He did the development on a 68360 target so the m68k has been tested. Others have tested the stack on a PC (WD8003), i386ex (Intel 82596), ColdFire (don't remember), and a PowerPC (Sonic). The performance of the stack is impressive with Eric's 25 Mhz 68360 reporting 1000 Mbytes/sec transmit and receive rates using the ttcp benchmark. This is 3-5x faster than the KA9Q stack could do. FreeBSD is also now a supported development host and a target OS for the "UNIX port" of RTEMS. The UNIX port of RTEMS lets you test RTEMS applications running as native processes under UNIX. Real hardware is virtualized so UNIX signals are interrupts, alarm generates the clock tick, setjmp is used for context switches, etc. There are some things which can not be used in this mode but given a volunteer those could be fixed. I should also mention that Wes Peters mentions RTEMS in next month's edition of the online ezine Daemon News (http://www.daemonnews.org). --joel Joel Sherrill Director of Research & Development joel@OARcorp.com On-Line Applications Research Ask me about RTEMS: a free RTOS Huntsville AL 35805 Support Available (256) 722-9985 > Cheers, > > Jerry Hicks > jerry.hicks@glenayre.com > > ----------------------------------- > > From: joel@OARcorp.com > Subject: Re: RTEMS with IP stack. > > > Is there a estimated release date for RTEMS with a TCP/UDP/IP stack ? > > Yes.
