/RT
-has a wide set of APIs but all the subsystems can be included or
-removed from the memory image by editing the kernel configuration file
-chconf.h. On ARM processors, the kernel size starts at just
-1.5KiB depending on the included subsystems and the choosen
-compiler optimizations.<br>As reference, a kernel configured with...<br><ul><li>System startup code</li><li>Chip initialization code</li><li>Multithreading APIs</li><li>Virtual Timer APIs</li><li>Semaphore APIs</li><li>System time + Sleep API</li><li>Suspend/Resume APIs</li><li>Small main() program with flashing LEDs demo and 3 threads</li></ul>...just takes 2.11KiB of program space when compiled using THUMB code and space optimizations. Note that this is quite a <span style="font-weight: bold;">typical configuration</span>
-not a minimal one. A kernel configured with all the options and
-optimized for speed takes about 6KiB. See the documentation about the
-many available subsystems.<br><br>About performance, on a 48MHz LPC
-ARM7 processor the kernel is capable of context switch time ranging
-from 3 to 6 microseconds depending on the code type (ARM/THUMB) and the
-choosen compiler/kernel optimizations. In the distribution is included
-a spreadsheet with the exact values and the various space/time trade
-offs.<br>The context switch time is *measured* using 2 threads
-exchanging messages and doing *real* work, it is not a calculated peak
-value. See the demo code, it includes the benchmark.
- <h3><a name="Future"></a>Future</h3>
-Expect:<br><ul>
-
- <li>Documentation improvements.</li>
-
- <li>Ports to more architectures/boards when I am able to
-put my hands on new hardware/tools.</li>
- <li>More demos.</li>
- <li>Creation of new subsystems.</li>
- <li>Integration with
-existing other free projects like: TCP/IP stacks, File Systems etc.</li>
- </ul>
