eCos

Company:

eCosCentric Limited

Description:

eCosŪ is the premier open source real-time operating system. A mature and robust system, it has many design wins to its credit in a diverse range of market segments including industrial automation, consumer electronics, telematics, aerospace, multimedia and telecommunications. In the fragmented embedded operating systems market eCos is one of the major players, with global market usage of around 5-6% according to CMP´s Embedded Study 2007, and EDC´s Embedded Development Survey 2007. Examples of products that incorporate eCos include the Sony PlayStation 3, Sirius satellite radios, Netgear routers, Raytheon Patriot missile system, Samsung LCD TVs, ESA SSETI Express satellite, Hitachi VOIP phones, and Compllent SANs.

eCos includes the tools and runtime functionality necessary for general embedded applications: standards based APIs, libraries, filesystems, networking, communications, compatibility layers, graphics, and debugging support.

eCos implements a classic multi-threaded architecture with a rich set of synchronization primitives. This delivers deterministic response times, minimal interrupt latencies, and low overhead context switches.

One size does not fit all. Using advanced configuration technology eCos can be tuned to meet your application's specific functional and performance requirements.

Highly portable at both the architectural and platform levels, eCos is available for all major 32 bit embedded architectures.

eCos is truly free open source software - no royalties, and a licence that ensures unlimited access to its source base, whilst respecting the IP rights of middleware and applications.
