The open-source eCos (Embedded Configurable Operating System) is ideal for deeply embedded systems in which memory resources and real-time execution constraints are top design issues. The system supports a range of development platforms—from standard PCs to PDAs—using many of the most popular embedded processors. Comprehensive device drivers, supported platforms, and third-party software offerings make eCos ideal for any embedded device. The royalty-free eCos RTOS, a good choice for embedded applications, supports Gnu open-source development tools, and, because eCos is open-source you can download and test eCos for free (Reference 1). A new release, Version 2.0, is due out in the coming months. You can find the latest information about new ports for eCos and other related information on the eCos Web site.
