Key Features</H1 ><P ></P ><UL ><LI ><P ><SPAN CLASS="PRODUCTNAME" >eCos</SPAN > is distributed under the GPL license with an exception which permits proprietary application code to be linked with <SPAN CLASS="PRODUCTNAME" >eCos</SPAN > without itself being forced to be released under the GPL. It is also royalty and buyout free.</P ></LI ><LI ><P >As an Open Source project, <SPAN CLASS="PRODUCTNAME" >eCos</SPAN > is under constant improvement, with an active developer community, based around the <SPAN CLASS="PRODUCTNAME" >eCos</SPAN > web site at <A HREF="http://sources.redhat.com/ecos/" TARGET="_top" >http://sources.redhat.com/ecos/</A >.</P ></LI ><LI ><P >Powerful GUI-based configuration system allowing both large and fine grained configuration of <SPAN CLASS="PRODUCTNAME" >eCos</SPAN >. This allows the functionality of <SPAN CLASS="PRODUCTNAME" >eCos</SPAN > to be customized to the exact requirements of the application.</P ></LI ><LI ><P >Full-featured, flexible, configurable, real time embedded kernel. The kernel provides thread scheduling, synchronization, timer, and communication primitives. It handles hardware resources such as interrupts, exceptions, memory and caches.</P ></LI ><LI ><P >The Hardware Abstraction Layer (HAL) hides the specific features of each supported CPU and platform, so that the kernel and other run-time components can be implemented in a portable fashion.</P ></LI ><LI ><P >Support for µITRON and POSIX Application Programmer Interfaces (APIs). It also includes a fully featured, thread-safe ISO standard C library and math library.</P ></LI ><LI ><P >Support for a wide variety of devices including many serial devices, ethernet controllers and FLASH memories. There is also support for PCMCIA, USB and PCI interconnects.</P ></LI ><LI ><P >A fully featured TCP/IP stack implementing IP, IPv6, ICMP, UDP and TCP over ethernet. Support for SNMP, HTTP, TFTP and FTP are also present.</P ></LI ><LI ><P >The RedBoot ROM monitor is an application that uses the <SPAN CLASS="PRODUCTNAME" >eCos</SPAN > HAL for portability. It provides serial and ethernet based booting and debug services during development.</P ></LI ><LI ><P >Many components include test programs that validate the components behaviour. These can be used both to check that hardware is functioning correctly, and as examples of <SPAN CLASS="PRODUCTNAME" >eCos</SPAN > usage.</P ></LI ><LI ><P ><SPAN CLASS="PRODUCTNAME" >eCos</SPAN > documentation included this User Guide, the Reference Manual and the Components Writer's Guide. These are being continually updated as the system develops.</P ></LI ></UL ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="user-guide-introduction.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="ecos-user-guide.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="ecos-overview.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Introduction</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="user-guide-introduction.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><SPAN CLASS="PRODUCTNAME" >eCos</SPAN > Overview</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
