Contiki is an open source, highly portable, multi-tasking operating
|
|
system for memory-constrained networked embedded systems written by
|
|
Adam Dunkels at the Networked Embedded Systems group at the Swedish
|
|
Institute of Computer Science.
|
|
|
|
Contiki is designed for embedded systems with small amounts of
|
|
memory. A typical Contiki configuration is 2 kilobytes of RAM and 40
|
|
kilobytes of ROM. Contiki consists of an event-driven kernel on top of
|
|
which application programs are dynamically loaded and unloaded at
|
|
runtime. Contiki processes use light-weight protothreads that provide
|
|
a linear, thread-like programming style on top of the event-driven
|
|
kernel. Contiki also supports per-process optional preemptive
|
|
multi-threading, interprocess communication using message passing
|
|
through events, as well as an optional GUI subsystem with either
|
|
direct graphic support for locally connected terminals or networked
|
|
virtual display with VNC or over Telnet.
|
|
|
|
Contiki contains two communication stacks: uIP and Rime. uIP is a
|
|
small RFC-compliant TCP/IP stack that makes it possible for Contiki to
|
|
communicate over the Internet. Rime is a lightweight communication
|
|
stack designed for low-power radios. Rime provides a wide range of
|
|
communication primitives, from best-effort local area broadcast, to
|
|
reliable multi-hop bulk data flooding.
|
|
|
|
Contiki runs on a variety of platform ranging from embedded
|
|
microcontrollers such as the MSP430 and the AVR to old
|
|
homecomputers. Code footprint is on the order of kilobytes and memory
|
|
usage can be configured to be as low as tens of bytes.
|
|
|
|
Contiki is written in the C programming language and is freely
|
|
available as open source under a BSD-style license. More information
|
