Embedded Software Development with eCos shows developers and managers the advantages of using eCos -- the Embedded Configurable Operating System from Red Hat - over proprietary or commercial embedded operating systems. As an Open Source solution, eCos provides a low-cost, royalty free option for embedded software development. Anthony Massa shows how eCos, and the eCos development environment, has all of the features and functionality to meet the needs of almost all commercial embedded system requirements. Massa provides an understanding of how to use the open-source licensing and royalty free nature of eCos in order to eliminate high startup and per unit costs associated with many of the proprietary real-time operating systems on the market today. Embedded systems are operating systems that must operate with a very small footprint (usually less than 100KB of space) and must be self-contained. Most companies use either proprietary solutions or expensive commercial solutions. eCos is the first powerful, royalty-free Open Source solution, from Red Hat.
