As I understood some of the early information on Elix, it was
intended to be a standard/specification for embedded POSIX as
well as an implementation. Given this understanding, I would
like to offer RTEMS as an existing implementation of the Elix
specification.
Today, as best I can tell from the information I
have seen, RTEMS includes nearly every POSIX feature
required by the specification. At this point, RTEMS
includes the following mentioned in the Elix specification:
+ approximately 85% of the functionality of POSIX 1003.1b
including POSIX threads, signals, etc.
+ a port of the FreeBSD TCP/IP stack
Other features include:
+ filesystem support
+ httpd web server (GoAhead)
+ ftpd server
+ numerous network client services including DNS and TFTP
+ Classic API (based on same specification as pSOS+)
+ initial ITRON 3.0 support
+ remote debugging via Ethernet
+ multiprocessor support
RTEMS provides this functionality today for deeply embedded systems.
Elix is a new presentation of ideas espoused by the RTEMS Team for
years.
By providing compatability with standards, third party software can be
ported
easily to the RTEMS environment. This has enabled a variety of packages
including CORBAS, TCL, zlib, libavl, and ncurses to be easily ported to
RTEMS. More often than not, it is just a matter of passing the right
options to configure. :)
Basically, I just want to make sure that RTEMS gets a fair technical
shake
as an alternative -- and existing -- implementation of Elix for embedded
systems.
